With respect to timing, for cardiac arrest with a nonshockable rhythm, it is reasonable to administer epinephrine as soon as feasible. In patients with persistent hemodynamically unstable bradycardia refractory to medical therapy, temporary transvenous pacing is reasonable to increase heart rate and improve symptoms. Accurate neurological prognostication is important to avoid inappropriate withdrawal of life-sustaining treatment in patients who may otherwise achieve meaningful neurological recovery and also to avoid ineffective treatment when poor outcome is inevitable (Figure 10).3. In patients who remain comatose after cardiac arrest, it is reasonable to perform multimodal neuroprognostication at a minimum of 72 hours after normothermia, though individual prognostic tests may be obtained earlier than this. EMS systems that perform prehospital intubation should provide a program of ongoing quality improvement to minimize complications and track overall supraglottic airway and endotracheal tube placement success rates. The AED arrives. 4. IV infusion of epinephrine is a reasonable alternative to IV boluses for treatment of anaphlaxis in patients not in cardiac arrest. Synchronized cardioversion is recommended for acute treatment in patients with hemodynamically unstable SVT. After successful maternal resuscitation, the undelivered fetus remains susceptible to the effects of hypothermia, acidosis, hypoxemia, and hypotension, all of which can occur in the setting of post-ROSC care with TTM. Atropine has been shown to be effective for the treatment of symptomatic bradycardia in both observational studies and in 1 limited RCT. Three studies evaluated quantitative pupillary light reflex. Based on the protocols used in clinical trials, it is reasonable to administer epinephrine 1 mg every 3 to 5 min for cardiac arrest. Components include venous cannula, a pump, an oxygenator, and an arterial cannula. Cyanide poisoning may result from smoke inhalation, industrial exposures, self-poisoning, terrorism, or the administration of sodium nitroprusside. 3. Limited evidence for this intervention consists largely of observational studies, many of which have focused on indications and the relatively high complication rate (including bloodstream infections and pneumothorax, among others). When an emergency or disaster does occur, fire and police units, emergency medical personnel, and rescue workers rush to damaged areas to provide aid. CPR is the single-most important intervention for a patient in cardiac arrest and should be provided until a defibrillator is applied to minimize interruptions in compressions. *Red Dress DHHS, Go Red AHA ; National Wear Red Day is a registered trademark. The next steps in care, including the performance of CPR and the administration of naloxone, are discussed in detail below. 6. The ILCOR systematic review included studies regardless of TTM status, and findings were correlated with neurological outcome at time points ranging from hospital discharge to 12 months after arrest.4 Quantitative pupillometry is the automated assessment of pupillary reactivity, measured by the percent reduction in pupillary size and the degree of reactivity reported as the neurological pupil index. In addition to standard ACLS, several therapies have long been recommended to treat life-threatening hyperkalemia. However, there are several case reports of good maternal and fetal outcome with the use of TTM after cardiac arrest. 1. While ineffective in terminating ventricular arrhythmias, adenosines relatively short-lived effect on blood pressure makes it less likely to destabilize monomorphic VT in an otherwise hemodynamically stable patient. What is the validity and reliability of ETCO. We recommend that laypersons initiate CPR for presumed cardiac arrest, because the risk of harm to the patient is low if the patient is not in cardiac arrest. defibrillation? Alternatives to IV access for acute drug administration include IO, central venous, intracardiac, and endotracheal routes. Like all patients with cardiac arrest, the immediate goal is restoration of perfusion with CPR, initiation of ACLS, and rapid identification and correction of the cause of cardiac arrest. You recognize that a task has been overlooked. Which populations are most likely to benefit from ECPR? The key drivers of successful resuscitation from OHCA are lay rescuer cardiopulmonary resuscitation (CPR) and public use of an automated external defibrillator (AED). Cycles of 5 back blows and 5 chest thrusts. For patients with an arterial line in place, does targeting CPR to a particular blood pressure improve Rescuers should recognize that multiple approaches may be required to establish an adequate airway. When evaluated with other prognostic tests after arrest, the usefulness of rhythmic periodic discharges to support the prognosis of poor neurological outcome is uncertain. Clinical trials and observational studies since the 2010 Guidelines have yielded no new evidence that routine administration of sodium bicarbonate improves outcomes from undifferentiated cardiac arrest and evidence suggests that it may worsen survival and neurological recovery. 4. 4. Many cardiac arrest patients who survive the initial event will eventually die because of withdrawal of life-sustaining treatment in the setting of neurological injury. They may be used in patients with heart failure with preserved ejection fraction. 1. Hypotension may worsen brain and other organ injury after cardiac arrest by decreasing oxygen delivery to tissues. The toxicity of cyanide is predominantly due to the cessation of aerobic cell metabolism. Multiple agents, including magnesium, coenzyme Q10 (ubiquinol), exanatide, xenon gas, methylphenidate, and amantadine, have been considered as possible agents to either mitigate neurological injury or facilitate patient awakening. On the basis of your assessment findings, you begin CPR to improve the patient's chances of survival. affect resuscitation outcomes? No shock waveform has proved to be superior in improving the rate of ROSC or survival. Can artifact-filtering algorithms for analysis of ECG rhythms during CPR in a real-time clinical setting How is a child defined in terms of CPR/AED care? Acute increase in right ventricular pressure due to pulmonary artery obstruction and release of vasoactive mediators produces cardiogenic shock that may rapidly progress to cardiovascular collapse. 3. Other testing of serum biomarkers, including testing levels over serial time points after arrest, was not evaluated. Check for no breathing or only gasping; if none, begin CPR with compressions. 2. You are providing care for Mrs. Bove, who has an endotracheal tube in place. 2. City of Memphis via AP. What is the optimal approach, vasopressor or transcutaneous pacing, in managing symptomatic In these cases, this maneuver should be used even in cases of potential spinal injury because the need to open the airway outweighs the risk of further spinal damage in the cardiac arrest patient. medications? It may be reasonable to administer IV lipid emulsion, concomitant with standard resuscitative care, to patients with local anesthetic systemic toxicity (LAST), and particularly to patients who have premonitory neurotoxicity or cardiac arrest due to bupivacaine toxicity. Lidocaine is not included as a treatment option for undifferentiated wide-complex tachycardia because it is a relatively narrow-spectrum drug that is ineffective for SVT, probably because its kinetic properties are less effective for VT at hemodynamically tolerated rates than amiodarone, procainamide, or sotalol are. Adenosine is recommended for acute treatment in patients with SVT at a regular rate. Notably, in a clinical study in adults with outof- hospital VF arrest (of whom 43% survived to hospital discharge), the mean duty cycle observed during resuscitation was 39%. You yell to the medical assistant, "Go get the AED!" Are glial fibrillary acidic protein, serum tau protein, and neurofilament light chain valuable for and 4. 1. 2. She is 28 weeks pregnant and her fundus is above the umbilicus. 2. Atrial fibrillation is an SVT consisting of disorganized atrial electric activation and uncoordinated atrial contraction. Limited animal data and rare case reports suggest possible utility of calcium to improve heart rate and hypotension in -adrenergic blocker toxicity. CPR indicates cardiopulmonary resuscitation; ET, endotracheal; IO, intraosseous; IV, intravenous; PEA, pulseless electrical activity; pVT, pulseless ventricular tachycardia; and VF, ventricular fibrillation. Intracardiac drug administration was discouraged in the 2000 AHA Guidelines for CPR and Emergency Cardiovascular Care given its highly specialized skill set, potential morbidity, and other available options for access.1,2 Endotracheal drug administration results in low blood concentrations and unpredictable pharmacological effect and has also largely fallen into disuse given other access options. You suspect that an unresponsive patient has sustained a neck injury. The emergency should not be terminated until a Recovery Plan Outline has been developed and a Recovery Organization identified. No shock waveform has distinguished itself as achieving a consistently higher rate of ROSC or survival. If an arterial line is in place, an abrupt increase in diastolic pressure or the presence of an arterial waveform during a rhythm check showing an organized rhythm may indicate ROSC. The same anticonvulsant regimens used for the treatment of seizures caused by other etiologies may be considered for seizures detected after cardiac arrest. Does hospital-based protocolized discharge planning for cardiac arrest survivors improve access to/ Verapamil is a calcium channel blocking agent that slows AV node conduction, shortens the refractory period of accessory pathways, and acts as a negative inotrope and vasodilator. Discharges on EEG were divided into 2 types: rhythmic/periodic and nonrhythmic/periodic. In adult cardiac arrest, total preshock and postshock pauses in chest compressions should be as short as possible. -Adrenergic blockers may be used in compensated patients with cardiomyopathy; however, they should be used with caution or avoided altogether in patients with decompensated heart failure. For shockable rhythms, trial protocols have directed that epinephrine be given after the third shock. Several observational studies have demonstrated improved neurologically favorable survival when early coronary angiography is performed followed by PCI in patients with cardiac arrest who have a STEMI. Transition activities are performed while in a classified event and immediately after termination. We recommend that cardiac arrest survivors have multimodal rehabilitation assessment and treatment for physical, neurological, cardiopulmonary, and cognitive impairments before discharge from the hospital. 1. We recommend that laypersons initiate CPR for presumed cardiac arrest, because the risk of harm to the patient is low if the patient is not in cardiac arrest. Recommendations 1, 3, and 5 last received formal evidence review in 2015.10Recommendation 2 last received formal evidence review in 2015,10 with an evidence update completed in 2020.11 Recommendation 4 last received formal evidence review in 2010.12. You should give 1 ventilation every: You and two nurses have been performing CPR on a 72-year-old patient, Ben Phillips. The benefit of an oropharyngeal compared with a nasopharyngeal airway in the presence of a known or suspected basilar skull fracture or severe coagulopathy has not been assessed in clinical trials. The relative contribution of assisted ventilation for patients in cardiac arrest is more controversial. 3-3 Hurricane Season Preparation Annually, at the beginning of hurricane season (June 1), the H-EOT, the Office of Licensing , R-EOT, and The electric energy required to successfully cardiovert a patient from atrial fibrillation or atrial flutter to sinus rhythm varies and is generally less in patients with new-onset arrhythmia, thin body habitus, and when biphasic waveform shocks are delivered. Deterrence operations and surveillance. It consists of actions which are aimed at saving lives, reducing economic losses and alleviating suffering. It is not uncommon for chest compressions to be paused for rhythm detection and continue to be withheld while the defibrillator is charged and prepared for shock delivery. Studies on push-dose epinephrine for bradycardia specifically are lacking, although limited data support its use for hypotension. 5. Prompt systemic anticoagulation is generally indicated for patients with massive and submassive PE to prevent clot propagation and support endogenous clot dissolution over weeks. 1. Unauthorized use prohibited. In cardiac arrest secondary to anaphylaxis, standard resuscitative measures and immediate administration of epinephrine should take priority. It is feasible only at the onset of a hemodynamically significant arrhythmia in a cooperative, conscious patient who has ideally been previously instructed on its performance, and as a bridge to definitive care. Cardiac arrest survivors, their families, and families of nonsurvivors may be powerful advocates for community response to cardiac arrest and patient-centered outcomes. A well-organized team response when performing high-quality CPR includes ensuring that providers switch off performing compressions every _____ minutes. 4. Agonal breathing is described by lay rescuers with a variety of terms including, Protracted delays in CPR can occur when checking for a pulse at the outset of resuscitation efforts as well as between successive cycles of CPR. For lay rescuers trained in CPR using chest compressions and ventilation (rescue breaths), it is reasonable to provide ventilation (rescue breaths) in addition to chest compressions for the adult in OHCA. If possible, tell them what is burning or on fire (e.g. Currently marketed defibrillators use proprietary shock waveforms that differ in their electric characteristics. Because of potential interference with maternal resuscitation, fetal monitoring should not be undertaken during cardiac arrest in pregnancy. There are many alternative CPR techniques being used, and many are unproven. After identifying a cardiac arrest, a lone responder should activate the emergency response system first and immediately begin CPR. Some recommendations are directly relevant to lay rescuers who may or may not have received CPR training and who have little or no access to resuscitation equipment. For severe symptomatic bradycardia causing shock, if no IV or IO access is available, immediate transcutaneous pacing while access is being pursued may be undertaken. These include mechanical CPR, impedance threshold devices (ITD), active compression-decompression (ACD) CPR, and interposed abdominal compression CPR. Flumazenil, a specific benzodiazepine antagonist, restores consciousness, protective airway reflexes, and respiratory drive but can have significant side effects including seizures and arrhythmia.1 These risks are increased in patients with benzodiazepine dependence and with coingestion of cyclic antidepressant medications. The AHA has rigorous conflict of interest policies and procedures to minimize the risk of bias or improper influence during the development of guidelines. If this is not known, defibrillation at the maximal dose may be considered. These still require further testing and validation before routine use. Which term refers to clearly and rationally identifying the connection between information and actions? 4. 3. Commercially available defibrillators either provide fixed energy settings or allow for escalating energy settings; both approaches are highly effective in terminating VF/VT. The 2020 CoSTR recommends that seizures be treated when diagnosed in postarrest patients. More uniform definitions for status epilepticus, malignant EEG patterns, and other EEG patterns are Prevention Actions taken to avoid an incident. There is no evidence that cricoid pressure facilitates ventilation or reduces the risk of aspiration in cardiac arrest patients. 2. 1. During a resuscitation, the team leader assigns team roles and tasks to each member. Which action should you perform first? 4. 3. We recommend TTM for adults who do not follow commands after ROSC from IHCA with initial shockable rhythm. A recent systematic review of 11 RCTs (overall moderate to low certainty of evidence) found no evidence of improved survival with good neurological outcome with mechanical CPR compared with manual CPR in either OHCA or IHCA.1 Given the perceived logistic advantages related to limited personnel and safety during patient transport, mechanical CPR remains popular among some providers and systems. When performed with other prognostic tests, it may be reasonable to consider bilaterally absent pupillary light reflex at 72 h or more after cardiac arrest to support the prognosis of poor neurological outcome in patients who remain comatose. The potential mechanisms of action of IV lipid emulsion include active shuttling of the local anesthetic drug away from the heart and brain, increased cardiac contractility, vasoconstriction, and cardioprotective effects.1, The reported incidence of LAST ranges from 0 to 2 per 1000 nerve blocks2 but appears to be decreasing as a result of increasing awareness of toxicity and improved techniques.1, This topic last received formal evidence review in 2015.6, Overdose of sodium channelblocking medications, such as TCAs and other drugs (eg, cocaine, flecainide, citalopram), can cause hypotension, dysrhythmia, and death by blockade of cardiac sodium channels, among other mechanisms. These features make adenosine relatively safe for treating a hemodynamically stable, regular, monomorphic wide-complex tachycardia of unknown type. This topic was last reviewed in 2010 and identified 2 randomized trials, interposed abdominal compression CPR performed by trained rescuers improved short-term survival. In the setting of head and neck trauma, lay rescuers should not use immobilization devices because their use by untrained rescuers may be harmful. In a recent meta-analysis of 7 published studies (33 795 patients), only 0.13% (95% CI, 0.03% 0.58%) of patients who fulfilled the BLS termination criteria survived to hospital discharge. 6. Cough CPR is described as a repetitive deep inspiration followed by a cough every few seconds before the loss of consciousness. Antidigoxin Fab antibodies should be administered to patients with severe cardiac glycoside toxicity. A. Identifying and treating early clinical deterioration B. Tap Emergency SOS. OT indicates occupational therapy; PT, physical therapy; PTSD, posttraumatic stress disorder; and SLP, speech-language pathologist, Severe accidental environmental hypothermia (body temperature less than 30C [86F]) causes marked decrease in both heart rate and respiratory rate and may make it difficult to determine if a patient is truly in cardiac arrest. You are working in an OB/GYN office when your patient, Mrs. Tribble, suddenly goes into cardiac arrest. AED indicates automated external defibrillator; and BLS, basic life support. life and property.

Neglect the mass and friction of all pulleys and determine the acceleration of each cylinder and the tensions T1T_1T1 and T2T_2T2 in the two cables. In some observational studies, improved outcomes have been noted in victims of cardiac arrest who received conventional CPR (compressions and ventilation) compared with those who received chest compressions only. This topic last received formal evidence review in 2010.3. A case series suggests that mouth-to-nose ventilation in adults is feasible, safe, and effective. How does this affect compressions and ventilations? When pacing attempts are not immediately successful, standard ACLS including CPR is indicated. When bradycardia occurs secondary to a pathological cause, it can lead to decreased cardiac output with resultant hypotension and tissue hypoperfusion. On CT, brain edema can be quantified as the GWR, defined as the ratio between the density (measured as Hounsfield units) of the gray matter and the white matter. We recommend that the absence of EEG reactivity within 72 h after arrest not be used alone to support a poor neurological prognosis. In an emergency, the individual can press a call button to signal for help. If advanced airway placement will interrupt chest compressions, providers may consider deferring insertion of the airway until the patient fails to respond to initial CPR and defibrillation attempts or obtains ROSC. Urgent support of airway, breathing, and circulation is essential in suspected anaphylactic reactions. A 12-lead ECG should be obtained as soon as feasible after ROSC to determine whether acute ST-segment elevation is present. Call Quietly is available in iOS 16.3 and later. 1. CPR duty cycle refers to the proportion of time spent in compression relative to the total time of the compression plus decompression cycle. Bilaterally absent N20 SSEP waves have been correlated with poor prognosis, but reliability of this modality is limited by requiring appropriate operator skills and care to avoid electric interference from muscle artifacts or from the ICU environment. 1. We recommend TTM for adults who do not follow commands after ROSC from IHCA with initial nonshockable rhythm. It is reasonable for a rescuer to use mouth-to-nose ventilation if ventilation through the victims mouth is impossible or impractical. When evaluated with other prognostic tests, the prognostic value of seizures in patients who remain comatose after cardiac arrest is uncertain. One important consideration is the selection of patients for ECPR and further research is needed to define patients who would most benefit from the intervention. Three different types of evidence reviews (systematic reviews, scoping reviews, and evidence updates) were used in the 2020 process. Prompt treatment of cardiac glycoside toxicity is imperative to prevent or treat life-threatening arrhythmias. AED indicates automated external defibrillator; ALS, advanced life support; BLS, basic life support; and CPR, cardiopulmonary resuscitation. 5. It can be beneficial for rescuers to avoid leaning on the chest between compressions to allow complete chest wall recoil for adults in cardiac arrest. Time to drug in IHCA is generally much shorter, and the effect of epinephrine on outcomes in the IHCA population may therefore be different. Case reports and at least 1 retrospective observational study have been published on survival after ECMO in patients presenting with refractory shock from -adrenergic blocker overdose. response. In 2013, a trial of over 900 patients compared TTM at 33C to 36C for patients with OHCA and any initial rhythm, excluding unwitnessed asystole, and found that 33C was not superior to 36C. No studies were found that specifically examined the use of ETCO. Lay rescuerCPR improves survival from cardiac arrest by 2- to 3-fold.1 The benefit of providing CPR to a patient in cardiac arrest outweighs any potential risk of providing chest compressions to someone who is unconscious but not in cardiac arrest. Are you performing all of the required ITM on your Emergency Power Supply System? Whether resumption of CPR immediately after shock might reinduce VF/VT is controversial.52-54 This potential concern has not been borne out by any evidence of worsened survival from such a strategy. A single shock strategy is reasonable in preference to stacked shocks for defibrillation in the setting of unmonitored cardiac arrest. These effects can also precipitate acute coronary syndrome and stroke. Providers should perform high-quality CPR and continuous left uterine displacement (LUD). 1. Julie S Snyder, Linda Lilley, Shelly Collins, Foundations for Population Health in Community and Public Health Nursing, BIOL 1407-007 Chapter 37: The Endocrine Syste, Constitutional Law: Federalism, Structure of. When providing rescue breaths, it may be reasonable to give 1 breath over 1 s, take a regular (not deep) breath, and give a second rescue breath over 1 s. 4. If no emergency medical services (EMS) or other trained personnel is on the scene, activate the 911 emergency system immediately. Which compression depth is appropriate for this patient? Postcardiac arrest care is a critical component of the Chain of Survival and demands a comprehensive, structured, multidisciplinary system that requires consistent implementation for optimal patient outcomes. After cardiac arrest is recognized, the Chain of Survival continues with activation of the emergency response system and initiation of CPR. You are preparing to deliver ventilations to an adult patient experiencing respiratory arrest. The Adult Cardiovascular Life Support Writing Group included a diverse group of experts with backgrounds in emergency medicine, critical care, cardiology, toxicology, neurology, EMS, education, research, and public health, along with content experts, AHA staff, and the AHA senior science editors. Given the potential for the rapid development of oropharyngeal or laryngeal edema, immediate referral to a health professional with expertise in advanced airway placement, including surgical airway management, is recommended. Opioid-associated resuscitative emergencies are defined by the presence of cardiac arrest, respiratory arrest, or severe life-threatening instability (such as severe CNS or respiratory depression, hypotension, or cardiac arrhythmia) that is suspected to be due to opioid toxicity. In addition to defibrillation, several alternative electric and pseudoelectrical therapies have been explored as possible treatment options during cardiac arrest.
