Chain of Survival Flashcard 1

D. Rationale: Studies have shown that there are gaps for in-hospital resuscitation success rates. Poor survival rates have been recorded for resuscitations occuring during the weekends, holidays, and at nighttime.

B. Rationale: The telephone link represents the emergency response system, which is activated by the healthcare provider in cases of cardiac arrest or for critically ill patients. The emergency response system is a signaling device or communications system that alerts the resuscitation team to the scene.

B. Rationale: 20% of all OHCA occur in public areas with mass gatherings such as municipal buildings, airports, and schools. It is thus necessary to provide automated external defibrillators in these high-risk areas.

D. Rationale: Cardiac arrest is demanding to the body. After the successful resuscitation of a patient with an in-hospital cardiac arrest, patient survival rates decrease because of post-cardiac arrest syndrome. This syndrome is composed of anoxic brain injury, post-cardiac arrest myocardial dysfunction, systemic ischemic/reperfusion response, and persistent precipitating pathologies.

D. Rationale: For an in-hospital cardiac arrest, the team may consist of multiple healthcare providers such as nurses, respiratory therapists, doctors, and other specialists. (Systems of Care: IHCA)

C. Rationale: High-quality CPR is represented by the hands in the adult chain of survival. This involves providing chest compressions with a compression rate of 100–120/minute, with a compression depth of 2–2.4 inches, and allowing for chest recoil. Ventilation is given at a rate of 10 breaths/minute if the patient has an advanced airway or 2 breaths every 30 chest compressions.

D. Rationale: In out-of-hospital cardiac arrest, the team may consist of a bystander together with an emergency medical service provider.

D. Rationale: Rapid response teams and the medical emergency reams are the designated personnel responsible for in-hospital cardiac arrest patients. The multispecialty team is composed of physicians, nurses, and respiratory therapists. They must be available 24/7 and ready to be at the bedside as fast as possible.

B. Rationale: The Recovery link is the sixth link in the chains of survival. This link was added to emphasize the need for recovery steps prior to hospital discharge.

D. Rationale: In the pre-hospital setting or out-of-hospital cardiac arrest cases, lay rescuers are responsible for activating the emergency response system by calling 9-1-1 and performing immediate high-quality CPR and defibrillation if available.
