Mechanical Ventilation May Not Be Essential for Initial Cardiopulmonary Resuscitation

Rescuer Fatigue in the Elderly: Standard vs. Hands-only CPR

“…Studies have shown that HO-CPR delivers substantially more chest compressions per minute, and is easier to remember and perform than standard CPR (10)(11)(12)(13). Animal and clinical investigations show that HO-CPR is at least as good as STD-CPR in terms of survival and neurologic outcome (4,(14)(15)(16)(17)(18)(19)(20)(21). Perhaps most importantly, bystanders are more likely to provide HO-CPR than STD-CPR for a variety of reasons, including fear of mouth-to-mouth disease transmission (10,(22)(23)(24)(25)(26).…”

Chest compressions versus ventilation plus chest compressions: a randomized trial in a pediatric asphyxial cardiac arrest animal model

“…Moreover, some experimental studies of CA secondary to ventricular fibrillation have found a similar rate of recovery and a better neurological prognosis in animals that received chest compressions only (CC) in comparison with those that were resuscitated with the standard technique of ventilation plus chest compressions (VC) [6][7][8][9][10][11]. With CC resuscitation, the absence of interruptions of chest compressions would optimize the perfusion of vital organs and hyperventilation would be avoided.…”

Effects of Bag-mask versus Advanced Airway Ventilation for Patients Undergoing Prolonged Cardiopulmonary Resuscitation in Pre-hospital Setting

“…However, there is some controversy regarding the relative effectiveness of this type of CPR vs. the effectiveness of CPR advanced airway ventilation performed by health care providers (11)(12)(13). Measured minute ventilation and arterial oxygenation decrease after 4-10 min of resuscitation, regardless of attempts at ventilation (14)(15)(16). Several studies suggest that ventilation is not essential during the initial 12 min of resuscitation if untreated arrest intervals are < 6 min (13,16,17).…”
