Q

In cardiac arrests without hypoxic causes (e.g., suffocation, drowning), oxygen content in the lungs at the time of cardiac arrest is usually sufficient for maintaining acceptable arterial oxygen content during the first several minutes of CPR.

Q

Compression-­ only CPR is easy for an untrained rescuer to perform and can be more effectively guided by dispatchers over the telephone. (…) However, for the trained lay rescuer who is able, the recommendation remains for the rescuer to perform both compressions and breaths, especially for victims with asphyxiation causes of cardiac arrest or prolonged CPR.

Q

Physiologically, in most cases of SCA, the need for assisted ventilation is a lower priority because of:

A
  • Availability of adequate arterial oxygen content at the
    time of an SCA.

The presence of this oxygen and its renewal through gasping and chest compressions (provided there is a patent airway) also supported the use of compression-only CPR and the use of passive oxygen delivery.
