Mouth-to-nose respiration:
breather steadily and smoothly
into the patient's mouth, filling his
or her chest with air.
Fig.15-7
Mouth-to-nose respiration: lift
your mouth away so that the
patient can breathe out; watch
for the chest falling, feel for the
patient's breath on your cheek,

patient's mouth (or nose) again. Watch the patient breathe out again. Then

back and clear the airway again. Make sure there is no air escaping when you
breathe into the patient's mouth (or nose).
15.1.2 Cardiac arrest
Cardiac arrest signs and symptoms
Cardiac arrest is classified into "shockable" versus "non–shockable",
based upon the ECG rhythm. The two shockable rhythms are ventricular
fibrillation and pulseless ventricular tachycardia while the two non–shockable
