respiratory arrest question?

FACAS L,

Respiratory arrest is the term used to indicate cessation of breathing. The major deleterious effect of respiratory arrest is the nearly immediate brain damage that is caused from lack of oxygen. When a person's breathing stops, they rapidly begin to deplete the oxygen stored in their bloodstream. Even if their heart continues to beat, the blood it is circulating steadily loses oxygen. Eventually this will lead to brain damage, cardiac arrest and death. Listening through a stethoscope (auscultation) may reveal abnormal breath sounds, irregular heart rhythm, and lack of bowel sounds in the abdomen. A neurological exam may indicate impaired sensory and motor function. If the individual is suffering from ventilation fatigue, the chest may heave when breathing, indicating overworking of the ventilatory muscles. ECG/EKG readings differ according to the cause of the cardiac irregularities. For instance, with an infarction, small, normal Q waves can be seen in lateral leads (I, aVL, V4 to V6), while moderate-large sized Q waves may be normal in leads III, aVF, aVL, and V1. When Left atrial enlargement is noted, P waves are notched (M-shaped) in I, II, or aVL or a deep terminal negative component to P in V1. In contrast, when Right atrial enlargement is noted, tall, peaked P waves (> 2.5 mm)are seen in II, III, aV.
