o2 consumption in kids v adults - ANSWER kids 6-8ml/kg compared to 3-4 ml/kg in adults
what is hypoxemia - ANSWER decreased arterial oxygen sat detected by pulse ox or direct measuremnt
of o2 sat in an abg
so you want their oxygen level at least - ANSWER 94
hypoxia v hypoxemia - ANSWER hypoxemia is low blood o2 sat, hypoxia is pathologic odnition in which
body as a whole or region of body is deprived of adequate oxygen
you can be hypoxic without hypoxemia
you can have hypoxemia without hypoxia
