Flowmeters


Case Synopsis

Anesthesia induction has just been completed on a healthy 20-year-old man undergoing inguinal herniorrhaphy. Gas flows are set to 1 L/min of oxygen (O 2 ) and 2 L/min of nitrous oxide (N 2 O). The O 2 saturation begins to fall as the O 2 analyzer alarms ( Fig. 110.1 ). Actuating the O 2 flush valve resolves the problem temporarily.

Fig. 110.1, The inspired oxygen concentration is dangerously low and is not consistent with the flowmeter settings.
