Feedback:
If there is a normal mixture of oxygen and other gases in the environment, the oxygen analyzer will indicate 0.21 (21). An oxygen analyzer is a device that measures the percentage of delivered oxygen to determine whether the client is receiving the amount prescribed by the physician. The nurse or respiratory therapist first checks the percentage of oxygen in the room air with the analyzer. If there is a normal mixture of oxygen and other gases in the environment, the analyzer indicates 0.21 (21). When the analyzer is positioned near or within the device used to deliver oxygen, the reading should register at the prescribed amount (>0.21).
