data used for detecting a blood-gas machine that is out of control
the + or - 2 standard deviation
how would you correct an out of control situation for a blood gas analyzer
replace electrode that displays the out of control error
to measure px’s MIP what instruments should be selected to obtain the measurement:
pressure manometer
when measuring VE using wright spirometer:
the number of breaths taken by the px should be counted during the measuring period
