68
Preanesthesia check for offsite/mri
Emergency backup power to ensure pt protection for unforeseen circumstances. 10) Adequate means to illuminate the pt, anes machine, and monit equip. 13) If you're giving gas, have equip to monitor everything just like in the OR

90
Measured temps highest to lowest(excl axillary and forehead)
Rectal-Bladder. Everything else is about the same
91

97
Measures heat dissipation
heated wire anemometer
98
Measures pressure gradient
pseumotachometer
99
All ventilators display what 3 things
volume, rate, and MV
100
where to place pressure flow sensors
B&D on picture, both inspiratory and exiratory limbs
101
why respirometer on expiratory limb?
So you can detect a disconnect early, even a ett leak
102
Why place respirometer in positions A&B on exp limb?
So you can detect reverse flow and a malfunction unidirectional valve
103
Pressure control flow volume loop shape
parallelogram
