Adequacy of circulation should be monitored by the continuous display of the ECG, & by determining the arterial BP & HR at least at 5-min intervals. Capnography ETCO2 analysis during GA When using a vent, there should be a device that is able to detect a disconnection of any part of the breathing system. Ensure correct placement of ETTs/LMAs requires clinical assessment & qualitative identification of CO2 in the expired gas.

Quantitative monitoring of TV & capnography When administering regional anesthesia or MAC, sufficient ventilation should be assessed by qualitative clinical signs &/or monitoring of exhaled CO2. 02 analyzers w/ low concentration-limit alarms during GA Quantitatively assessing blood oxygenation Continuously ensuring the adequacy of ventilation by physical diagnostic techniques Identification of expired CO2 is performed unless nullified by the type of pt, procedure, or equipment.
