deliver means of positive pressure ventilation
Gas machine 3rd purpose
deliver anesthetic gas to pt
Key safety features for AGMs
BATTERY BACKUP, alarms, monitors, flow meter controls
MOST IMPORTANT key safety feature
BATTERY BACKUP ~30mins
Oxygen’s 5 Tasks ( gas machine purpose founded on this)
-ventilator driving gas
-flush valve
-O2 pressure fail alarm
-O2 pressure sensor shut off valve (fail safe)
-drive flowmeters
_ - _ _ measures amount of potent inhaled anesthetic agent to be added
concentration-calibrated vaporizer
_ deliver a controlled gas mixture in terms of concentration of o2 and other gases and total gas flow rates via gas flow controls
Flowmeters
Fresh gas mixture of known composition and metered production leaves anesthesia machine at :
CGO
The _ _ is a minienvironment that allows respiratory exchange and control of anesthetic and respiratory gas tensions
Patient Circuit
Anesthesia ventilator _ or _ may be connected to breathing circuit to provide mechanical ventilation
bellows or pistons
Excess gases are vented from breathing circuit and at end-exhalation when not using a ventilator via the _ _
APL valve
Excess gases are vented from breathing circuit and at end-exhalation when using a ventilator via the ventilator _ _ valve
ventilator pressure relief valve
