Processing

Ball

Nitrous oxide is a hypoxic gas mixture; oxygen and air can support life

Can produce carbon monoxide in the presence of desflurane

50 psi

Replace all downstream gases with oxygen

Spill valve

Expiratory time

Turn on the oxygen cylinder then disconnect the pipeline oxygen supply

Common gas outlets
Flowmeters
Vaporizers

Ensure that the fresh gas flow meets or exceeds the patient’s alveolar ventilation

Read the manufacturer’s operating manual

During leaky mask ventilation when breathing bag is empty
To rapidly remove anesthetic agent from circuit

An increased lung compliance results in a larger tidal volume

Calcium hydroxide

Viscosity

0.80

2 ppm

Adjustable pressure limit valve
Ventilator spill valve

Nitrous oxide

A leak in the bellows can cause barotrauma
The direction of bellows movement during inspiration governs the bellows classification

Negative circuit pressure allows ambient air to enter the breathing circuit
