Theory of Operation The Breathing System
1.9 The Breathing System
1.9.1 CMV mode, inspiration
Tidal volume (T Vol.) compensates for variations in gas flow. This is to ensure that the set tidal
volume is delivered to the patient.
FIGURE 1-28 Breathing System Pneumatics, CMV Mode, Inspiration
1.9.2 CMV mode, expiration
As the patient exhales tidal volume into the expiratory limb, fresh gas enters the bellows.
Fresh gas mixes with exhaled gas after the Absorber removes CO
2
. Excess fresh gas passes
through the exhaust valve to the AGSS
