Figure 10-3 • Volume control diagram
Volume control supplies a set tidal volume. The ventilator calculates a
flow based on the set tidal volume and the length of the inspiratory
time from the I:E and respiratory rate settings. An optional inspiratory
pause can be set to improve gas distribution in the lungs.
A typical volume-controlled pressure waveform increases throughout
the entire inspiratory period and rapidly decreases at the start of
expiration.
The ventilator adjusts gas flow to the bellows based on measured
inspiratory volumes. This is called tidal volume compensation.
Volume control settings include:
•
TV - sets the amount of tidal volume.
• RR - sets the rate of mechanically driven breaths.
• I:E - sets the amount of inspiration to expiration ratio.
• Pmax - sets the maximum airway pressure.
• Tpause - sets the inspiratory pause time.
