NOTE
Default value is configured in proportion to body weight of the patient.
The airway pressure is dependent on the tidal volume, inspiration time and the resistance
and compliance of the respiratory system. The set tidal volume will always be delivered.
An increase in the resistance and decrease in compliance will lead to an increased airway
pressure. To protect the patient’s lungs from excessive pressure, it is very important to
set the upper pressure limit to a suitable value.
It is possible for the patient to trigger extra breaths if they can overcome the pre-set
trigger sensitivity. It is also possible for the patient, by their own inspiratory efforts, to
receive a higher inspiratory flow and Tidal Volume during an inspiration than pre-set.
During volume control ventilation, peak flow is determined after configuration of tidal
volume and inspiratory time. Also in addition to the above two items, end flow and
plateau are items that influence peak flow.
Volume Control assures a preset tidal volume with constant flow during a preset
inspiratory time at a preset frequency.
When the preset tidal volume is delivered and after the preset pause time.
