Explanation of Modes, Breath Types and Special Functions
7
In A/CMV, all breaths delivered to the patient are delivered according
to the parameters set by the user. These are called mandatory
breaths. The user may choose to Pressure Control, Volume Control,
BiphasicPressureReleaseorVolumeTargetPressureControlthe
mandatory breaths. All breaths may be time (ventilator-triggered) or
patient-triggered.
The Resp Rate (respiratory rate) setting determines the minimum
number of time-triggered or patient triggered mandatory breaths
delivered each minute. The Trig setting determines the airway
pressure or airway flow threshold that the patient’s effort must reach
in order to trigger these and additional mandatory breaths.
If the patient doesn’t breathe or if the patient’s efforts don’t cause
airway pressure or airway flow to reach the Trig threshold, the e360
Ventilator delivers the number of time-triggered breaths each minute
selected via the Resp Rate setting.
