Ventilation Parameters
This panel shows five parameters
which are calculated or measured and
displayed by the CCV. These are
updated in real time, breath to breath.
Measurements include the following:
I:E Ratio is the ratio of inspiration time to expiration time. The ratio is
always expressed as 1:Y where Y is the expiration value. Thus, when the
illuminated display shows 2.0, the I:E ratio is 1:2, and the expiration time
is twice as long as the inspiration time. The ratio is determined by the
clinician’s choice of inspiration time and respiratory rate.
Flow is the flow rate in liters per minute delivered during inspiration in
Volume AC and Volume SIMV. It is not the same as minute volume.
PIP shows the airway pressure measured in the patient circuit near the
connection to the endotracheal tube or mask. This value will change
during the course of a breath, and the maximum value achieved during
the breath (the Peak Inspiratory Pressure) will be displayed for half a
second at the end of the breath.
Delivered Tidal Volume is measured in the CCV and represents the
volume of oxygen and air that entered the patient circuit during the
breath.
Spontaneous BPM is the number of spontaneous breaths taken in the
last minute based on the trigger sensitivity set by the clinician.
Each time a patient takes a spontaneous breath, the green indicator
light will flash and the breath will be added to the running one-minute
total.
