WARNING
Pressing this button will alter the respiratory cycle while the measurements are being
taken. Patient respiration may be impeded.
This function allows you to measure the patient's physiological respiratory characteristics:
resistance, compliance, and intrinsic pressure.
The ventilator delivers a square flow cycle with a 2.0 second end-inspiratory pause and a 0.5
second end-expiratory pause.
The formulae used to calculate the resistance and compliance are:
•
R = (Pmax – Pplat) /
•
Cstat = V
where:
•
PEEPtot = PEEPi + PEEP (before the end-expiratory pause).
