Monitoring of Additional breathing parameters

2-26
•
Based on the lung ventilator parameters set by the User and on the
patient's characteristics, the lung ventilator is able to monitor and
measure a series of values necessary for the patient's clinical
evaluation.
•
The measured and monitored values (right side of the screen) are
updated after each breath of the patient.
E.g. Here below the data in the images below refer to VC/VAC operative
mode.
Static compliance
It is one of the parameters of the lung mechanics: measured in
ml/cmH O, represents the lung compliance when the patient does
2
not breathe.
You can use it to asses the lung elasticity: the higher the
compliance, the more elastic the "lung"; the lower the compliance,
the more "rigid" the lung.
The static compliance can be calculated using the formula below:
Cs = current inspired volume / pause pressure.
Dynamic compliance
It is one of the parameters of the lung mechanics: measured in
ml/cmH O, represents the lung compliance either during the
2
inspiration or during the expiration.
You can use it to asses the lung elasticity: the higher the
compliance, the more elastic the "lung"; the lower the compliance,
the more "rigid" the lung. The dynamic compliance can be
calculated using the formula below:
Cd = current inspired volume / peak pressure
