ad 1) Calculate the minute ventilation according to the relation (6.1):
(6.1)
and the alveolar ventilation according to the relation (6.2):
(6.2)
where
V
M
is minute ventilation, V
t
is tidal volume, f is breathing frequency, V
A
is alveolar
ventilation and
V
D
is anatomical dead space (approx. 160 ml for an adult person). Record the
calculated values in Tab. 6.1.
Tab. 6.1: Values of minute and alveolar ventilation for different combinations of breathing
volume and breathing frequency.
Before the actual measurement, become acquainted with the Veolar ventilator on
which the measurement will take place.
Ventilation parameters
Front panel of the Veolar ventilator is divided into three basic parts: controlling
(“Control” panel), monitoring (“Patient Monitor”) and the part with alarms (“Alarm” panel).
The controlling part (Fig. 6.2) is used for setting up parameters determining the character of
the actual ventilation.
