OPERATING PROCEDURE

The following paragraphs provide detailed instructions for operating the IC-2A ventilator
in the following modes:
a. IPPV
b. SIMV
c. CPAP
d. Manual
Operation of the Ventilator requires that various controls (figure 1-1) be set for time and
flow. Figures 3-1 and 3-2 provide time and flow settings for various volumes,
respiratory rate, and the I/E ratio requirements.
In Figure 3-1, respiratory rate is the result of 60 divided by the sum of the inspiratory
and expiratory times:
RESPIRATORY RATE =
Tidal volume (expressed in milliliters) is the product of inspiratory time (seconds) and
flow rate (milliliters per second):
TIDAL VOLUME (ml) = INSPIRATORY TIME (sec) X FLOW RATE (ml/sec)
Figures 3-1 and 3-2 are printed on the side of the IC-2A for the convenience of
operating personnel.
