Instructions for Use Apollo SW 4.5n 145
Part Number: 9053586, 3rd edition
Continuous Positive Airway Pres-
sure CPAP - in Pressure Support
Mode (Optional)
The pressure support option on the Apollo is
enhanced with Continuous Positive Airway Pressure
(CPAP).
CPAP allows the patient to breath spontaneously on
an increased pressure level and therefore helps to
increase the functional residual capacity. It is
indicated for use only in patients who are breathing
spontaneously.
Continuous Positive Airway Pressure is activated in
Pressure Support when the value for the Pressure
Support ΔP
PS is set <= 2 cmH2O.
The apnea ventilation is not active during Pressure
Support CPAP. When CPAP is activated, the
minimum frequency Freq
MIN is set to OFF and the
rise time is set to 0.0.
Table 8. Adjustment ranges and factory settings for
CPAP
The parameters that can be set for CPAP mode are
shown in Table 8, along with their adjustment ranges
and factory default values.

2) Depending on the configuration, the inspiratory time (TINSP) can be
automatically changed together with adjustment of the frequency so that the
resultant ratio of inspiration to expiration (I : E) remains constant. Only
applies if trigger = OFF. See the chapter “Configuration”.
