8.3 Inspiration Hold
Inspiration Hold means to extend the patient’s time of inspiratory phase manually and to
prevent the patient from expiration for a certain period of time.
Push and hold the Insp. Hold key. The ventilator starts the Inspiration Hold function and the
screen shows [Insp. Hold Active]. Release the Insp. Hold key. The ventilator terminates the
Inspiration Hold function. Inspiration Hold is active for a maximum of 30 seconds. If the Insp.
Hold key is pushed and held for more than 30 seconds, the ventilator terminates the
Inspiration Hold function automatically.
During Inspiration Hold, the ventilator calculates Cstat and Pplat automatically and displays
the calculation results in the box as shown below.
NOTE
There is at least one expiratory phase between two inspiration holds.
The system responds to Insp. Hold key pressing operation only in non-standby
status.
Inspiration Hold function is disabled in CPAP mode and is supported when apnea
ventilation occurs.
8.4 Nebulizer
During nebulization, aerosolized medicament is inhaled by the patient for the purpose of
therapy.
Push the Nebulizer key and set the appropriate nebulization time. Select [Ok] to start
nebulization. When the nebulizer is started up, the nebulizer indicator lamp is illuminated and
the screen prompt message filed displays the remaining nebulization time.
When the set nebulization time expires or the Nebulizer key is pushed again, the ventilator
terminates nebulization.
NOTE
CO2 cannot be measured in the aerosolized medicament environment. CO2 module
sampling and monitoring are suspended when the nebulizer is started.
Nebulization is disabled in V-A/C, V-SIMV and PRVC modes when patient type is
pediatric.
Aerosolized medication may occlude the expiration valve and flow sensor. Please
have them checked and cleaned after nebulization.
