2 Preparing for ventilation
If you do use an expiratory filter:
1. Place it on the patient side of the expiratory valve cover.
2. Remove any expiratory filter or HME during nebulization.
See the Warnings and Notes in this section for guidance.
3. You must monitor closely for increased expiratory circuit
resistance.
An
Exhalation obstructed
alarm can also indicate
excessive expiratory circuit resistance. If the
Exhalation
obstructed
alarm happens repeatedly, then remove the
expiratory filter immediately. If you suspect increased expira-
tory circuit resistance, remove the expiratory filter or install
a new filter to eliminate it as a potential cause.
2.10 Connecting to AC power
WARNING
• To minimize the risk of electrical shock, plug the
ventilator power cord into a grounded AC
power receptacle. It is the hospital’s responsi-
bility to ensure that the receptacle is properly
grounded (earth).
• To ensure grounding reliability, use a special
hospital-grade receptacle (USA only).
NOTE:
To prevent unintentional disconnection of the power
cord, make sure it is well seated into the ventilator’s
socket and secured with the power cord retaining clip.
Connect the device to a grounded AC outlet using power of
100 to 240 Volt, 50/60 Hz. Always verify the reliability of the
AC outlet. The AC power symbol in the bottom right-hand
corner of the screen is displayed with a frame around it. The
AC power LED on the ventilation unit will also be lit.
