Figure 3-3 Fresh Gas/Emergency Air Intake
Warning!
Never block the Fresh Gas/ Emergency Air Intake, free flow of air is required during
compressor operation or in the event of device failure to allow spontaneous breathing.
The Fresh Gas/Emergency Air Intake also acts as an anti-asphyxia port in the event of a
ventilator failure.
4. Connect Fresh Gas/Emergency Air Intake Attachments
(Optional)
The operating environment of the ventilator may require you to connect the following
attachments to the Fresh Gas/Emergency Air Intake:
3-Liter Reservoir Bag Assembly
If the ventilator will use oxygen from low-flow sources, you may choose to attach an Oxygen
Reservoir Bag Assembly. Follow these steps:
1. Press the
Menu
button and use the
Dial
to choose O
2
Reservoir "On". This tells the
ventilator that the reservoir is attached and prevents the FRESH GAS INTAKE
RESTRICTED alarm from sounding.
2.
Attach the Oxygen Reservoir Bag Assembly to the Fresh Gas/Emergency Air Intake. This
port is located in the side of the ventilator. It will be necessary to use the supplied 22 mm
male-to-male adapter with 731 Series Ventilators.
3.
Connect the O
2
supply tubing between the O
2
source and the hose barb on the Reservoir Kit.
4.
Adjust the O
2
flow to achieve an acceptable O
2
saturation.
Note:
The assembly will function when the reservoir bag is hanging down or lying
horizontally provided the bag does not fall in such a way that occludes the neck of the
bag. The ventilator will sound a Low Priority FRESH GAS INTAKE RESTRICTED
Alarm if the menu has not been changed (see "1"above). Operating with the alarm
active does not affect the ability of the ventilator to deliver breaths at the current
settings. It is to alert the user that a restriction has been detected at the inlet.
Always allow 5 to 10 minutes between adjustments to assure the patient oxygenation
has stabilized. This is very important when decreasing the O
2
supply where it may take
several minutes for a patient to stabilize at the new O
2
flow.
