10. Perform Operational Test
Before attaching the patient to the ventilator, you should perform an Operational Test to ensure
that the breathing circuit is properly attached and that the primary patient safety alarms, such as
PATIENT DISCONNECT and AIRWAY PRESSURE HIGH are functioning properly.
To perform the operational test procedure, do the following:
a. Press the
Manual Breath
button; gas should flow out of the patient connection each time
the button is pressed.
b.
Close the patient port with a clean gloved hand. The HIGH AIRWAY PRESSURE LIMIT
alarm should activate after 2 breaths that reach the PIP High Limit.
If the AIRWAY PRESSURE HIGH alarm fails to activate, check to determine that all of the
circuit connections are secure, the exhalation valve is closing during inhalation, and that the
High Airway Pressure Limit is set to 35 cm H2O or less.
c.
After a breath or two, release the patient port while allowing the ventilator to operate. The
PATIENT DISCONNECT alarm should activate.
d.
Partially close the patient port to reset the PATIENT DISCONNECT alarm.
e.
With no other alarms occurring, remove external power from the ventilator. The
EXTERNAL POWER
LOW/DISCONNECT alarms should activate. Reconnect external power to reset alarms.
If either the HIGH AIRWAY PRESSURE, PATIENT DISCONNECT, or EXTERNAL
POWER LOW/DISCONNECT alarms fail to activate, continue to manually ventilate the
patient, check the patient circuit for leaks or a faulty exhalation valve and repeat the
Operational Test.
If operating using the internal battery, verify that the Battery icon indicates sufficient available
battery capacity remains to support the anticipated duration of operation. If not, begin
ventilation and find an alternate source of power.
Warning!
Until you have determined that the ventilator is functioning properly and that the
ventilator parameters are set correctly for the patient, do not connect the patient to the
ventilator.
11. Attach the Pulse Oximeter (Optional)
The pulse oximeter operates in all ventilator modes when its cable and sensor are properly
attached to the SpO
2
connector (during start up, the pulse oximeter is on standby -- the SpO
2
and HR parameter windows display
stby
).
To operate the pulse oximeter, connect the sensor to the patient and the cable to the SpO
2
connector on the top of the ventilator as shown in the Figure 3-7.
