4.1.4. Connecting the Patient Circuit
1.
Attach the O-Two patient circuit (Figure 03) to the 22mm gas
output connector (S) (Figure 02).
2. Connect the sensing hoses (V) (Figure 03) of the patient circuit
to their corresponding connectors (Q) & (R) (Figure 02).
3. Attach a face mask to the patient port of the patient circuit. For
invasive ventilation, attach an endotracheal tube (ETT) instead.
The size of ETT shall be appropriate for the intended patients.
It is recommended to use ETT with no cuff for infant patients.
DO NOT connect the patient circuit to a patient or attach the test
lung until the ventilator is turned on (Step 4.1.5) and three solid
silhouettes start up figures (Figure 06) are displayed.
4.1.5. Turning the Ventilator ON
To turn on the ventilator, Press the ON/OFF key (N) (Figure 01) for
one second. During that second the associated green LED will start
blinking at a high frequency. After 1 second the ventilator will turn
on but with no ventilation at this point.
If the key is pressed and released for less than one second, the
ventilator will remain OFF.
Note: Do not connect the patient circuit to a patient or the test lung
before turning on the ventilator. SIMV is the default start-up ventilation
mode for e500.
4.2. Pre-use Checks
The following checks must be performed and confirmed by the
healthcare provider in the following cases:
•
Prior to use
•
After replacing hoses, patient circuits or batteries
•
At least every 6 months.
