To Turn the Ventilator On (cont.)
If the Power On Self Tests are passed successfully, the ventilator starts operation using the stored
control settings, with the following exceptions;
• To prevent nuisance alarms, the LOW MIN VOL alarm (Low Minute Volume) is suspended for
the first 20 seconds and the HIGH f alarm (High Breath Rate) is suspended for the first 60
seconds of operation.
If the Power On Self Tests fail, the mode of failure (CPU, SRAM, INT VECTOR, ROM CRC or
EEPROM) is displayed in the message window and an audible alarm sounds continuously.
• Turn the ventilator off by pushing the On / Standby button.
• Silence the alarm by pushing the Silence / Reset button.
• Discontinue use of the ventilator and immediately contact a certified Pulmonetic Systems’
service technician or Pulmonetic Systems.
Before Connecting the Ventilator to a Patient
Perform the following steps before connecting the ventilator to a patient:
1) If this is the initial use of the ventilator, follow the checkout procedures in Appendix C -
Installation and Checkout before proceeding.
2) If desired, you may connect the ventilator to a Patient Assist Call system. See Appendix C -
Installation and Checkout for details.
3) If required, connect a low or high pressure oxygen source to the ventilator. If you connect a low
pressure oxygen source, make sure to select the Low Pressure O
2
Source option on the front
panel. See Appendix C - Installation and Checkout for connection and setup details.
WARNING
Inspired Oxygen (FIO
2
) Concentration – If the patient has a variable respiratory rate, his/her minute
ventilation will fluctuate. If exact concentrations of inspired oxygen (FIO
2
) are required to be delivered
to the patient, it is recommended that an accurate oxygen analyzer with alarms be used.
AVERTISSEMENT
Concentration d’oxygène inspiré (FIO
2
) – Si la fréquence respiratoire du patient est variable, sa
ventilation-minute va fluctuer. Lorsqu’une concentration exacte d’oxygène inspiré (FIO
2
) est
nécessaire pour une transmission au patient, il est recommandé d’utiliser un analyseur de niveau
d’oxygène précis, comportant des alarmes.
