Warnings and Cautions
2.2 Preparing for
Ventilation
WARNING:
To ensure the correct performance of the ventilator and the accuracy of
patient data, we recommend you use only Respironics-approved accessories
with the ventilator.
WARNING:
To prevent possible asphyxia and to reduce the risk of CO
2
rebreathing, take
these precautions with respect to mask and exhalation port use:
•
Use only a mask with an exhalation port or a nasal mask for noninvasive
ventilation.
•
Do not occlude the exhalation port.
•
Turn on the ventilator and verify that the port is operational before
application. Pressurized gas from the ventilator should cause a
continuous flow of air to exhaust from the leak port, flushing exhaled gas
from the circuit.
WARNING:
Never leave the mask on the patient while the ventilator is not operating.
When the ventilator is not operating, the exhalation port does not allow
sufficient exhaust to eliminate CO
2
from the circuit. Substantial CO
2
rebreathing may occur.
WARNING:
To ensure normal air circulation and exchange, do not cover or block the
ports on the ventilator or ventilator circuit. Do not block the air inlet panel on
the right side of the ventilator.
WARNING:
To prevent possible patient injury and possible water damage to the ventilator,
make sure the humidifier is set to appropriate temperature and humidification
settings.
WARNING:
To prevent the possibility of inadequate humidification, pay close attention to
the humidifier’s functioning when operating the ventilator at an ambient
temperature > 30 ºC (86 ºF). The ventilator warms the air delivered to the
patient above ambient temperature, which may impair the humidifier’s
performance.
WARNING:
To reduce the risk that the patient will aspirate condensed water from the
breathing circuit, position any humidifier lower than both the ventilator and
the patient.
WARNING:
To prevent possible patient injury and equipment damage, do not turn the
humidifier on until the gas flow has started and is regulated. Starting the
heater or leaving it on without gas flow for prolonged periods may result in
heat build-up, causing a bolus of hot air to be delivered to the patient. Circuit
tubing may melt under these conditions. Turn the heater power switch off
before stopping gas flow.
WARNING:
To reduce the risk of fire, use only patient circuits intended for use in oxygen-
enriched environments. Do not use antistatic or electrically conductive
tubing.
WARNING:
To prevent patient or ventilator contamination, recommend you use a
Respironics-approved main flow bacteria filter on the patient gas outlet port.
Filters not approved by Respironics may degrade system performance.
