Installing The Patient Circuit - Respironics V60 User Manual

Installing the patient
circuit
WARNING: To reduce the risk of strangulation from patient tubing, use a tubing
support arm and secure the proximal pressure line with clips.
WARNING: To prevent possible patient injury and possible water damage to the
ventilator, make sure the humidifier is set appropriately.
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 that the patient will aspirate condensed water from the
breathing circuit, position any humidifier lower than both the ventilator
and the patient.
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, always use a main flow
bacteria filter on the patient gas outlet port. Filters not approved by
Respironics may degrade system performance.
WARNING: During ventilation, patient exhalate is released into room air. Use of a
patient circuit with a filter on its exhalation port is recommended.
WARNING: To reduce the risk of bacterial contamination or damage, handle bacteria
filters with care.
WARNING: Avoid adding any components to the patient circuit that are not absolutely
necessary. Additional components installed in the patient circuit can
change the pressure gradient across the ventilator breathing system,
increase the dead space, and adversely affect the ventilator performance.
WARNING: Any additional accessories in the patient circuit may substantially
increase flow resistance and impair ventilation.
WARNING: Avoid adding resistive circuit components on the patient side of the
proximal pressure line. Such components may defeat the disconnect
alarm.
WARNING: Using a jet nebulizer can cause inadvertent alarms and affect the
accuracy of delivered FiO2. To reduce patient risk, use only an approved
nebulizer.
NOTE: Bacteria filter must be installed onto gas outlet.
NOTE: Resistive components can include but are not limited to HMEs,
proximal flow sensors, a filter at the patient connection, or a narrow
diameter circuit attached to a mask.
NOTE: Under extreme conditions and a missing, ruptured, or defective
bacteria filter, the entire gas pathway can become contaminated with
bodily fluids or exhaled gas.
Install the patient circuit as shown in this section. For a list of compatible
parts and accessories offered by Philips, see "Parts and accessories" on
