WARNING
Hoses and Accessories:
•
The ventilator must not use, nor be connected to, any anti-static or electrically conductive hoses,
tubing, or conduits. High and Low VTE alarm parameters must be properly set to warn in the event of
patient suffocation.
•
During invasive ventilation (when an artificial airway bypasses the patient’s upper respiratory system),
the patient’s upper respiratory system cannot humidify the incoming air. For this reason, the use of a
humidifier, to minimize drying of the patient’s airways and subsequent irritation and discomfort, must
be used.
•
If exhaled tidal volume or exhaled minute volume measurements are required to ensure correct patient
ventilation a double limb patient circuit configuration must be used in order to detect leaks. In this
case, both the High and Low VTE alarm parameters must be properly set to warn in the event of patient
suffocation.
•
The patient circuit should always be positioned to avoid hindering the patient's movements, to prevent
accidental disconnection, and to minimize the risk of patient strangulation.
•
For pediatric use, ensure that the patient circuit type fits, and, in all respects, is suitable for use with a
child. Use a pediatric circuit for patients that weigh under 53 lb. (23 kg). See Table E-2,
List of Circuits ,
on page E-2, for a list of recommended patient circuits.
•
Resistance of the exhalation valve and accessories (water traps, filters, and so on) must be as low as
possible.
•
Adding attachments to the ventilator breathing system can cause the pressure during exhalation at the
patient connection port to increase.
•
The exhalation valve must allow rapid discharge of the circuit pressure. Ensure that the exhalation
valve is always clean and its evacuation aperture (exhaust port) is never obstructed.
•
Users must always possess an additional breathing circuit and exhalation valve while using the Puritan
Bennett 540™ Ventilator.
•
Consult with your Customer Support representative before attempting to use a heated humidifier.
•
Always position a humidification device so that it is lower than both the ventilator and the patient. Use
water traps, if necessary, to limit water in the patient circuit and periodically empty these water traps.
•
If a heated humidifier is used, you should always monitor the temperature of the air delivered to the
patient. Air delivered from the ventilator that becomes too hot may burn the patient's airway.
•
Adding accessories to the ventilator breathing circuit, such as a humidifier and water trap(s), may result
in a decrease in tidal volume delivered to the patient due to the added compressible volume of the
accessory. Always assure that the patient is receiving the appropriate inspired volume when altering
the breathing circuit configuration.
•
The level of inspiratory resistance of the circuit and accessories (bacteria filter, humidifier, and so on)
must be as low as possible. Settings—particularly the LOW PRESSURE DISCONNECT alarm, High
inspired volume (High VTI), and Low inspired volume (Low VTI) settings—must be periodically
adjusted according to changes in the patient circuit resistance—especially when filters are replaced.
•
To ensure proper performance of the ventilator, use a patient circuit recommended by Puritan Bennett
in this manual; refer to chapter
4, “Installation and Assembly” . The total specified length of the patient
circuit tubing as measured from the ventilator outlet to the ventilator inlet is 3.6 feet (1.10 meters) to
6.6 feet (2.00 meters).
The tubing must conform to all applicable standards and must be fitted with Ø 22 mm terminals that
also conform to all applicable standards. Ensure that both the length and the internal volume of the
patient circuit are appropriate for the tidal volume: a corrugated tube of Ø 22 mm for adult patients,
and a corrugated tube of Ø 15 mm for pediatric patients with a tidal volume lower than 200 ml.
•
When using non-invasive ventilation (niv), use a non-vented nose or face mask.
•
Before using the Nurse Call system, ensure that its connections are secure and it operates properly. For
more information, contact Puritan Bennett.
