Patient Circuit; Figure 4-6. Connecting The Dc Power Cable To The Ventilator - Covidien Puritan Bennett 540 User Manual

Installation and Assembly
To connect the DC power cable to the ventilator, proceed as follows:
1. Line up the red marker dot on the ventilator's DC power connector with the marker on the DC
power cable
Align the red markers

Patient Circuit

WARNING
•
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).
•
If exhaled volume monitoring is required (such as ventilator dependant patients), use the double-limb
circuit for exhaled tidal volume or minute volume monitoring. In this configuration, the expired volume
is monitored to ensure correct patient ventilation and identify any leaks or other problems in the
patient circuit. Similarly, the Low VTE setting must be properly set to warn in the event of patient
suffocation.
•
The ventilator and patient circuit should always be placed so as not to hinder the patient's movements,
prevent accidental disconnection, and reduce the risk of patient strangulation by the circuit.
•
The ventilator and patient circuit should always be placed so as to provide a secure, comfortable
fit for the patient.
•
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.
