DMR V4C 3.3 (User Manual) V-4 06-May-2022
2 Overview
WARNING:
Always read and follow all instructions and labelling of the compatible ventilator when using the
V4C-O2E Oxygen Mixer. Ensure all warnings included in the manual of the compatible ventilator
are read and understood prior to use with the V4C-O2E Oxygen Mixer.
WARNING:
While the ventilator is in use, an alternative means of ventilation should always be available in
the event of a ventilator problem. This is particularly true for ventilator-dependent patients.
Supplementary observation, appropriate for the patient's condition, is also recommended.
WARNING:
Only use the V4C-O2E Oxygen Mixer with compatible ventilators listed in Section 2.4,
Compatible Ventilators and marked with an O2E port. Do not attempt to use the Oxygen Mixer
with other ventilators.
WARNING:
This V4C-O2E Oxygen Mixer must be used only under the responsibility and on the prescription
of a doctor.
WARNING:
Ventilator-dependent patients should always be monitored by trained and competent medical
personnel. Patients should be regularly checked to ensure that the oxygen concentration
settings match with the patient condition.
WARNING:
This manual tells you how to respond to and troubleshoot issues with the V4C-O2E Oxygen
Mixer, but it does NOT tell you how to respond to the patient. Always examine the patient first
before examining the ventilator and Oxygen Mixer.
WARNING:
Improper use of the V4C-O2E Oxygen Mixer, failure of the device, or failure to deliver oxygen can
result in patient injury or death. Always follow instructions in this manual and that of the
compatible ventilator, and always monitor the patient.
