DMR V4C 3.3 (User Manual) V-4 06-May-2022
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:
Never obstruct the air intake port or vents for any reason.
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.
WARNING:
If at any time it is observed that excessive and consistent gas is exiting through the vents at the
back of the Oxygen Mixer, call for maintenance.
WARNING:
If at any time a leak is suspected from or inside the V4C-O2E Oxygen Mixer, terminate use and call
for maintenance. Excessive oxygen consumption may be indicative of a leak.
