II.2. Daily disinfection
Because there is a final product filter inside the device, daily
disinfection concerns only the external oxygen therapy
accessories: humidifier, probes, nasal cannulas (refer to the
respective instructions for use).
The device must be switched off when alcohol based so-
lutions are used.
a. The following minimum guidelines must be
observed:
•
Humidifier : (If prescribed by a physician)
Clean according to the manufacturer's instructions. If no
instructions are provided, do the following:
Daily:
• Empty the water from the humidifier.
• Rinse the humidifier flask under running water.
• Fill humidifier up to the mark with distilled water.
Regularly:
• Disinfect the humidifier parts by immersing them in a
disinfectant solution (In general, we recommend using a
solution of 1 part vinegar diluted with 10 parts water).
• Rinse and dry.
• Check that the humidifier lid seal is in good condition.
•
Oxygen tubing and nasal cannula:
Follow the manufacturer’s instructions.
b. For each new patient:
Follow the instructions from the humidifier manufacturer.
The
Mark 5 Nuvo MB
must be cleaned and disinfected as
per the above instructions. The cabinet air filter should be
washed or replaced. The entire oxygen administration circuit
(oxygen therapy nasal cannulas, etc.) must be changed.
III.3. Maintenance
No special maintenance needs to be carried out by the
patient
. Your equipment supplier performs periodic main
