Clean patient circuit
1. Pull the patient circuit off the device and the exhalation system.
2. Pull out the one end of the pressure measuring tube
(shake a little if necessary) and seal it with the sealing
plug supplied. At the other end, seal the small opening
of the adapter using the second sealing plug so that
no water can penetrate.
3. Clean the creased tube with a little detergent in hot
water and make sure no residues are left behind. Flush
the inside of the tube through thoroughly in the
process.
4. Rinse the creased tube thoroughly inside and out using clean hot water.
5. Thoroughly shake out the patient circuit.
6. Hang up the patient circuit and leave to drip-dry well to stop moisture getting into the
therapy device.
7. Remove the plugs from the pressure-measurement tube.
