Breas Vivo 45 LS User Manual page 27

Patient connected parts and all filters must be replaced regularly to ensure correct
function of the ventilator. All replaced parts must be disposed of according to local
environmental regulations regarding the disposal of used equipment and parts.
Patient circuits used with the ventilator shall have the following characteristics:
•
•
•
If an active exhalation valve is used:
•
•
By conducting a pre-use test (see4.7 Performing the Pre-use Test, page 52) the compati-
bility of the complete patient circuit configuration with the ventilator can be verified.
If a pre-use test is successfully performed the circuit configuration meets the
required characteristics.
Always perform a pre-use test when the patient circuit is replaced or modified. Also
check the alarm settings as changes to the patient circuit may affect the alarm
triggering.
Risk of Suffocation
Periodically check for moisture in the patient circuit.
When present, remove the moisture. Before attempting to dry the circuit, disconnect
it from the Vivo 45 LS to ensure no water flows back into the Vivo 45 LS.
The frequency at which these checks must be performed will depend on the patient's
condition and the device used. The responsible caregiver should assess this on an
individual basis in accordance with the patient's needs.
The leakage from the mask or leakage port should be at least 12 l/min at 4 cmH
to prevent rebreathing of exhaled air. The recommended leakage is 20 to 50 l/min at
10 cmH
When using the ventilator invasively, the low volume alarm and the low breath rate
alarm must be carefully set, to ensure safe use.
