2.4 Usage of Patient Circuit
WARNING!
The ventilator supports leakage circuits, circuits with an active exhalation valve and
circuits with mouthpiece interface. Failure to use a mask or accessory that minimizes
rebreathing of carbon dioxide or permits spontaneous breathing can cause
asphyxiation.
For the ventilator to deliver treatment according to settings, it is important that the
selection of the patient circuit type is correctly set.
Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Before use:
• Make sure that the patient circuit and joined parts are undamaged and correctly
connected, in order to avoid unwanted leakage.
• For leakage circuits: Make sure that the leakage port of the circuit or mask is not
blocked or obstructed. This port prevents rebreathing by flushing the exhaled air.
• For active exhalation valve circuits: Check the function of the exhalation valve and
that it is not blocked or obstructed.
• The Vivo 45 LS should be turned on and the function of the leakage port should
be checked before use: The pressurized air from the Vivo 45 LS causes a continu-
ous flow of air through the leakage port, enabling flushing of exhaled air.
Risk of Suffocation
If the patient needs assistance to remove the patient interface, the patient shall not
be left alone. This is to avoid the risk of re-breathing of CO
2
in case of accidental
ventilator failure.
Do not breathe through the connected patient circuit unless the ventilator is turned
on and operating properly.
WARNING!
Risk of Electric Shock
Do not use antistatic or electrically conductive hoses or tubing with the ventilator
breathing system. This could result in electrical shock.
WARNING!
Always use a new patient circuit when the ventilator is to be used by a new patient.
