2.6 Invasive Use — Warnings and Precautions
WARNING!
Risk of Faulty Treatment
If using the Vivo 3 for invasive ventilation, humidification is recommended. Make sure
to use an external heated humidifier that complies to invasive use according to ISO
80601-2-74.
The attachable humidifier is not intended for invasive use.
Risk of Unnoticed Critical Conditions
When using the Vivo 3 invasively, physiological alarms, such as the low volume alarm
and the low breath rate alarm, must be carefully set, to ensure safe use.
Risk of Rebreathing
Be aware of risks for rebreathing exhaled gases:
•
•
•
The Vivo 3 is equipped with a low leakage alarm. However, the alarm is not a substitute
for operator vigilance for ensuring that the leakage ports remains clear at all times.
Periodically check the leakage ports during therapy.
See the section 2.4 Patient Circuit — Warnings and Precautions, page 13 for mitigating the
risks of rebreathing.
2.7 Humidification and Heating — Warnings and Precautions
WARNING!
Risk of Personal Injury
The attachable humidifier shall not be used with nitric oxide. Such use might cause the
humidifier to not function correctly, causing serious deterioration of health.
Risk of Suffocation
When the attachable humidifier is installed, the Vivo 3 must be located below the patient
and on a flat surface. This is to prevent personal injury from accidental spillage or from
excess water or condensation flowing down the patient tube and into the patient's mask.
Extra cautions should be taken for patients who are unable to guard their airways or can-
not pull off the mask.
Risk of Suffocation or Loss of Ventilation
Incorrect placing of the ventilator may cause transient hypoxia.
If using an external humidifier, it shall be placed below both the patient and the Vivo 3.
This is to prevent personal injury from accidental spillage or from excess water or con-
densation flowing down to the ventilator or down the patient tube and into the patient's
mask. Extra cautions should be taken for patients who are unable to guard their airways
or cannot pull off the mask.
Risk of Inflammation
Incorrect connection of the ventilator may cause inflammation.
The attachable humidifier is only enabled when the Vivo 3 is connected to the AC Power
supply.
16 Safety Information
User Manual
A blocked, clogged or in other ways occluded leakage port causes exhaled gases to
be rebreathed.
With low pressures the risk of rebreathing increases.
I:E (inspiration time : expiration time) ratios close to 1:1 increase the risk of
rebreathing as the expiratory time allowing exhaled gases to be cleared from the
circuit before the next breath is decreased.
