Warning: Make sure Evone is not used in an oxygen enriched environment.
Risk on fire or explosion.
1.6 Benefits and Complications
1.6.1 Potential Benefits
The following benefits as compared to volume controlled ventilation (VCV) and pressure
controlled ventilation (PCV) may be expected while ventilating patients in FCV
®
mode:
• Improved lung recruitment and less atelectasis
1–4
• Better aeration of the lungs
1–5
• Higher ventilation efficiency (oxygenation and CO
2
removal)
2–4,6
• Lower energy dissipation in the lungs
3,7,8
1.6.2 Potential Complications
(Long term) use of tubes can result in mucosal damage due to cuff and tube contact.
• Long term use of Evone may result in mucosal damage due to dry air.
Always use an HME filter.
• Prolonged mechanical ventilation carries the risk of metabolic disturbances.
• Large negative intratracheal end expiratory pressures may result in harm to the patient.
Prevent when possible. Negative End Expiratory Pressure (NEEP) may only be applied in
situations of hemorrhagic shock (for more details see 6.5.3).
1.7 Generic warnings
Warnings
Before using Evone, make sure an alternative ventilation method is available for the specific
patient. When using Tritube, the advised alternative is the use of Ventrain. Other
alternatives may include balloon ventilation through a (laryngeal) mask or a conventional
tube, preferably inserted parallel to Tritube. When using conventional tubes in combination
with the Evone conventional tube adapter, switch to the preferred conventional ventilation
method (e.g. balloon).
Read all the Instructions for Use (if available) of used accessories before first use of the device.
Only use accessories specified within this Instructions for Use. Use of accessories,
transducers and cables other than those specified in this manual could result in decreased
performance, increased electromagnetic emissions or decreased electromagnetic immunity
of this equipment and result in improper operation.
Portable RF communications equipment (including peripherals such as antenna cables and
external antennas) should be used no closer than 30 cm (12 inches) to any part of Evone,
including cables specified in this manual. Otherwise, it could result in degradation of the
performance of this equipment.
