AVEA ventilator systems
J. Expiratory Hold
When the EXP HOLD button is pressed, at the start of the next breath interval the ventilator will not allow the patient to
inspire or exhale for a maximum of 20 seconds (adult/pediatric) for breath rates 20 and less, 25 seconds for breath rates
greater than 20, or 3 seconds (neonate). Expiratory Hold is NOT active in TCPL breaths.
K.

Inspiratory Hold (Manual)

When the INSP HOLD button is pressed, once the preset of a volume control or pressure control breath has been
delivered, the patient will not be allowed to exhale for a maximum of 3.0 seconds (± 0.1 second).
L. Nebulizer
The ventilator supplies blended gas to the nebulizer port at 10 ± 1.5 psig (0.7 bar) when an in-line nebulizer is attached
and the Nebulizer key is pressed, provided that the calculated delivered flow is >15 L/min.
Delivery of the nebulized gas is synchronized with the inspiratory phase of a breath and lasts for 20 minutes. Press the
Nebulizer key a second time to end the treatment prior to the end of the 20-minute period.
CAUTION
Use of an external flow source to power the nebulizer is not recommended.
WARNING
Using the nebulizer may impact delivered tidal volumes.
Note:
Do not operate the nebulizer while using heliox

Patient Size

Note:
The ventilator will not allow patient size changes when the active mode of ventilation is not available in the new patient
size selection. The ventilator will display a message instructing you to first change the ventilation mode. For example,
in neonatal ventilation with TCPL active, you cannot change to a pediatric or adult patient size without first changing
the mode to one available for those patients.
The ventilator will also not allow size changes if Machine Volume is active. A message displays indicating that
Machine Volume must first be turned off before making a patient size change.

The Patient Size Indicators for Adult, Pediatric, and Neonate at the bottom of the UIM show which
patient size is currently selected. These LED indicators have no associated membrane button on the
UIM.
