Attaching Flow Sensors

The AVEA can accept either a hot wire or a variable orifice proximal flow sensor. These are in addition to the
instrument's internal inspiratory flow sensor and heated expiratory flow sensor. Three proximal flow sensors are available
for the AVEA.
The standard Hot Wire flow sensor is suitable for neonatal and pediatric applications where the peak inspiratory flow rate
is less than 30 L/min. This flow sensor is not active in adult applications.

Hot Wire Flow Sensor

A Hot Wire flow sensor attaches to the receptacle
circled in light blue directly below the variable orifice
flow sensor connection on the front panel. The
receptacle is marked with the icon shown here.
This is a locking connector. To attach, first pull back
the locking collar, then push firmly onto the ventilator
receptacle.
To disconnect, first retract the plastic collar then
firmly pull the connector away from the ventilator.
Do not pull up or down as this can damage the
connector
CAUTION
Flow sensors must be attached at both the patient wye and at the ventilator connection to ensure proper function of
the AVEA.
Note:
Hot wire flow sensors will not function with Heliox gas mixtures. During Heliox delivery, a variable orifice flow sensor
should be used for monitoring delivered volumes at the proximal airway.
