This guide provides step-by-step information on how to replace the Flow Sensor Receptacle for the Cardinal Health Vela Ventilator.
The flow sensor is used for measuring the flow rate of the gas passing through the ventilator. It is a crucial component of the ventilator, and must receive periodic sterilization.
The Flow Sensor may need to be removed/replaced for the following reasons:
- The Flow Sensor must be sterilized in an autoclave.
- The Flow Sensor may need to be replaced if monitored volumes are out of the 20% specification.
Viasys’ replacement guide for the Flow Sensor can be found on page 37 of the service manual attached.
