With the entrainment of oxygen in a ventilator, an FiO2 sensor is necessary to monitor the patient’s inspired oxygen concentration (FiO2).
The FiO2 sensor has three components. Installation involves the following steps:
- Connect the FiO2 sensor to the middle of the T-piece adapter
- Connect the sensor cable to the top of the FiO2 sensor
- Connect one end of the T-piece to the patient circuit outlet on the right side of the VIVO 55 ventilator
- Connect the white FiO2 sensor cable to the white FiO2 outlet, found on the right side of the device
On installation of a new oxygen cell, the machine should be calibrated:
- Assemble the FiO2 sensor, as above
- Connect an oxygen supply to the oxygen inlet on the right side of the device
- Switch on the ventilator
- To access the calibration in the menu, select the ‘others’ menu, and locate the ‘FiO2/ CO2 calibration’ option
- Follow the on-screen instructions to calibrate the FiO2 sensor
Once the FiO2 sensor has been set up and calibrated, the machine will give a FiO2 reading when the ventilator is running. The FiO2 sensor will need changing approximately every 6-months.
It’s important to note, oxygen should only be entrained while the device is running.
