Steps Action

1

 Remove analyser from respiratory circuit for calibration. Occlude port in circuit to ensure continued flow to infant.

2

If the infant is receiving <60% oxygen then calibrate to 9room) air.

 

If the infant is receiving >60% oxygen the analyser needs to be calibrated to 100%oxygen.

  • plug the analyser sensor to the calibration jig (from the equipment room)

  • plug in a flow regulator to the oxygen port on the ponta and attach the calibration jig 

  • attach oxygen calibration jig to sensor
