Set- Up

 

 

Before you use the Bedfont NOxBOX

i

 intelligent Nitric Oxide delivery and monitoring system it is important to follow these steps:

Ensure the device does not require maintenance (monthly) and that the maintenance is not due during the expected duration of the therapy such as:

•  NO sensor high calibration

•  NO

sensor high calibration

•  Pump calibration

•  Vent calibration

Checklist

•  Ensure the device is clean and free from damage

•  Ensure the water trap is empty and has been cleaned from previous use

•  Ensure all single use items from previous patient have been discarded

Equipment  you will need for set-up:

•  A NOxBOxi system test kit (NOXBOX-I TEST)

•  A NOXKIT (inspiratory limb size dependant)

•  Two cylinders of delivery gas

•  A 22mm one-way valve for HFO ventilator circuits (FXS555)

Additional items

•  NOxAIR Environmental monitors

•  Manual bagging kit

NOTE: If you do not have the parts listed above or the device has not been maintained the NOxBOX

i

 may not be suitable for use and you may be unable to 

set-up the device. Failure to follow these procedures may result in harm to to the operator or the patient.
