FOI – 2023-000167 - Oximeters (HTML)

Published on 12 June 2023

Date received – 12 May 2023 | Date responded – 12 June 2023


I need to know what equipment is used to reliably measure SPO2 levels constantly - 24/7 - including when a patient is active.

The NHS must use equipment to record say a week's detailed record of Oxygen levels. The clip on Oximeters are not a reliable way to test a person when they are moving around. The reliable equipment would usually have a rubber type covering which slips onto the finger. Would you please provide me with the following information:

  1. Name of equipment
  2. Brand of equipment
  3. Model of equipment
  4. Whether the equipment is FDA or CE approved

Some people need to be monitored during their normal activities in their normal environment. This is extremely important for instance for a patient who suffers from severe PTSD whilst in the presence of NHS personnel. In fact it is the only way to obtain a reliable record of a patient in these circumstances.


Please find attached FOI – 2023-000167 Appendix 1 - Monitors with Sp02 capability. This appendix will provide you with all of the current monitors that are on the framework, NP173/19 - Patient Monitors, Anaesthetic Machines and Ventilators.
