Which types of devices/techniques should be used to monitor the oxygenation status of patients undergoing hyperbaric oxygen therapy?

1. Transcutaneous monitoring
2. Arterial blood gas monitoring
3. End-tidal CO2 monitoring
4. Spirometer
a. 1 and 2 c. 2 and 3
b. 1 and 4 d. 3 and 4

ANS: A
Transcutaneous monitoring has proven to be valuable in the assessment of the overall oxygena-tion status of a patient undergoing hyperbaric therapy. Arterial blood gas monitoring can provide information on the oxygenation status of patients receiving hyperbaric therapy and can also give an indication of their ventilatory status.
