A portable hyperbaric chamber may be designed for emergency therapy that can be administered to the patient immediately after the accident or incident, hence boosting the patient's chances of survival. Because the objective is to create an emergency device, the large oxygen cylinder used to give full oxygen to the patient within the chamber is omitted, hence preserving the hyperbaric environment inside. The scope of this project is defined by determining the patient health factors that influence the patient prior to having therapy and by providing a safe route for HBOT through a system that monitors the parameters to ensure that the treatment is appropriate for the patient's condition. The patient's ECG, heart rate, breathing rate, and temperature are recorded, and the patient's history is saved on a patient card that is read by a card reader. © 2022 Elsevier B.V., All rights reserved.
