For these reasons there must be no smoking in or around the hyperbaric chambers. Tobacco constricts blood vessels and limits the amount of blood and oxygen that can be delivered to tissues. Inform the hyperbaric team of all medicines the patient is taking.
Some medications change the body's response to oxygen.
Any signs of illness such as fever, cough, sore throat, nausea, or other symptoms should be communicated to the hyperbaric team. Treatments may need to be delayed until symptoms resolve. Patients should be informed not to drink carbonated beverages for 4 to 6 hours prior to treatment with hyperbaric oxygen. Because of the gas laws affecting gases within the body, these beverages may be hazardous. No synthetic clothing or pantyhose.
