HBOT - Contraindications & Precautions

Absolute contraindications:

Include untreated pneumothorax and use of bleomycin, disulfiram, doxorubicin and mafenide acetate. Contraindicated drugs must be discontinued before Hyperbaric Oxygen Therapy.

List of a few known contraindication: 1) History of spontaneous pneumothorax. 2) Severe sinus infection. 3) Upper respiratory infection. 4) Asymptomatic pulmonary lesions on chest x-ray. 5) Uncontrollable high fever (greater than 39C). 6) History of chest or ear surgery 7) Congenital spherocytosis. 8) Any anemia or blood disorder (Although HBOT treats different types of anemia. 9) Any convulsive disorder though many patients have seizure disorder and are treated successfully with HBOT. 10) History of optic neuritis or sudden blindness. 11) Middle ear infection. 12) Diabetes mellitus (insulin therapy). Many diabetic wound patients are diabetic and are treated successfully with HBOT. 13) Pregnancy. 14) Nicotine use/addiction. 15) Acute Hypoglycemia (Many patients are treated successfully with HBOT.) 16) Emphysema with CO2 retention.

Relative contraindications 

Should be observed with caution or consideration, but do not prohibit. They include seizure disorders, emphysema with carbon dioxide retention, high fever, history of spontaneous pneumothorax, optic neuritis, upper respiratory infection, pregnancy, congenital spherocytosis, implanted pace makers and epidural pain pumps. Cancer Chemotherapy agent doxorubicin (Adriamycin) is thought to become cardio toxic when used concurrently with Hyperbaric Oxygen Therapy. Treating patients with Hyperbaric Oxygen Therapy after doxorubicin is stopped for 2-3 days.

Complications & Precautions:

Barotrauma: 

Virtually no patients should have barotraumas if each dive should be observed manually, and at the first sign the pressure is adjusted or reversed to relieve any discomfort.

Confinement Anxiety: 

Oxygen is natural an anti-anxiety agent for patients. A thoruough counseling should remove this condition. Most of the patients get rid of this after the first treatment.

Oxygen Toxicity: 

Pulmonary and CNS – 1 in 10,000 people may experience this but no permanent effects result from this occurrence. There are 14 signs that patients display before experiencing oxygen toxicity that the CHT is trained to recognize. It is recommended that the chambers are operated manually, if a patient should start to display symptoms, the pressure is reversed and symptoms are resolved. Oxygen Toxicity occurs in less than 1 in 10,000 treatments. Does not occur if treated with in recommended pressures and limitation in number of treatments.

Myopia:

Minor eyesight changes due to temporary curvature in the lens while undergoing slight pressurization. Gradually reverses after cessation of HBOT when the lens flattens out again.

Precautions to be followed while entering the Hyperbaric Oxygen Therapy Chamber:

Because the chamber is pressurized with 100% oxygen, certain items can not be taken inside. These include lighters or matches, cigarettes, nylons, wigs, or hair pieces, petroleum jelly, ointments, hearing aids, watches, makeup, lipstick or lip balm, hair spray, hair oil or relaxers, synthetic clothing or hard contact lenses and as advised by your hyperbaric center safety regulations.
