Performed in a clinical setting, m-HBOT has repeatedly been shown to be extremely safe. The only noted side effects have been limited to higher-pressure chambers used to treat acute life-threatening conditions in hospitals, and even those side effects are very rare.
It should be noted that the only absolute contraindication for undergoing HBOT is a collapsed lung (pneumothorax).
Areas of concern would be:
Severe lung or heart disease: This is because we would not want fluid to build up into the lungs.
Uncontrolled Diabetes: This is because we do not want the blood sugars to drop too low if HBOT was combined with overdose of diabetic drug therapy.
History of Seizure or Uncontrolled fever: This is because we would be concerned with exacerbating seizure activity, particularly if blood sugars are low.
Changes in Vision: This is rare and a temporary change in vision that has been associated with higher pressure chambers and not m-HBOT. Changes in vision include getting either a little worse (Myopia) or better (Presbyopia). Note: these cases are rare and associated with higher oxygen dosages. If you notice any changes, please let the attendant know and don’t worry as the vision tends to go back to its original state within 3 months from discontinuing the sessions. For that reason, it is not advised to change prescriptions during this time period.
History of Cataracts: Though HBOT cannot cause cataracts, this procedure may cause formed cataracts to mature more quickly.
Pregnancy: As a precautionary measure, HBOT is not used during pregnancy unless indicated for acute life-threatening conditions.
Current upper respiratory infections, chronic sinusi tis or sinus problems: These conditions cause a higher probability of problems during pressurization and are generally recommended to be treated before going into HBOT.
Claustrophobia: Some clients may suffer from Claustrophobia. This is managed by maintaining communication, use of relaxation techniques and mild sedation, if necessary. If you have a problem with this condition please let us know.
