Hello RC My brother in law is in a long term care facility/hospital and has been diagnosed with Anoxic Encephalitis Brain Damage, he has renal failure (receives dialysis three times a week), three toes recently amputated (for which he had HBO for in the past)and peripheral neuropathy .... I have read the "HBO" is a recommended treatment modality ... but have had great difficulty locating a HBO facility/hospital who will take vent dependent patients .... does anyone know where there is a "HBO" facility/hospital that will accept vent dependent patients. If not how do you "wean" a semi-comatose patient off of a vent and can a speaking valve be used with this type of patient.
