HBO Dose Titration
The clinical application of Hyperbaric Oxygen Therapy (HBOT), although based on sound physiological principles as well as on a logical rationale, has often been characterized by empirical procedures, and the choice of the treatment schedules has been more fortuitous than rational. The indication for HBOT and the treatment protocol are originated by the general and often acritical assumption that a given lesion or malfunction is caused, facilitated or worsened by hypoxia. Furthermore, the increasingly common use of multiplace hyperbaric chambers, where many patients can be treated at the same time, although maximizing the cost benefit ration of HBOT and the performance of the chamber technical and nursing personnel justified the commonly adopted routine of using average treatment pressures and schedules without considering the differences between indications, patients, disease conditions and the evolving physiopathological stages of the healing process in the individual patients. As a consequence, it is quite frequent to witness the very strange paradox that a treatment based on extremely solid physiological grounds is often applied empirically and nonrationally.
