The capacity utilization of the chambers depends on the number of treatment sessions<br />

per day and the average occupancy rate of the chamber during the sessions.<br />

Number of treatment sessions per day<br />

A treatment session takes about 150 minutes, i.e. a dive of 90 minutes and<br />

approximately half an hour work before and after the treatment. As a result, a<br />

hyperbaric chamber could effectively be used for up to four treatment sessions per day.<br />

However, at the Belgian centres, the chambers are used either ad hoc for emergency<br />

cases (mainly for the monoplace chambers), or at a fixed scheme of one or two sessions<br />

per day (for multiplace chambers).<br />

Number of patient treatment sessions per year<br />

Based on the data we received, the monoplace chambers are used from about 15 to<br />

270 sessions per year. The multiplace chambers are used from 870 “treatment sessions”<br />

per year (meaning 870 times that a patient receives a 90 min session) up to 2 700 at<br />

two hospitals and about 3 200 at the Military Hospital.<br />

Occupancy rate of the chambers during a session<br />

Based on the two above mentioned inputs and combined with the size of the chamber,<br />

the average occupancy rate of the chambers was calculated. Not taking into account<br />

whether a patient is sitting or lying, the estimated occupancy rate for the multiplace<br />

chambers varies from 30% to over 90%.<br />

5.7.2 Results from financial and clinical registration data<br />

The primary objective of this combined Minimal Clinical Data (MCD) and Minimal<br />

Financial Data (MFD) analysis is to complement the data provided through<br />

questionnaire by the HBOT centres concerning utilisation of HBOT. It is important to<br />

note that ambulatory patients are not included in this analysis.
