Decompression sickness: risk factors and the monoplace chamber--a case report.

Discussions regarding the use of monoplace chambers for the treatment of decompression sickness (DCS) have continued for some time. Recently the role of these chambers has been reviewed by Kindwall (12) and critiqued by Moon (13). Various principles and concerns presented in their articles are illustrated by this case presentation of type II (serious) DCS with pulmonary and neurologic manifestations. Closely timed recurrent altitude exposure is discussed as a risk factor for DCS. Also, a newly defined risk factor (menstrual phase) is considered relevant to this case. Finally, we recommend that arrangements be made early in the management of DCS cases for transfer to a chamber which can provide definitive therapy.
