Assessment of Cardiovascular Regulation to Lower Body Negative Pressure in Bedridden Disabled Patients
Disabled patients who are bedridden over a long period of time may be considered to be exposed to a continued weightlessness, similar to subjects in space flight. Cyanosis, edema, and cerebral anemia appear frequently in these patients simply because of passive orthostatic posture. These symptoms imply a deterioration in cardiovascular function which has occurred during the years of enforced bed rest in these patients. The purpose of the present study was to identify the cardiovascular response to lower body negative pressure (LBNP) in severely disabled patients during prolonged recumbency.
