The recent recognition of the sleep apnea syndrome has forced a re-evaluation of the mechanism of hypercapnia and disordered respiratory control in obese patients. Thirteen obese patients with sleep apnea were studied in an attempt to relate the pattern of sleep abnormality and awake ventilatory control to the presence of chronic hypercapnia. Patients with(More)
The relationship between the resting response to CO2 rebreathing and the ventilatory response to CO2 production during exercise was examined in 20 healthy untrained male subjects and in six patients with obesity hypoventilation syndrome. Patients were chosen because of a severely reduced response to CO2 rebreathing. There was no correlation between the CO2(More)
A portable, easily assembled system that allows quantitative monitoring of ventilation in the sleeping human subject is described. It is a modification of the system used by Kinney et al. (Metab. Clin. Exp. 13: 205-211, 1964) and Spencer et al. (J. Appl. Physiol. 33: 523-528, 1972). The system directly measures gas flow without reliance on indirect CO2 or(More)
Most surgeons believe that incorporation of a pneumatic thigh tourniquet requires concomitant use of general anesthesia to prevent the patient from experiencing intolerable discomfort. These authors explored use of pneumatic thigh tourniquets in combination with local standby sedation by conducting a two-part study. A group of nonsedated student volunteers(More)
The occurrence of fracture of the calcaneus after heel spur surgery can be a devastating complication requiring prompt treatment and strict patient compliance during the postoperative course. The literature contains little information regarding this type of injury. Several factors must be considered in assessing the etiology of the fracture, including(More)
