The effects of intermittent pneumatic compression on the healing rates of ulcers in patients with chronic venous insufficiency were examined in a prospective, controlled study of 22 patients. Patients were randomly assigned to the experimental or the control group. Both groups received local wound care followed by application of an Unna boot. In addition, subjects in the experimental group rece...

OBJECTIVE To evaluate the cost-effectiveness of thromboprophylaxis at cesarean delivery with intermittent pneumatic compression. METHODS A decision tree model using Markov analysis was developed to compare two approaches to perioperative care at the time of cesarean delivery: 1) no use of perioperative thromboprophylaxis and 2) the use of intermittent pneumatic compression for thromboprophyla...

OBJECTIVE To evaluate the effect of intermittent pneumatic leg compression on intracranial pressure and cerebral perfusion pressure in brain-injured patients. DESIGN Prospective, sequential patient study. SETTING Surgical/trauma ICU of a community hospital providing regional trauma care. PATIENTS Twenty-four adult, brain-injured patients (mean Glasgow Coma Scale score = 6) who required he...

INTRODUCTION Enhancement of peripheral circulation has been shown to be of benefit in many vascular disorders, and the clinical effectiveness of intermittent pneumatic compression is well established in peripheral vascular disease. This study compares the haemodynamic efficacy of a novel neuromuscular electrical stimulation device with intermittent pneumatic compression in healthy subjects. M...

This paper describes a thermal transpiration-driven multistage Knudsen pump for vacuum pumping applications. This type of pump relies upon the motion of gas molecules from the cold end to the hot end of a channel in which the flow is restricted to the free molecular or transitional regimes. To achieve a high compression ratio, 48 stages are cascaded in series in a single chip. A five-mask, sing...
