Summary PAT Technology is a plethysmographic based measurement method which facilitates the accurate recording of the pulsatile volume changes of the arteries of peripheral vascular beds at the distal end of the fingers over sustained periods of time

Summary Background:Mental stress testing is considered a reliable method for diagnosing patients with coronary heart disease (CHD) who may be at risk for future events. It has been shown recently that myocardial ischemia induced during mental stress

ObjectivesWe sought to assess the added diagnostic value of peripheral artery tonometric (PAT) measurements, based on finger pulsatile arterial volume changes, to standard 12-lead stress electrocardiography (ECG), for detecting exercise-induced myoca

Arousals from sleep are associated with increased sympathetic activation and are therefore associated with peripheral vasoconstriction. We hypothesized that digital vasoconstrictions as measured by peripheral arterial tonometery (PAT), combined with

Pharyngeal obstruction in patients with obstructive sleep apnea (OSA) is thought to result from decreased upper airway muscle tone during sleep. The goal of the present study was to estimate the role of the tongue muscles in maintaining pharyngeal pa

The male predominance in obstructive sleep apnea (OSA) is currently poorly understood although differences in pharyngeal airway anatomy and physiology have been proposed. As the response to inspiratory resistive loading (IRL) provides important infor

A new noninvasive measurement method providing rapid measurement of systemic arterial blood pressure (BP) and its validation is described. The method combines precisely timed electrocardiographic-gated rapid release of occluding counter-pressure (600

The present study evaluated the mechanisms by which upper airway (UAW)-dilating muscle contraction, elicited by hypoglossus nerve (HGN) stimulation, improved UAW patency. Pressure-flow (P-V) relationships of the isolated UAW as well as the negative i

In the present study we examined the effect of flexion and extension of the head on upper airway (UAW) patency in anesthetized dogs, and compared the dilatory and stabilizing effects of electrically stimulated UAW muscles at the different head positi
