the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...

BACKGROUND Accurate and reliable measurement of gas exchange during exercise has traditionally involved arterial cannulation. Non-invasive devices to estimate arterial oxygen (O2) and carbon dioxide (CO2) tensions are now available. A method has been devised and evaluated for measuring gas exchange during exercise with a combined transcutaneous O2 and CO2 electrode. METHODS Symptom limited ex...

This study models the use of transcutaneous electrical nerve stimulation on skin with a disk electrode in order to simulate tissue damage. The current density distribution above a disk electrode is known to be a dynamic and non-uniform quantity that is intensified at the edges of the disk. The non-uniformity is subject to change through using various electrode geometries or stimulation methods....

The response of the bronchi to nebulised salbutamol was measured in five recurrently wheezy infants. Changes in oxygenation (measured by pulse oximeter and transcutaneous P02 electrodes) and carbon dioxide (measured by transcutaneous PCO2 electrode) were recorded at the same time. Neither nebulised saline nor salbutamol caused any changes in the measurements of airway function. A significant dr...

Transcutaneous and arterial carbon dioxide were measured simultaneously in 57 children (age range 10 days to 14.3 years) undergoing intensive care. All were haemodynamically stable at the time of study. Mean calibration time with 5 and 10% carbon dioxide was 43 (range 38-58) minutes and mean arterialisation time was 10.5 (range 3-30) minutes. Duplicate hourly arterial samples over a four hour p...

This document provides guidelines for the terminology, methodology, and for the interpretation of data obtained from the use of skin (transcutaneous) po(2) and pco(2) electrodes. The transcutaneous technique has found special application in newborn infants. The causes of analytical bias with respect to arterial blood gas values, and imprecision obtained with transcutaneous pco(2) electrodes, ar...

After the first report by HUCH, HUCH, MEINZER and LÜBBERS on transcutaneous measurements of oxygen tension several papers describing this or similar electrodes based on the CLARK principle have been published [l, 3, 4, 12, 15, 18]. The technique has mainly been tested in perinatal medicine, but also in adults [7,8,13]. A publication on intrapartum registrations of human fetuses in considerable ...

Interest in transcutaneous electrical stimulation of the lumbosacral spinal cord is increasing in human electrophysiological and clinical studies. The stimulation effects on lower limb muscles depend on the depolarization of segmentally organized posterior root afferents and, thus, the rostro-caudal stimulation site. In previous studies, selective stimulation was achieved by varying the positio...
