Effects of the transcutaneous electrode temperature on the accuracy of transcutaneous carbon dioxide tension
AIM The harmful effect of hypocapnia on the neonatal brain emphasizes the importance of monitoring arterial carbon dioxide tension (PaCO2). Transcutaneous monitoring of carbon dioxide (tcPCO2) reduces the need for arterial blood sampling. Drawbacks are high electrode temperature causing risks of skin burning. The aim was to determine the accuracy and precision of tcPCO2 at reduced electrode tem...
متن کاملMulti-Electrode Array for Transcutaneous Lumbar Posterior Root Stimulation.
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...
متن کاملThe Effects of Subcutaneous Fat, Electrode Size and Inter-Electrode Distance During Transcutaneous Electrical Stimulation
Transcutaneous electrical stimulation is used as an adjunct therapy for obesity, where it can enable increased levels of voluntary exercise. Due to the high resistivity of subcutaneous fat tissue, however, high stimulus currents are required to evoke muscle contraction in obese subjects, possibly leading to patient discomfort. In this study, a three-dimensional finite element model of the human...
متن کاملSafety System Design Simulation for Transcutaneous Electrical Nerve Stimulator using Electrode Contact Test
TENS (Transcutaneous Electrical Nerve Stimulator) is a therapeutic device used to deliver electric current through one’s skin. As the device is used on the human body, safety concern becomes a matter that needs special attention. One option for electrical safety is testing whether the electrode has attached properly to the skin. The test is done in the interval of the simulator pulse. This opti...
متن کاملUnderestimation of arterial oxygen tension by transcutaneous electrode with increasing age in infants.
To investigate the effect of increasing gestational and postnatal age on the relation between transcutaneous oxygen tension (tcPO2) and arterial oxygen tension (PaO2) 160 simultaneous measurements of tcPO2 and PaO2 tensions were made on 42 infants born at 24-41 weeks' gestation and aged 0-32 weeks from birth. Irrespective of gestational age a progressive fall in the tcPO2:PaO2 ratio with increa...
