Transcutaneous PO2 measurement

Transcutaneous pO2 measurement during tourniquet-induced venous occlusion using dynamic phosphorescence imaging.

A sufficient oxygen supply in skin grafts requires a functioning microcirculation. Venous occlusion impairs the microcirculation and is therefore a major threat of healing. Luminescence life time imaging (LLI) enables the non-invasive and two-dimensional assessment of the transcutaneous oxygen partial pressure (p(tc)O2). In the current trial this new device was applied for monitoring of venous ...

Transcutaneous and capillary pCO2 and pO2 measurements in healthy adults.

Transcutaneous carbon dioxide and oxygen tensions (tc-pCO2 and tc-pO2) were measured in seven healthy adult volunteers during hyperventilation in atmospheric air and during CO2 inhalation. Three skin sensors were applied to each subject: an O2 electrode, a CO2 electrode, and a combined O2-CO2 electrode, each heated to 44 degrees C. We observed close correlation between tc-pCO2 and capillary-pCO...

Reliability of transcutaneous monitoring of arterial PO2 in newborn infants.

Performance of transcutaneous PO2 and PCO2 dual electrodes in adults.

Three commercially-available combined PO2-PCO2 electrodes were assessed in vitro, and in adults breathing air, hypoxic and hypercapnic mixtures, for speed of response, correlation with end-tidal gas tensions and drift. Differences in the 90% response time of the individual electrodes were more marked in vitro than in vivo. Changes in end-tidal gas tensions were reflected by proportionate change...

transcutaneous bilirubin measurement in preterm neonates

hyperbilirubinemia is a common problem during neonatal period especially in preterm neonates. transcutaneous bilirubin measurement (tcb) by special devices had been documented as an effective tool for predicting neonatal jaundice in full term neonate, but for preterm infants the present evidences are controversial. we carried out a prospective study in shariati hospital nicu. 126 paired tcb/tot...
