چکیده

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 increasing postnatal age was found. At all postnatal ages tcPO2:PaO2 tended to be lower in the more mature infants.

Estimation of arterial oxygen and carbon dioxide tensions by a single transcutaneous sensor.

A transcutaneous electrochemical sensor designed to estimate arterial oxygen (Pao2) and carbon dioxide (Paco2) tensions simultaneously and continuously was evaluated in newborn infants with respiratory illnesses. After calibration with two dry gas mixtures the sensor gave estimates of Pao2 and Paco2 that were comparable with those obtained by two separate electrodes that are already established...

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 ...

Estimation of arterial oxygen tension in adult subjects using a transcutaneous electrode.

Transcutaneous oxygen tension (tcPO2) measured with a heated electrode was compared with arterial oxygen tension (PaO2) in three groups of adult patients-group A: 20 patients with chronic respiratory disease; group B: eight hypothermic patents studied immediately after cardiopulmonary bypass surgery; and group C: 14 patients in an intensive care unit who had in all 35 comparisons of tcPO2 and P...

Improved accuracy of continuous measurement of arterial oxygen tension in sick newborn infants. Criteria for reading and recalibrating the electrode.

Improved accuracy of continuous arterial oxygen tension (PaO2) measurement is obtained if allowance is made for the response time of the electrode. Recalibration is necessary only when PaO2 measured in a blood sample differs from the electrode value by more than +/- 11.5 mmHg (1.5 kPa).
