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...
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...
متن کاملArterial oxygen tension in relation to age in hospital subjects.
One hundred and seventy-seven hospital patients whose ages ranged from 20 to 80 years were studied to determine whether or not there are any changes in arterial oxygen tension (during the breathing of room air) in relation to age. The findings indicated that there is an inverse correlation between age and arterial oxygen tension. This may be of great clinical significance since anoxemia has a p...
متن کاملTranscutaneous oxygen tension in subjects with tetraplegia with and without pressure ulcers: a preliminary report.
This study compared transcutaneous oxygen tension (TcpO2) in subjects with paraplegia and pressure ulcers (PU), those with paraplegia and no pressure ulcer (NPU), and ambulatory controls. TcpO2 was measured using a surface-electrode monitoring system, recorded at 1-min intervals for 5 min and averaged. Mean TcpO2 was significantly lower in the PU than the NPU and control groups (23.53+/-1.83 vs...
متن کاملTranscutaneous estimation of arterial carbon dioxide in intensive care. Which electrode temperature?
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...
