[Reliability of the transcutaneous PO2 measurement in the adult by the TCM 1 radiometer electrode].

The accuracy of transcutaneous PO2 measurements (PtcO2; Radiometer TCM 1) was evaluated by comparison with arterial PO2 (PaO2) on 115 recordings in 35 patients: 20 during exercise testing (group I) and 14 during assisted ventilation at different FIO2 values (group II). The correlation coefficient between PaO2 and PtcO2 was satisfactory (r = 0.977; n = 115). However PaO2 and PtcO2 mean values were significantly different in group I, and in group II at 45% FIO2. The analysis of variance showed that the difference between PaO2 and PtcO2 was significant among the patients but did not vary with exercise and FIO2 changes (group I: F19 = 6.28, p less than 0.001; group II: F19(19) = 2.54, p less than 0.025). In the adult, transcutaneous PO2 measurement by TCM 1 radiometer electrode seems to be interesting in the context of monitoring blood gases with exercise and assisted ventilation. The significant variation with arterial PO2 sometimes registered should make one cautious in the interpretation of accurate measurements.

[Asbestos exposure and pleural calcification : functional effects in 34 patients].

Respiratory function disturbances were evaluated in 34 patients, mostly retired naval shipyard workers, with asbestos-related pleural calcifications. All patients had spirography tests, while 20 of them were studied by CO transfer in steady-state and measurements of arterial gases. Results were correlated with previous clinical history (chronic bronchopathy and/or pleural effusions), smoking habits, and the duration of exposure to asbestos dust. Patients with no previous history had mean spirographic values close to the normal (VC: 96% of lower limits; TC: 113%, mean VEMS/CV: 72.5%). Previous clinical history had a very much more marked effect on spirographic results than on gas exchanges: whereas CO transfer and blood gases were usually fairly normal (97% of normal for TCO and DuCO, mean PaO2 at 78 mmHg, mean PaCO2 at 34,5 mmHg), many patients had markedly altered altered values. A clear correlation was found for TCO, DuCO, Du a and PaCO2 with the duration of exposure. This suggests that in some cases there is a certain degree of pulmonary fibrosis associated with the pleural thickening.
