An accurate and non-invasive method of assessing the arterial oxygen tension and viability of skin would be invaluable in many clinical conditions including respiratory disease, shock, peripheral vascular disease and limb trauma.
A transcutaneous oxygen monitor has been developed as a non-invasive method ´ to determine local tissue perfusion.
Transcutaneous oxygen tension was measured in 216 Korean without cardiopulmonary and peripheral vascular disease. With a modified Clark-type oxygen electrode, transcutaneous oxygen tension was monitored at the precordial region, distal thigh, anterior and posterior proximal calf, dorsum of foot, and dorsum of hand.
Following conclusions have been obtained:
1. -Mean transcutaneous oxygen tension of the precordial region, distal thigh, anterior and posterior
proximal calf, dorsum of foot, and dorsum of hand was 61.79. 6 mmHg, 57.8_10.0 mmrig, 74-
9.6 mmHg, 57.011.8 mmHg, 57.79.2 mmHg, and 56.8+9. 8 mmHg in the order named.
2. Mean transcutaneous oxygen tension of the precordium was higher than that of dorsum of foot(p<
0.01), but there was no significant pressure gradient ´between the proximal and distal part.
3. Transucutaneous oxygen tension(tcPO,) of the first decade was slightly higher than that of the seventh
decade(p<0. 01), but there was no significant linear age regression between the adjacent age ;roues.
4. There was no significant difference in tcP02 between male and female.
5. There was no significant difference in tcP02 between anterior proximal calf and posterior proximal call´.
6. Mean tcPO2 of dorsum of foot in supine increased significantly(p10.01) when subjects sat up._
7. The transcutaneous oxygen tension was not lower than 30 mHg at any sites of normal; subjects, ranging from 31 mmHg to 81 mmHg.
