Hyperbaric oxygen therapy (HBO2 ) is recommended in different conditions associated with the necessity to increase the oxygenlevel in affected tissue. The principle of treatment is to increase the oxygen supply to ischaemic tissue by supplying oxygendissolved in blood during increased surrounding pressure. Transcutaneous measurement of partial oxygen pressure (PtcO2 ) is usedfor indications of ischaemic affections for hyperbaric oxygen therapy.HBO2 was applied at a pressure of 0.28 MPA for a period of 80 mins. Values of PtcO2 under these conditions were notpublished so far. The authors investigated PtcO2 values in 29 patients with ischaemic disorders of the lower extremities, placing theelectrode on the tarsus of the foot and on the external side of the crus. The control group comprised 127 patients, treated withHBO2 on account of other diseases. For statistical comparison the double-selection t-test with unequal scatter was used.The PtcO2 values on the healthy tarsus increased during HBO2 roughly eight times (from ca 60 to 480 mmHg). On the affectedextremity roughly five times (from ca 60 to 300 mmHg). The differences of the two groups were statistically significant (p
