Table 2 Definitions of TcpO2 quantities

Baseline

The arithmetic mean of maximum TcpO2 at rest.

TcpO2_max

The highest TcpO2 value recorded every minute of exercise or at rest.

Maximum change from baseline (ΔTcpO2_max)

The outcome of the subtraction of baseline from TcpO2_max: e.g. TcpO2_max - baseline

Changes in transcutaneous oxygen pressure (ΔTcpO2)

The average sum of the change from baseline at rest and exercise period: e.g. (Σ)ΔY1…n) / n) = ΔTcpO2
