Table 1.5-1. Transcutaneous pressures of oxygen and amplitude of the Doppler laser flow in various pressures of oxygen in 10 cases of localized ischemia

Figure 1.5 -1. Doppler laser flow in ischemic area and normally perfused area in various breathing pressures of oxygen. In the normally perfused area, the Doppler flow decreases whereas PtcO2 increases. In the ischemic area, the Doppler laser flow remains the same whereas PtcO2 does not reach a high level. Note the vasomotion waves in the ischemic areas which are not seen in atmospheric air but appear during HBO.
