ABSTRACT:
An arterial manometric dressing includes a pressure applying assembly having a pressure pad at a lower end thereof. A Doppler probe for determining blood flow in an artery forms part of the pressure applying assembly and engages an upper wall of the pressure pad, through which ultrasound signals are adapted to be transmitted. The pad also has a lower surface spaced from the upper surface for engaging a patient in a region for apply a pressure to an artery, and a fluid for transmitting ultrasound signals to and from the Doppler probe is disposed between the upper and lower walls of the pad. The dressing also employs a pressure indicating device for indicating the amount of pressure being applied to the artery. The invention also resides in the fluid-filled pressure pad, both alone and in combination with the Doppler probe.
