A system including manometer, cuff, inflator, and stethoscope wherein the manometer has manually-operable "drop-off" pointers. Using the stethoscope, an observer operates the drop-off pointers in succession upon aurally detecting systole and diastole, respectively. The bleed of pressure from the cuff is regulated so that the cuff pressure drops according to a predetermined schedule. Manual operation of the drop-off pointers is caused to reduce the resistance to air flow from said cuff. |
