    To Operate the Faught Pocket and the Faught Clinical Sphygmomanometers. Apply the arm-band to the bared arm of the patient, above the elbow, by placing the broad end, containing the rubber bag, over the region of the brachial artery. Wrap the rest of the band as you would a bandage about the arm (see Fig. 12) and tuck the narrow end in under the first turn. Attach the indicator to the hook provided for that purpose; attach the pump to one nipple, and the tube from the arm-band to the Fig. 12.—Pocket Indicator Applied to Arm. other. See that the needle valve on the pump is fully closed. Hold the pump in one hand and locate the pulse at the wrist with the other. You are now ready to take the systolic pressure. To obtain systolic reading.—Pump sufficient air in the system to obliterate the pulse, then by a fraction of a turn open the valve (see Fig. 12), gradually release the air pressure, and note the pressure indi- cated when the first pulse beat returns to the wrist. This is systolic pressure. Repeat the procedure one or more times to insure correct readings. Work rapidly, as prolonged pressure upon the arm will affect the reading.
