  • Page 25: Blood Pressure Measurement

    1. Introduction Thank you for your Purchase! The TM-2441 ambulatory blood pressure recorder enables accurate measurement of patient blood pressure automatically for preset times (e.g. 24-hours continuously). This manual explains the settings, operation, modes and programs for blood pressure measurement, as well as communication with a dedicated peripheral, maintenance, specifications and warnings.
  • Page 26 Purpose of use The recorder is equipped with two modes for blood pressure measurement. Blood pressure values can be used for consulting with doctors and self-health management. Automatic blood pressure measurement (A-BPM) This mode can specify six pairs of arbitrary start times and intervals for every 24 hours and can automatically measure and record blood pressure.
  • Page 27 Extensive analytical performance The measurement interval time can be set for the automatic blood pressure measurement. The blood pressure can be measured immediately using manual measurement at any time. S-BPM is equipped with five programs for varying conditions. The analysis can be carried out effectively using the ABPM Data Manager installed on the computer (dedicated peripheral).

    Appendix 11.1. Principle of Blood Pressure Measurement Measurement procedure: Wrap the cuff around the upper arm. Inflate the cuff to a pressure exceeding the systolic blood pressure. Then, exhaust the air from the cuff gradually. While the pressure is detected in the cuff in the air exhaustion stage, the pulse waveform appears in synchronization with the heartbeat.
