To determine whether the muscular activity required to inflate a blood pressure cuff for self-recording influences the blood pressure at the instant of the subsequent measurement, finger blood pressure was recorded continuously during cuff inflation. Ten normotensive and seven untreated hypertensive subjects used their dominant hands to inflate, in 5 s, an occluding cuff on the same arm up to 200 mmHg. Blood pressure in the middle finger of the other arm was measured continuously by the Finapres device. Korotkoff sounds were determined by a microphone in the arm cuff, and the speed of deflation was kept constant by the investigator at 2-3 mmHg/s. Systolic pressure rose at the onset of inflation, with an average peak of 13 +/- 6 (s.d.) and 12 +/- 8 mmHg above baseline in the normotensive and hypertensive subjects, respectively. Five seconds after the onset of deflation both systolic and diastolic pressures in both groups had returned to baseline levels. Thus, self-inflation of a blood pressure cuff allows a valid measurement of blood pressure provided the recommended guidelines are strictly followed.
为了确定自行记录血压时给血压袖带充气所需的肌肉活动是否会影响随后测量瞬间的血压，在袖带充气过程中持续记录手指血压。10名血压正常者和7名未经治疗的高血压患者用优势手在5秒内将同一手臂上的阻断袖带充气至200 mmHg。用Finapres装置连续测量另一手臂中指的血压。通过袖带中的麦克风确定柯氏音，研究者将放气速度保持恒定在2 - 3 mmHg/秒。充气开始时收缩压升高，血压正常者和高血压患者分别比基线平均峰值高13±6（标准差）和12±8 mmHg。放气开始5秒后，两组的收缩压和舒张压均恢复到基线水平。因此，只要严格遵循推荐的指导原则，自行给血压袖带充气就能有效地测量血压。
