Valsalva氏法提出已有300余年。20年前曾用于肺病病人的心功能试验。收缩期动脉血压对此法的反应可分为4期:Ⅰ期(开始用力期),动脉血压暂时升高,Ⅱ期(持续用力期),血压明显下降至基础水平以下,Ⅲ期(开始松弛期),血压复又上升,Ⅳ期(完全松弛期),收缩期血压明显升高。本文附1组有呼吸困难的COPD病人行床旁Valsalva氏法,操作时监测血压,以检出休息时心功能不全。
Valsalva’s law has been proposed for more than 300 years. Twenty years ago was used in patients with lung disease heart function test. Systolic arterial blood pressure response to this method can be divided into four phases: stage Ⅰ (onset of forced period), arterial blood pressure temporarily elevated, Ⅱ (sustained force period), blood pressure decreased significantly below the basal level, Ⅲ (onset of relaxation Period), blood pressure increased again, Ⅳ (complete relaxation), systolic blood pressure was significantly increased. This article attached to a group of dyspneic patients with COPD bedside Valsalva’s method, the operation of monitoring blood pressure, to detect resting heart failure.
