A prospective randomised controlled study was performed in order to study the effectiveness of a device designed to reduce the variability in intra-abdominal pressures generated by individuals performing the Valsalva manoeuvre. One hundred women were recruited to take part in the project which compared a traditional Valsalva manoeuvre following standardised verbal instruction with forced expiration through a flow restriction device called a "valsalvometer". The abdominal pressure was measured using an air-filled rectal balloon catheter linked to a pressure transducer. The use of the valsalvometer was associated with a reduction in variation of intra-abdominal pressure between women to 50% of the standard deviation. The new device has the capacity to reduce the variation in intra-abdominal pressure produced when performing the Valsalva manoeuvre. The rise in intra-abdominal pressure may act as a standard against which other measurements are made.
为了研究一种旨在减少进行瓦尔萨尔瓦动作的个体所产生的腹内压变异性的装置的有效性，开展了一项前瞻性随机对照研究。招募了100名女性参与该项目，该项目将遵循标准化口头指令的传统瓦尔萨尔瓦动作与通过一种名为“腹压计”的流量限制装置进行的强制呼气进行了比较。使用连接到压力传感器的充气直肠球囊导管测量腹压。使用腹压计可使女性之间腹内压的变化减少至标准差的50%。这种新装置有能力减少进行瓦尔萨尔瓦动作时产生的腹内压变化。腹内压的升高可作为进行其他测量的标准。
