An oscillometric waveform (OMW) envelope-based blood pressure (BP) monitoring device is widely used to monitor blood pressure and prevent hypertension and adverse cardiovascular events. At present, all primary care physicians and clinicians widely recommend oscillometric-based BP devices. The consumer selects the device based on their own decision, without knowing whether the device is validated or not, resulting in over- or under-treatment of hypertension. It is imperative that each device must comply with international protocols. In this study, we have investigated the accuracy of inflation and deflation-based oscillometric BP monitoring devices in the case of sinus rhythm (SR). Since different health conditions of the patient affect the oscillometric waveform, which can affect the device’s accuracy, in such cases, many BP monitors are skeptical of succeeding in the norms of international protocols. Therefore, this study also aims to calculate the accuracy of these devices in various health conditions and measure the effect of pulse volume, arrhythmia, and respiratory artifact on it using a non-invasive blood pressure (NIBP) simulator. We found that the oscillometric BP devices failed to measure the correct blood pressure in several clinical conditions.

基于示波波形（OMW）包络的血压（BP）监测装置广泛用于监测血压并预防高血压和不良心血管事件。目前，所有初级保健医生和临床医生都广泛推荐基于示波法的血压设备。消费者根据自己的决定选择设备，而不知道设备是否经过验证，导致高血压治疗过度或治疗不足。每个设备都必须遵守国际协议。在本研究中，我们研究了基于充气和放气的示波血压监测设备在窦性心律 (SR) 情况下的准确性。由于患者的不同健康状况会影响示波波形，进而影响设备的准确性，因此在这种情况下，许多血压监测仪对能否成功遵守国际协议规范持怀疑态度。因此，本研究还旨在计算这些设备在各种健康状况下的准确性，并使用无创血压（NIBP）模拟器测量脉搏量、心律失常和呼吸伪影对其的影响。我们发现示波血压计在多种临床情况下无法测量正确的血压。
