The photoplethysmographic wave is displayed by most pulse oximeters. It may be used as a non-invasive alternative to invasive arterial blood pressure trace analysis for continuous haemodynamic monitoring in selected situations.
Four cardiac patients treated in a tertiary neonatal-paediatric intensive care unit.
Simultaneous monitoring of the photoplethysmographic wave, ECG, and invasive blood pressure.
Photoplethysmography allows for monitoring pulse rate in patients with (possible) heart rate/pulse rate dissociation (pacemaker dependency, pulsatile ventricular assist device); monitoring sudden changes in heart beat volume, which are unrelated to respiration (pulseless electrical activity, pulsus alternans); and monitoring respiratory-dependent fluctuations of the plethysmographic wave (heart failure, hypovolaemia, asthma, upper airway obstruction, pericardial effusion). Deterioration, slowly evolving over time, may be detected by this method.
大多数脉搏血氧仪可显示光电容积脉搏波。在特定情况下，它可作为有创动脉血压波形分析的无创替代方法，用于连续血流动力学监测。
四名在三级新生儿 - 儿科重症监护病房接受治疗的心脏病患者。
同时监测光电容积脉搏波、心电图和有创血压。
光电容积脉搏波描记法可用于监测（可能）存在心率/脉搏率解离（起搏器依赖、搏动性心室辅助装置）的患者的脉搏率；监测与呼吸无关的心跳量突然变化（无脉电活动、交替脉）；以及监测光电容积脉搏波的呼吸依赖性波动（心力衰竭、低血容量、哮喘、上气道梗阻、心包积液）。通过这种方法可以检测到随时间缓慢发展的病情恶化。
