Abstract

OBJECTIVE

The goal was to compare Speckle plethysmography (SPG) and Photoplethysmography (PPG) with non-invasive finger Arterial Pressure (fiAP) regarding Pulse Wave Morphology (PWM) and Pulse Arrival Time (PAT).

METHODS

Healthy volunteers (n = 8) were connected to a Non-Invasive Blood Pressure (NIBP) monitor providing fiAP pulse wave and PPG from a clinical transmission-mode SpO finger clip. Biopac recorded 3-lead ECG. A camera placed at a 25 cm distance recorded a video stream (100 fps) of a finger illuminated by a laser diode at 639 nm. A chest belt (Polar) monitored respiration. All signals were recorded simultaneously during episodes of spontaneous breathing and paced breathing.

ANALYSIS

Post-processing was performed in Matlab to obtain SPG and analyze the SPG, PPG and fiAP mean absolute deviations (MADs) on PWM, plus PAT modulation.

RESULTS

Across 2599 beats, the average fiAP MAD with PPG was 0.17 (0-1) and with SPG 0.09 (0-1). PAT derived from ECG-fiAP correlated as follows: 0.65 for ECG-SPG and 0.67 for ECG-PPG.

CONCLUSION

Compared to the clinical NIBP monitor fiAP reference, PWM from an experimental camera-derived non-contact reflective-mode SPG setup resembled fiAP significantly better than PPG from a simultaneously recorded clinical transmission-mode finger clip. For PAT values, no significant difference was found between ECG-SPG and ECG-PPG compared to ECG-fiAP.

摘要

目的

比较散斑容积描记法（SPG）和光电容积描记法（PPG）与无创手指动脉压（fiAP）在脉搏波形态（PWM）和脉搏波传导时间（PAT）方面的差异。

方法

8名健康志愿者连接到无创血压（NIBP）监测仪，该监测仪通过临床传输模式的SpO手指夹提供fiAP脉搏波和PPG。Biopac记录三导联心电图。一台距离手指25厘米的相机记录由639纳米激光二极管照亮的手指的视频流（100帧/秒）。一个胸带（Polar）监测呼吸。在自主呼吸和定频呼吸期间同时记录所有信号。

分析

在Matlab中进行后处理以获得SPG，并分析SPG、PPG和fiAP在PWM上的平均绝对偏差（MAD）以及PAT调制。

结果

在2599次心跳中，fiAP与PPG的平均MAD为0.17（0 - 1）以及与SPG的平均MAD为0.09（0 - 1）。源自心电图 - fiAP的PAT相关性如下：心电图 - SPG为0.65，心电图 - PPG为0.67。

结论

与临床NIBP监测仪的fiAP参考值相比，来自实验性相机衍生的非接触反射模式SPG设置的PWM比同时记录的临床传输模式手指夹的PPG更显著地类似于fiAP。对于PAT值，与心电图 - fiAP相比，心电图 - SPG和心电图 - PPG之间未发现显著差异。
