photoplethysmogram

Example:The photoplethysmographic signal was analyzed to determine the patient's cardiac output.

Definition:The electrical signal generated by a photoplethysmograph used to assess blood volume changes.

Example:Continuous PPG monitoring helped to detect the patient's circulatory issues early.

Definition:The continuous measurement of blood volume changes through skin or tissue using a photoplethysmogram.

Example:The new device utilized advanced photoplethysmography techniques to improve its accuracy.

Definition:The medical science and practice involving the use of photoplethysmography to measure blood flow.

Example:Analyzing the PPG waveform can help identify abnormal heart rhythms.

Definition:The graphical representation of a photoplethysmogram, showing the cyclic changes in light absorption due to blood volume pulsation.

Example:Wearable fitness trackers often include a photoplethysmogram sensor to monitor heart rate and blood pressure.

Definition:A sensor used to detect and record the photoplethysmogram signal for medical monitoring.
