The acronym PPG stands for photo plethys mogram, where photo denotes light, platysma denotes volume change, and gramme denotes graph.
In order to understand the fluctuation in heart rate, PPG (photoplethysmography), which stands for photoplethysmography, refers to a high precision light sensor used to detect blood flow volume.
Heart rate and rhythm detection has traditionally been done with the aid of ECG (Electrocardiography) sensors. ECG sensors cannot be utilized to monitor heart rate when the body is moving because they are cumbersome.
Scientists developed PPG technology at that time. The goal of developing photoplethysmography (PPG) technology was to create compact, wearable heart rate sensors.
PPG sensors are small but nonetheless produce results that are almost identical to those of an ECG sensor. This makes it possible to measure heart rate and heart rate variability constantly and reliably, even during vigorous physical exercise.
Due to its small size, PPG technology has made it simple to put sophisticated heart rate measurement technology in everyone’s hands.
The Global PPG Healthcare Sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Monitoring of the Vital sign launched ECG, PPG and PTT system A type of chest recording the electrocardiographic (ECG or EKG) activity of the heart in real time.
By adhering the electrode to the skin surface of the human body, it is possible to record the heart’s potential transmission.
Electrocardiogram results are typically shown as waves, including P wave, QRS wave group, and T wave. Atrial contraction is symbolized by the P wave, ventricular diastolic by the QRS wave group, and atrial contraction by the T wave.
The heart rate can be expressed as the amount of time between each R wave. The decreased heart rate is indicated by the shorter RR interval.
The process of measuring ECG signals frequently entails affixing sensors to various body areas.
A non-invasive technique called photoplethysmography (PPG) uses photoelectricity to track changes in blood volume in live tissue.
Each time a heartbeat occurs, the contraction and expansion of blood vessels will alter the wavelength of light that reaches the skin surface of the finger.
or the light’s reflection When the light travels through the skin tissue and reflects back to the light sensor, it is attenuated.
The constant on light absorption is muscle, bone, veins, and other basic organization under the skin. The absorption of light can alter, however blood is different because of arterial blood flow. When light is converted to electrical impulses.
