A Powerful New Tool for Health Care Professionals

The DPA Photo-Plethysmograph is a FDA approved device used to measure and analyze pulse waveforms and heart rate. It provides information regarding changes in arterial blood volume and vascular resistance by way of a non-invasive, infrared light fingertip probe.

The measurement probe consists of a light-emitting diode (infrared LED) and a photodiode placed on opposite sides as a light receiver. The light from the LED is transmitted through the tissue at the sensor site. The Photodiode detects the changes in the amount of light absorbed by hemoglobin, which forms the PTG.

The DPA converts the changes of transmitted light into a waveform and displays digital values of pulse rate as well as a graphic display of the pulse waveform and indices on the LCD screen. The DPA also displays the second derivative pulse waveform (Accelerated Plethysmograph - APG) to provide a better evaluation of arterial aging.

By using a PC based DPA expert software program, the DPA is able to measure Heart Rate Variability (HRV) and provide the quantitative analysis of the stress response by time and frequency domains. It indicates the regulation status and balance of the autonomic nervous system.
