Pulse Plethysmogram Amplifier
Part #: PPG100C

The PPG100C Photoplethysmogram Amplifier records the pulse pressure wave and provides an indication of blood pressure, blood density or vasoconstriction. Front panel controls allow selection of either absolute or relative plethysmographic measurements.

The PPG100C couples to a photoplethysmogram (PPG) transducer (TSD200 or TSD200C*) to record the Blood Volume Pulse (BVP) waveform via optical (photoplethysmogram) methods.

The PPG100C also has the capability to interface to a wide range of commercially available optical probes. Specifically, optical transducers for SpO2 can easily be used with the PPG100C, via the TCIPPG3 snap on interface.

The PPG100C is part of a complete research system, interfacing with the MP150 data acquisition and analysis platform and AcqKnowledge software, allowing advanced analysis for multiple applications and supporting acquisition of a broad range of signals and measurements. For PPG with MRI applications, see PPG100C-MRI.

Details

Compatibility


 Each PPG100C requires one photoplethysmogram transducer:

  • TSD200 with Velcro for easy attachment to finger OR
  • TSD200C* with ear clip

The TSD200 consists of a matched infrared emitter and photo diode detector, which transmits changes in infrared reflectance resulting from varying blood flow. Blood is highly reflective of near infrared light wavelengths, due to the heme subunit of hemoglobin. When the PPG transducer is placed on the skin, in proximity to capillaries, the reflectance of the infrared light from the emitter to the detector will change in accordance to capillary blood volume. The PPG waveform peaks when capillary blood volume is maximized.

 The TCIPPG3 interface adapter plugs into the front of the PPG100C and allows it to work with SpO2-type probes that terminate in a 9-pin D female connector (such as those from Nonin®). The visible light transmitter and receiver of the probe is employed to establish a very high quality, high signal/noise ratio, transmissive, photoplethysmogram signal, suitable for evaluating PPG signal characteristics. Note that this configuration does not provide SpO2 output, but rather a highly-detailed PPG waveform versus time. Probes are available for fingers, toes, earclip, and universal attachment. BIOPAC probes compatible with the TCIPPG3/PPG100C combination include SpO2 transducers TSD124A, TSD124B and TSD124C. The TCIPPG3 also supports use of the OXY100E-200 extension cable.

* The older model TSD200B with adhesive collars is no longer sold but works with the PPG100.
