20PlethysmographyFeaturesIndirect Blood PressureRecordings Q17Record indirect blood pressure with a blood pressure cuff(TSD120) and a contact microphone (TSD108) placedover the brachial artery. Increase cuff pressure to occludethe vessel and slowly release it; as the pressure signaldrops, the microphone will record the Korotkoff sounds.Easily determine systolic and diastolic BP with themeasurement tools.Continuous noninvasive blood pressure measurement is alsopossible — see the NIBP application on page 30.Record variations in appendage size as a result ofblood circulation or pressure changes and performindirect blood pressure measurements, using theausculatatory or oscillometric technique. Combineoptical plethysmographic recordings with standardsphygmomanometer-based pressure measurements.Perform sexual arousal studies using a penile orvaginal plethysmograph transducer.• Indirect Blood Pressure Recordings(Auscultatory & Oscillometric)• Sexual Arousal Studies• Blood Volume• Regional Blood Flow• Venous Capacitance• Venous Outflow• Venous Compliance• Pulse Transit Time & Relative BP MeasurementSexual Arousal StudiesMonitor a variety of different psychophysiologicalparameters, including vaginal plethysmography(TCIPPG1), penile plethysmography (TCI111/112),temperature, electrodermal activity (GSR), respiration,and pulse. On-line calculation channels allow users tomonitor pulse rate, respiration rate, pulse amplitude, andarea under the pulse curve.
