Automated Noninvasive Blood Pressure – Human

The NIBP100D Noninvasive Blood Pressure System automatically records noninvasive blood pressure. The NIBP100D system attaches to the fingers of a human subject to output a continuous noninvasive arterial pressure (CNAP) signal. The system will work for short and long-term studies that demand several hours of monitoring. Combine the blood pressure signal with a variety of […]

Blood Volume

Measure variations in blood flow indirectly via changes in opacity with the plethysmogram transducer for tethered, wireless and MRI applications. Typically, a blood volume pulse (BVP) transducer—otherwise known as a pulseplethysmogram or photoplethysmogram (PPG) transducer—is attached to the finger or toe to record the peripheral pulse. AcqKnowledge® will calculate measurements on a beat-by-beat basis. Pulse rate (heart […]

Indirect Blood Pressure Recordings

Record indirect blood pressure with a blood pressure cuff (TSD120) and a contact microphone (TSD108) placed over the brachial artery. Increase cuff pressure to occlude the vessel and slowly release it; as the pressure signal drops, the microphone will record the Korotkoff sounds. Easily determine systolic and diastolic BP with the measurement tools. Continuous noninvasive blood […]

Pulse Transit Time (PTT), Pulse Wave Velocity (PWV) and Pulse Wave Amplitude (PWA)

Pulse Transit Time (PTT) is the time it takes the Pulse Pressure (PP) waveform to propagate through a length of the arterial tree. The pulse pressure waveform results from the ejection of blood from the left ventricle and moves with a velocity much greater than the forward movement of the blood itself. To measure pulse […]

Regional Blood Flow

To analyze regional blood flow, occlude the venous return with the blood pressure cuff (TSD120) and measure the swelling of the distal portion of the limb with a mercury strain gauge, otherwise known as a strain gauge plethysmograph (SPG). This Pneumo Plethysmography (PnuPG) test allows users to monitor changes from a baseline reading and compare […]

Sexual Arousal Studies

Monitor a variety of physiological sexual arousal parameters from male and female subjects including penile plethysmography (phallometry) using a TSD205 PNPG transducer or vaginal plethysmography (VPG) using a TSDVPG transducer, temperature, EDA, respiration, and pulse. Monitor pulse rate, respiration rate, pulse amplitude, and area under the pulse curve on-line with calculation channels. Present images, or […]
