2. Penile plethysmography - Wikipedia

   en.wikipedia.org/wiki/Penile_plethysmography

   Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal.The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and ...

   Because blood flow to the skin can be modulated by multiple other physiological systems, the PPG can also be used to monitor breathing, hypovolemia, and other circulatory conditions. [5] Additionally, the shape of the PPG waveform differs from subject to subject, and varies with the location and manner in which the pulse oximeter is attached.

5. Ultrasonic flow meter - Wikipedia

   Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...

7. Angiography - Wikipedia

   en.wikipedia.org/wiki/Angiography

   For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. Images in this case are usually taken at 2–3 frames per second, which allows the interventional radiologist to evaluate the flow of the blood through a vessel or vessels. This technique "subtracts" the bones and ...

8. Vaginal photoplethysmograph - Wikipedia

   en.wikipedia.org/wiki/Vaginal_photoplethysmograph

   The direct current signal is a measure of vaginal blood volume (VBV) and reflects the total blood volume in the vaginal tissues. [ 3 ] [ needs update ] The alternating current signal is a measure of vaginal pulse amplitude (VPA) and reflects the pressure change within the blood vessels of the vaginal wall associated with each heartbeat. [ 3 ]

9. Emergency bleeding control - Wikipedia

   The pressure on the wound constricts the blood vessels manually, helping to stem blood flow. When applying pressure, the type and direction of the wound may have an effect, for instance, a cut lengthways on the hand would be opened up by closing the hand into a fist, whilst a cut across the hand would be sealed by making a fist.
