Respiratory inductance plethysmography; Penile pulse volume recording; Pulse volume recordings; Segmental pulse volume recordings
PVR, also known as a segmental pressure study, is a non-invasive vascular test involving the use of blood pressure cuffs on your thighs, calves, and ankles, and also on your arms. The cuffs are inflated to compare the blood pressure in your legs to that of your arms.
PCR (polymerase chain reaction) tests are a fast, highly accurate way to diagnose certain infectious diseases and genetic changes. The tests work by finding the DNA or RNA of a pathogen (disease-causing organism) or abnormal cells in a sample.
Plethysmography is used to measure changes in volume in different parts of the body. The test may be done to check for blood clots in the arms and legs. It is also done to measure how much air you can hold in your lungs.
Penile pulse volume recording is a type of this test. It is done on the penis to check for causes of erectile dysfunction.
Most commonly, this test is performed to check blood flow in the arteries of the legs. This is done in people with conditions like hardening of the arteries (atherosclerosis). Atherosclerosis causes pain during exercise or poor healing of leg wounds.

FAQ
How do you record a pulse volume?
- Pulse volume recording (PVR) uses a blood pressure cuff and hand-held Doppler ultrasound device to determine the presence and severity of peripheral artery disease (PAD). The Doppler ultrasound records sound waves that bounce off moving objects, such as blood, to measure speed and flow.
What is the difference between ABI and PVR?
- The ABI helps your physician diagnose arterial disease in the legs, but it does not identify which arteries are blocked. During the exercise testing PVR, the patient walks on a treadmill to try to reproduce the symptoms he or she has experienced.
How do you interpret segmental pressure?
Segmental Pressure Measurement Interpretation:
- Compare pressures vertically, a pressure difference > 20mmHg is indicative of arterial obstruction. A difference > 20mmHg between the brachial pressures indicates hemodynamically significant obstruction.
What is PVR screening?
- A PVR (Pulse Volume Recordings) study is a non-invasive vascular test in which blood pressure cuffs and a hand-held ultrasound device (called a Doppler or transducer) are used to obtain information about arterial blood flow in the arms and legs.
How do you describe pulse volume?
- Volume. The degree of expansion displayed by the artery during the diastolic and systolic states is called volume. It is also known as the amplitude, expansion, or size of the pulse.
What is segmental limb pressure?
- In segmental limb pressures, a technique called Doppler ultrasound is used to evaluate blood circulation in the major arteries in the arms or legs. A probe is passed lightly over different areas of your limbs, directing sound waves at particular arteries.
What are segmental pressure and PVR study?
- PVR, also known as a segmental pressure study, is a non-invasive vascular test involving the use of blood pressure cuffs on your thighs, calves, and ankles, and also on your arms. The cuffs are inflated to compare the blood pressure in your legs to that of your arms.
What is normal pulse volume?
- Pulse/heart rate is the wave of blood in the artery created by the contraction of the left ventricle during a cardiac cycle. The strength or amplitude of the pulse reflects the amount of blood ejected with myocardial contraction (stroke volume). The normal pulse rate range for an adult is between 60-and 100 beats per minute.
How is a PVR performed?
- The test is done with ultrasound. After using the bathroom you will lie flat on the exam table with the surface of your lower abdomen and pelvis exposed. The technician will place gel on the skin over your bladder. The technician will place an ultrasound probe over this area, and make a recording.
How is a PVR test done?
- For this procedure, your provider gives you a local anesthetic (a numbing agent). Then the provider inserts a thin tube called a catheter through your urethra and into your bladder. Any urine left in your bladder drains out through the catheter. The provider then measures the amount that drains out.
How do you perform a PVR test?
- You will be asked to remove any clothing that covers the area(s) being examined. You will then be asked to lie on your back and cover up with a gown or blanket. A sonographer will wrap blood pressure cuffs on your upper and lower legs, your foot, and your arms. Blood pressures will then be taken at each location.
