Falcon Pro Physiologic Doppler System
Falcon Physiologic Doppler System for ABI/PVR
IMIUSA’s goal is to raise the bar for quality in clinical diagnosis of peripheral vascular disease and to promote both local and global health.
Image Monitoring USA offers an entirely automatic clinical ABI PVR machine with up to ten readings simultaneously with straightforward one-button control. Pulse Volume Recording (PVR) is a pneumo-plethysmography test that is widely used for non-invasive diagnosis of lower extremity peripheral arterial disease (PAD).
As a PVR machine, the Falcon allows immediate pulse volume recording that can be completed rapidly for each measured site.
PVR measurements with the Falcon vascular diagnostic system can be performed either sequentially for one site after the other, bilaterally for simultaneous PVR measurements on similar right/left leg sites, or simultaneously on as many as 10 sites in parallel.
The user is only required to place the color-coded pressure cuffs around each target site on both legs. Then, any PVR protocol needs to be selected. Now the test is ready to start and can be completed in just a couple of minutes.
All PVR settings can be pre-configured in the protocol, so only a single button can be used to complete the test. The user can modify the preferred target inflation pressure, sweep time display, scale, or filter.
Many other Falcon features and options, such as automatic simultaneous measurements or display of contralateral results, are designed to simplify the use of the Falcon PVR physiologic system followed by a complete clinical diagnosis in a fast and efficient way.
While the diagnosis of pulse volume recording is primarily qualitative, the Falcon also provides a range of quantitative parameters, including the waveform amplitude, rise time, or heart rate. Additional calculations such as the RAR or waveform slope are also available.

Additional Information
What is Ankle Brachial Index?
An essential test for identifying peripheral vascular disease is the ankle-brachial index (ABI Test). The index calculates a ratio by comparing the systolic blood pressures in the arms and legs, which can indicate different degrees of peripheral vascular disease.
What is PVR?
Pulse Volume Recording is an air plethysmography waveform analysis test used to detect the segmental volume changes in the limb resulting from the flowing blood as a function of the cardiac cycle. This test is usually performed with a Falcon PVR machine.
ABI/PVR Test Expected Results
By dividing the blood pressure in an ankle artery by the blood pressure in an arm artery, medical professionals can determine ABI. If this ratio is less than 0.9, peripheral arterial disease may be present. An ABI outcome between the range of 0.91 to 99 is acceptable, but it may indicate that your PAD is on the edge. If your ABI ratio is greater than 1.4, it may be a sign that you have diabetes or advanced age, which causes stiff blood vessels in your limbs. Whereas, an ABI ratio of 1.0–1.4. is considered normal and means you don’t have PAD.
How to Measure ABI?
After the patient has been at rest laying horizontally with the torso and face upward for 10 minutes, the ABI is carried out by recording the systolic blood pressure from both the brachial arteries and the dorsal pedis and posterior tibial arteries. An inflated cuff, identical to the one used in the hospital or clinic, is used by the technician to take the blood pressure in each of your arms.
The measuring sequence is to start with the right arm, then the right leg, then the left leg, and finally the left arm. This is because the blood pressure may fluctuate during the test; therefore, the two arm pressures at the start and end of the exam offer some quality control. The systolic pressures are usually measured with the aid of handheld 4, 8 or 10-MHz Doppler equipment.
ABI/PVR Medical Abbreviation
ABI and PVR are the most used medical abbreviations by people in this field but, many common people are not aware of them.
- ABI stands for Ankle-Brachial Index.
- PVR stands for Pulse Volume Recording.
