Product Information

Specifications

• Product Name: simpleABI-QTM System
• Model Number: MAN-0024-C

Product Usage Instructions

The simple ABI-Q Procedure (Basic)

1. Opening the exam:
   • On the computer desktop, double click the simpleABI icon.
   • When the program opens, select File > New > New ABI-Q Report.
2. Attaching cuffs:
   • With the patient in the supine position, wrap 10cm cuffs at each ankle.
   • Attach the hose from the PVR control unit to the right cuff.
3. Obtaining Waveforms:
4. On the screen, click on a respective Waveform Field in the exam.
5. If you are not satisfied with the waveform, leave the cuff inflated (in the green) and click on the Waveform Field and then Get Waveform buttons again to overwrite the previous waveform. When complete, release the air in the cuff.
6. Under each waveform will be the calculated ABI-Q.
7. When finished, save the report.

The simple ABI-Q Procedure (Exercise)
Background: Approximately 30% of patients with PAD symptoms but a normal resting diagnosis will have an abnormal diagnosis after exercise. Your practice will improve the clinical diagnosis of patients with PAD by implementing an exercise program in your vascular diagnostic collection.

1. Have the patient perform an exercise to increase blood flow to the extremities.

INSTRUCTION

Please Read the User Manual first: This is a quick reference guide
Exam Purpose: The ABI-Q procedure is a 1-2 minute exam to quickly and effectively assess the lower extremity arteries for peripheral artery disease. It utilizes PVR waveforms at both ankles.
Background: The ABI-Q exam is a test that examines arterial waveforms to determine the need for further vascular evaluation. The test is intended to aid in the diagnosis of peripheral artery disease, but does not provide a diagnosis in and of itself

Basic

Opening the exam: On the computer desktop, double-click the simple ABI icon. When the program opens select File New New ABI-Q Report. The report will open and you can enter patient information, risk factors, symptoms, ICD codes, etc.
Attaching cuffs: With the patient in the supine position, wrap 10cm cuffs at each ankle. Attach the hose from the PVR control unit to right cuff as shown below.
NOTE the image is reversed as if you are looking at the patient lying down.

Obtaining Waveforms:

1. On the screen, click on a respective Waveform Field in the exam.
2. Using the bulb, inflate the cuff to about 80 mmHg. Deflate the cuff down to about 65mm and stop. You will see a visual guide bar above the Get Waveform button on the screen. The center section of the target pressure guide will turn green (if the guide is red, then pressure is too low or too high). When a constant green, click the Get Waveform button. PVRs require patient cooperation; limb motion affects the waveform. Patients should be instructed not to move or talk during this test. The waveform will appear and when complete the pop-up will disappear and the waveform will be present in the Waveform Field in the exam.
3. If you are not satisfied with the waveform, leave the cuff inflated (in the green) and click on the Waveform Field and then Get Waveform buttons again to overwrite the previous waveform. When complete, release the air in the cuff.
4. Under each waveform will be the calculated ABI-Q.
5. When finished, save the report.

Exercise

Background: Approximately 30% of patients with PAD symptoms but a normal resting diagnosis will have an abnormal diagnosis after exercise. Your practice will improve the clinical diagnosis of patients with PAD by implementing an exercise program in your vascular diagnostic collection.

1. Have the patient perform an exercise to increase blood flow to the extremities
2. PREFERRED* have the patient perform 50 dorsiflexions (raising the toes towards the shin).
3. Have the patient perform 50 toe raises (or until exhaustion).
4. Hall walking or treadmill walking may be performed until exhaustion or for up to 5 minutes.
5. Have the patient quickly lie down (if standing or walking) and perform the exam as described above in the basic exam.
6. Note in comments or interpretation field what exercise was performed, exercise duration, etc.
7. When finished, save the report.

Waveform Interpretation

Interpreting Waveforms:

• Additional information can be obtained by analyzing the PVR waveforms.

Normal Waveforms:

• Normal PVR waveforms have a sharp upslope and a prominent reflected wave in late systole or dicrotic notch.

Abnormal Waveforms:

• Moderately abnormal PVR waveforms will cause the waveform to broaden and the reflected wave (dicrotic notch) will not be present.
• Severely abnormal PVR waveforms have little to no amplitude, or even appear as a ‘flatline’.

Final Interpretation

Vascular Diagnosis:

• The simpleABI-Q is an aid in the diagnosis of peripheral vascular disease but does not provide a diagnosis in and of itself. After the examination, the physician should consult both the ABI-Q guidelines in conjunction with the waveform interpretation to determine the presence or absence of PAD. Care should be taken to look at each side individually.
• ABI-Q guidelines are shown below.

Helpful Hints

Cuff technique hints:

• Wrap the cuff snugly.
• While wrapping cuffs, don’t let the patient try to help by lifting their leg – as soon as they relax their muscles the cuff will become loose.
• Placing a pillow under the patient’s heels may aid the examination.
• Have the patient remain as still and quiet as possible while taking the waveforms.
• If the patient has tremors that interfere with the waveform, having them do a few dorsiflexions with their toes before taking the waveform can sometimes help.
