Summary
Toe blood pressure measurement is crucial for evaluating lower limb ischemia in diabetic patients. However, cuff width significantly impacts readings, with narrower cuffs yielding higher toe blood pressure values.
Area of Science:
- Vascular Medicine
- Diabetology
- Medical Device Technology
Background:
- Toe blood pressure is vital for assessing lower limb ischemia in diabetic patients.
- Standardization of toe blood pressure measurement methods is lacking.
- Cuff size influence on toe blood pressure in diabetics is understudied.
Purpose of the Study:
- To investigate the impact of cuff width on toe blood pressure measurements.
- To determine if cuff size standardization is necessary for diabetic patients.
Main Methods:
- Compared toe blood pressure using two different cuff widths (2.0 cm vs. 2.5 cm).
- Included eleven diabetic patients without peripheral vascular disease and six healthy controls.
- Measured blood pressure at the upper arm and ankle for comparison.
Main Results:
- Toe blood pressure was 18 mmHg higher with a 2.0-cm cuff compared to a 2.5-cm cuff (p < 0.01).
- A correlation existed between toe circumference and toe blood pressure (r = 0.63, p < 0.05).
- Smaller toe circumferences resulted in lower toe blood pressure readings.
Conclusions:
- Cuff width significantly influences toe blood pressure values in diabetic patients.
- Standardization of cuff width is essential for accurate lower limb ischemia assessment.
- Consideration of cuff width is critical when interpreting toe blood pressure in diabetes.
