To determine the Ankle-Brachial Index (ABI), the correct formula used is to divide the ankle systolic pressure by the brachial systolic pressure. In this case, the ankle systolic pressure is 90 mmHg, and the brachial systolic pressure is 120 mmHg. Calculating the ABI involves the following calculation: ABI = Ankle Systolic Pressure / Brachial Systolic Pressure ABI = 90 mmHg / 120 mmHg = 0.75 An ABI value of 0.75 indicates a specific ratio that is useful in assessing peripheral arterial disease. This value falls within a range that suggests moderate arterial insufficiency, which should be noted by healthcare professionals during assessments. Understanding the significance of the ABI is crucial for wound care associates, as it helps in diagnosing conditions related to compromised blood flow, which is critical in wound healing and management.
