Which right pressure reading would be an artifact in segmental readings?

A low-thigh reading higher than a below-knee reading would represent an artifact because it contradicts the expected pressure gradient in healthy vascular physiology. In a normal situation, thigh pressures should be higher than or at least equal to the pressures found in the calf (below-knee). If the thigh pressure is lower than a calf pressure, it suggests an abnormality, which could be due to measurement error, equipment malfunction, or the presence of an obstruction affecting blood flow dynamics. Therefore, recording a low-thigh measurement that exceeds the calf pressure does not align with the physiological expectations of blood flow and distribution in the lower extremities, signifying an artifact in the readings.
