Final answer:
The proper deflation rate of a blood pressure cuff is 2-3 mmHg per second to ensure an accurate reading while preventing discomfort or inaccurate blood pressure measurements.
Step-by-step explanation:
The question "how fast to deflate a BP cuff" relates to taking a blood pressure reading, which is a practical skill often taught in health-related college courses. When measuring blood pressure, it is important to deflate the cuff at a proper rate to ensure an accurate reading. The recommended deflation rate for a blood pressure cuff is 2-3 mmHg per second. Deflating the cuff too quickly can result in an inaccurately low systolic reading, while deflating too slowly can result in a venous congestion in the patient's arm and an inaccurately high diastolic reading.
