What can happen if a BP cuff is not applied properly before measurement?

When a blood pressure cuff is not applied properly, it can lead to inaccurate readings. Specifically, if the cuff is either too loose or too tight, the pressure applied during the measurement can be affected. If the cuff is too loose, it may not compress the artery sufficiently, resulting in a lower blood pressure reading than the actual value. Conversely, if the cuff is too tight, it can artificially elevate the reading by restricting blood flow more than necessary.

This variation in the reading due to improper application underscores the importance of correct cuff positioning and tension to ensure that blood pressure readings are as accurate as possible. Accurate measurements are vital for diagnosing and managing various health conditions effectively.
