Do you have to remove clothing for an upper-arm measurement?
Admittedly, it's a bit annoying and sometimes leads people to simply "forget" to take their blood pressure: having to uncover the upper arm when you want to measure it. The recommendation says this is necessary to get correct blood pressure readings. But is that really true?
Is it really necessary to remove clothing for home measurements with an automatic upper-arm device? Is pushing or rolling the sleeve up enough, or can the cuff be placed over the clothing?
Pulling or rolling the sleeve up is not recommended. It should only be done if it doesn't constrict the upper arm at all the sleeve should still sit loosely. That's not possible with most garments. If the sleeve already compresses the arm over the measurement point (even with only slight pressure), it can affect the measurement and lead to incorrect results.
For measurements over clothing, if values are normal or high-normal and the clothing is rather thin, no relevant deviations are expected. However, you should make sure that the clothing doesn't create folds under the cuff. If blood pressure is elevated, using an automatic blood pressure device can give distorted readings. In plain terms, this means that blood pressure can be measured over clothing with an automatic device like those usually used at home. This applies especially when measuring over a thin T-shirt or shirt. The thicker the garment, the more likely measurement errors become. If higher values are expected for example because the user has hypertension measuring on the bare arm is always the safest option for accuracy.
At the doctor's office or in emergency services, measurements are usually taken with a mechanical device and a stethoscope. Blood pressure can be determined in three ways: the Korotkoff sounds are heard through the stethoscope, oscillations can be seen on the manometer, and if the environment makes it impossible to hear the sounds the systolic (upper) pressure can be determined by feeling the pulse. Therefore, applying the cuff over clothing is even less problematic here especially when speed is important.
