Abstract: An inaccurate blood pressure (BP) measurement can result if a person is not thermally comfortable during a cuff BP measurement. For example, an inaccurate BP measurement can result if a person feels cold when his or her upper extremity that wears the BP measurement cuff is exposed to a low ambient temperature during a BP measurement. Although a person can wear thermally comfortable clothing, the person's upper extremity must be exposed to the ambient temperature during a cuff BP measurement. A cover, such as a fabric blanket, thermo-regulated blanket, electric blanket, plastic tube, etc., for a BP measurement cuff and/or for a person's upper extremity that wears the BP measurement cuff can improve the person's thermal comfort and can stabilize cuff BP measurements. In addition, warm or cool conditioned air with an appropriate level of humidity can be introduced into the cover to make the person even more thermally comfortable.
