Blood pressure (BP) is an essential physiological parameter for assessing patient condition. In pre-hospital emergency situations it is measured at the arm over the patient's clothing when the patient cannot be undressed.
However there is no study proving the reliability of this measurement compared to measurement according to recommendations (blood pressure cuff).
This lack of proof could lead to misinterpretation when measurement conditions are not optimal.
