Blood Pressure Measured on the Arm : Bare Arm Versus a Speleological Suit Sleeve in Patients From Grenoble Alpes University Hospital

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

Inclusion Criteria: * Patient over 18 years admitted to the emergency department of Grenoble University Hospital * National health insurance coverage or an equivalent form of coverage Exclusion Criteria: * Physical or technical inability to collect BP upon the patient's admission at ED (wounds or trauma to the arms) * Technical impossibility to set up the tested sleeve (incompatible arm size) * Patient with a medical contraindication to repeated blood pressure measurements on both arms * Patient who received antihypertensive treatment within the hour prior to measurements * Staff with hierarchical family or friendly ties to the principal investigator * Inability to provide informed consent because of impaired communication in French * Persons covered by Articles L1121-5 to L1121-8 of the Public Health Code * The patient already enrolled in the study * Objection by the subject to the study
