Blood Pressure
Conditions
Brief summary
Up to 185 adult test subjects to evaluate blood pressure measurement accuracy and stability of the Polso™ Watch compared to a reference blood pressure measurement.
Detailed description
The purpose of this validation study is to assess, in an adult population, the three fundamental clinical tests: 1. Blood pressure measurement accuracy (accuracy test) 2. Measurement accuracy after blood pressure change (change test) 3. Blood pressure measurement accuracy throughout the specified stability-period (stability test) To provide evidence that the device can track changes in blood pressure, this study includes study conditions that specifically induce changes in blood pressure.
Interventions
DEVICEPolso™ Watch blood pressure measurement compared to a reference blood pressure measurement
The referenced blood pressure measurements are taken by dual auscultators.

Inclusion criteria
* Subjects must be able to understand and provide an informed consent to participate. * Subject must be willing and able to comply with the study procedures. * Subject must be ≥ 50 and \<80 years of age. * At least 30% of subjects shall be male and at least 30% of subjects shall be female. * Subject with an arm circumference in the range of the reference device cuff selection. * Subject with a wrist circumference in the range of the IMD wrist size selection.
Exclusion criteria
* Subjects with physical characteristics that (e.g. tattoos, scarification, unusual bone structure) may prevent proper application of the device under test. * Subject is evaluated by the investigator or clinician and found to be medically unsuitable for participation in this study. * Patients with known sustained or non-sustained ventricular/atrial arrhythmia (Ventricular tachycardia, supraventricular tachycardia, atrial fibrillation, bigeminy, and trigeminy), and left bundle branch block. * Patients with implantable defibrillators, pacemakers, neurostimulators, or other implantable or worn devices which may interfere with the Polso™ Watch or be affected by the Polso™ Watch in normal operation and use. * Patients with known Parkinson's disease, essential tremor, convulsive disorders, or other disorder which prevents them from keeping their forearm at rest. * Patients with known elevated levels of Methemoglobin (MetHb) or Carboxyhemoglobin (COHb), or with anomalous hemoglobin. * Patients with known severe anemia. * Subjects with clinically apparent compromised circulation or peripheral vascular disease * Subjects with clotting disorders or taking anticoagulants other than daily small doses of aspirin or similar * Subjects that cannot tolerate sitting for up to 1 hour. * Subjects that cannot perform the required blood pressure induced change procedure. * Subject with a blood pressure (and other physiological parameters) demographic that has already been filled. * Subjects with a known allergy to plastic, metals, and/or rubber. * Subjects with a history of skin fragility or breakdown, such as ecchymosis or lacerations, affecting the upper extremities that would affect the application of non-invasive blood pressure cuff. * Subjects who are pregnant. * Subjects with BMI \>35 * Subjects with BMI \<20 * Subjects who gained or lost of \>10% of their weight over a period of the last 6 months
