No more arm cuffs? new wrist device could change how we check blood pressure

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Participants must be able to provide informed consent to participate. 2. Participants must be willing and able to comply with all of the study procedures and return for a second visit one week later. 3. Participants must be 22 to 59 years of age. 4. Participants or witnesses must be able to read or write in English. Exclusion Criteria: 5. Participants with compromised circulation, injury, or physical malformation of the equipment test sites or other sensor sites which would limit the ability to test sites needed for the study. (Note: Certain malformations may still allow participants to participate if the condition is noted and would not affect the sites utilized.) 6. Female participants who are known to be pregnant or who are trying to get pregnant confirmed by a visit 1 and, if applicable, visit 2 positive urine pregnancy test, unless the study participants are known to be not of child-bearing potential . 7. Participants with known history of clotting disorders or blood clots, or currently taking a prescription blood thinner. 8. Other known health conditions that will prevent safe participation in the study upon disclosure in Health Assessment Short Form or verbally. 9. Participants suffering from sporadic or sustained cardiac arrhythmias that can lead to weak or unstable pressure pulses including but not limited to tachycardia (heart rate at rest \> 120bpm) and atrial fibrillation. 10. Participants suffering from sporadic or sustained reduction of peripheral perfusion that can lead to weak or unstable pressure pulses including but not limited to: Raynaud's disease, diabetes (Type I and Type II), renal dysfunctions (eGFR \< 60mL / min / 1.73 m2), hyper- / hypothyroidism, pheochromocytoma, arteriovenous fistula, and valvular heart diseases. 11. A wrist circumference below 14 cm or above 23 cm. 12. An upper-arm circumference \<22 cm or \> 42cm. 13. Any subject that, in the opinion of the investigator, does not exhibit any phenotype relevant to the objectives of this study. 14. Any condition or circumstance that, in the opinion of the investigator, may preclude study completion, interfere with accurate data collection, or bias the results, by instance a subject presenting a lateral Blood Pressure difference at screening of more than 15 mmHg for the systolic and/or more than 10 mmHg for the diastolic.
