NCT04869826

Brief Summary

The objective of this study is to calibrate the blood pressure measurements of the Pulsewave Health Monitor (PAD-2A) device to be within 5±8 mmHg of the average of the dual-observer measurements via an aneroid sphygmomanometer (reference device), as per the methodology described in the ISO 81060-2: AMD\_2020 protocol.

Outcome Measures

Primary Outcomes (4)

  • Systolic Pressure

    Non-invasive Pulsewave Health Monitor (PAD-2A) wrist cuff blood pressure device (mmHg)

    From the start of cuff inflation to the end of cuff deflation (approximately 60 seconds)

  • Systolic Pressure

    Simultaneous auscultatory blood pressure measurements by 2 trained observers

    From the start of manual inflation of the upper arm blood pressure cuff to the end of (manual) deflation of the upper arm blood pressure cuff (approximately 30-60 seconds)

  • Diastolic Pressure

    Non-invasive Pulsewave Health Monitor (PAD-2A) wrist cuff blood pressure device (mmHg)

    From the start of cuff inflation to the end of cuff deflation (approximately 60 seconds)

  • Diastolic Pressure

    Simultaneous auscultatory blood pressure measurements by 2 trained observers

    From the start of manual inflation of the upper arm blood pressure cuff to the end of (manual) deflation of the upper arm blood pressure cuff (approximately 30-60 seconds)

Study Arms (1)

Outpatients Complicated Hypertension Clinic

This study population consists of approximately 200 adult male and female participants (≥ 19 years of age; minimum 30% male/female). Participants will be recruited from eligible patients who are referred to the Complicated Hypertension Clinic at the Saint John Regional Hospital (SJRH) as well as non-patient participants who are willing to volunteer to consent to participate in the study.

Device: Pulsewave Health Monitor (PAD-2A) Device

Interventions

This is an observational, comparison study of blood pressure measurements. The objective of this study is to calibrate the blood pressure measurements of the Pulsewave Health Monitor (PAD-2A) device to be within 5±8 mmHg of the average of the dual-observer auscultatory blood pressure measurements via an aneroid sphygmomanometer (reference device), as per the ISO 81060-2: AMD\_2020 universal protocol.

Sampling MethodNon-Probability Sample
Study Population

For this study, we will recruit and consent approximately 200 adult male and female patient participants (≥ 19 years of age; minimum 30% male/female) who are referred to the Complicated Hypertension Clinic at the Saint John Regional Hospital (SJRH) and non-patient participants who are willing to volunteer to consent to participate in the study. Eligibility of participants for this study is based on the inclusion and exclusion criteria as per the ISO 81060-2: AMD\_2020 protocol, as described below.

You may qualify if:

  • Adults ≥ 19 years of age (minimum 30% male/female)
  • Wrist circumference between 13.5 cm. - 23 cm. (5.3 in. - 9.1 in.):
  • Specifically for this test device, the wrist size of the consented participants will be distributed accordingly for a Gaussian distribution:
  • Lowest Octile: ≥ 13.5cm to \< 14.7cm Lower Quarter: ≥ 13.5cm to \< 15.9cm Lower-Middle Quarter: ≥ 15.9cm to \< 18.3cm Upper-Middle Quarter: ≥ 18.3cm to \< 20.7cm Upper Quarter: ≥ 20.7cm to ≤ 23.0cm Highest Octile: ≥ 21.9cm to ≤ 23.0cm
  • ● Willing to volunteer to participate and to sign the study specific informed consent form

You may not qualify if:

  • Wrist circumference less than 13.5 cm. (5.3 in.) or greater than 23 cm. (9.1 in)
  • Hand or body tremors
  • Irregular heart rhythm (bigeminy, trigeminy, isolated ventricular premature beat (VPB), atrial fibrillation)
  • Korotkoff sound K5 not audible
  • Pregnant
  • A musculoskeletal disorder that prevents a non-invasive device to be inflated/deflated on the arm
  • Unwilling to volunteer to participate and to sign the study specific informed consent form
