Device Story

QardioArm 2 is an OTC, wireless, oscillometric blood pressure monitor for adult spot-checking. Device uses inflatable, detachable upper-arm cuff to measure systolic/diastolic pressure and pulse rate. Input: pressure oscillations during cuff deflation. Output: blood pressure and pulse readings displayed on paired smartphone (iOS/Android). Device detects irregular heartbeats and provides warning signal. Used in home or clinical settings by patients or clinicians. Data transmitted via Bluetooth 5.0 to mobile app. Output informs users of blood pressure status; users instructed to consult physician for hypertensive readings. Benefits include convenient, automated, wireless monitoring of cardiovascular vitals.

Clinical Evidence

Prospective, single-arm paired comparison study per ISO 81060-2:2018. Enrolled 86 adult subjects. Compared QardioArm 2 to reference sphygmomanometer using same-arm sequential method with dual auscultators. Device met all primary endpoints and requirements of ISO 81060-2.

Technological Characteristics

Oscillometric measurement; Bluetooth 5.0 connectivity; rechargeable 3.7V/1000mAh Li-ion battery. Detachable cuffs (8.7-18.5 inch range). Standards: IEC 60601-1 (safety), IEC 60601-1-2 (EMC), IEC 62133-2 (battery safety), IEC 80601-2-30 (sphygmomanometer performance), AAMI TIR69/ANSI C63.27 (wireless coexistence).

Indications for Use

Indicated for adult individuals for non-invasive, fully automatic measurement of systolic/diastolic blood pressure and pulse rate via upper arm cuff (8.7-18.5 inch circumference). Not for diagnostic use.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

The indications for use of the QardioArm 2 are very similar to the predicate device in that they are both fully automatic, oscillometric devices intended for measuring blood pressure and pulse rate in adult patients. The devices are both available OTC and neither device is intended to be used to provide a diagnosis. The differences in the indications are limited to larger cuff sizes being available for the QardioArm 2, and an explicit reference to the ability of the device to detect the appearance of irregular heartbeats during measurement (this feature was also present in the predicate device). These minor differences do not impact the fundamental intended use of the device, which is to measure blood pressure and pulse rate.
