The SimpleSense Platform is intended for use at home, a healthcare facility, or medical research organization under the direction of a licensed medical professional to record, display, and store the following physiological data: a) 2 leads of Electrocardiogram; b) Respiration rate measured through thoracic impedance; c) Heart Sounds; d) Activity including posture; e) Systolic and Diastolic Blood Pressure and f) other validated data sources. The SimpleSense Platform is intended for use when the licensed medical professional decides to evaluate the physiologic signals of adult patients as an aid to diagnosis and treatment. The SimpleSense Platform is intended to be used by patients at rest with a stationary torso. ECG recordings are indicated for the manual assessment of cardiac rhythm disturbances.
The SimpleSense Platform does not produce alarms and is not intended for active patient monitoring. The SimpleSense Platform is not intended for use as life supporting equipment on high-risk patients such as critical care patients. The SimpleSense Platform is not intended for use in the presence of a pacemaker.
The SimpleSense-BP software application is intended to estimate, display and store blood pressure data on adult patients who are twenty two (22) years and older. The SimpleSense-BP can be used after a clinician determines the user’s hypertension classification via an auscultatory blood pressure cuff measurement. The Blood Pressure algorithm uses patient specific information (age, gender, height and weight) and the blood pressure measurement as inputs. SimpleSense-BP is used to provide blood pressure estimations derived from physiological sensors to qualified medical personnel as a complimentary physiological feature for the purposes of assessing a patient’s cardiac health and variance.
Indications for use as stated in the FDA summary.
