Cardiovascular disease is the number one cause of death worldwide. At-risk populations need convenient, accessible screening for symptoms whenever and wherever they happen. Stethophone™ by Sparrow makes it possible to collect and collaborate on medical-grade cardiac and pulmonary data using only your smartphone. Our proprietary audio technology records and unlocks the rich diagnostic value hidden in chest sounds. Sparrow is taking cardiac assessment out of the clinic.
Your heartbeat is created by the sound of the heart valves opening and closing and the movement of blood through your system. When valves malfunction and blood rushes erratically or possibly in the wrong direction, the heart emits abnormal sounds. Numerous defects and conditions can be detected by analyzing the sound radiating from the heart as it beats.
Human hearing can detect sounds from 20 Hz to 20,000 Hz. But the sounds made by heart are at the very outer limits of this range of perception. Capturing these using the built-in microphone of a smartphone is just the start of an intricate process of bioacoustic engineering. The barely audible sounds are filtered, isolated, compressed and amplified, enabling Stethophone to pull a tiny, nearly indiscernible audio signal out of an ocean of vibrations. These signals carry a vast amount diagnostic information about the structure and condition of the heart. Sparrow is the first to develop and gain clearance from the U.S. Food and Drug Administration for software that allows a smartphone to be used as a scanner for these cardiac signals – equal to or better than current gold-standard clinical devices.
With Stethophone there is nothing new to carry, charge up or connect. Your phone is your clinical-grade stethoscope – providing enhanced audio, dynamic visualizations of recordings, enhanced analysis, and secure transmission of examinations. Sparrow increases access to detection and diagnosis, improving clinical outcomes worldwide.
As people live longer, more face the challenges of living with heart disease and cardiac complications from other conditions. Early detection, better data and decisive action are essential to extend the lifespan and healthspan of our seniors.
At Sparrow, we are dedicated to make heart disease detection faster, more precise and broadly accessible, leading to prompt treatment and improved clinical outcomes.
This audio clip, captured and visually graphed by Stethophone, presents a case of aortic stenosis, a disease in which the valve between the heart and the aorta, the largest artery in the body, fails to fully open. This condition reduces or blocks blood flow from the heart to the aorta and the rest of the body. Up to 50 percent of patients with severe aortic stenosis die within a year.Hear Stethophone in Action
