New technology called Resonance Sonomanometry™ uses acoustic
stimulation for noninvasive continuous blood pressure monitoring
with accuracy within 2%—and no calibration required.
IRVINE,
Calif., July 31, 2024 /PRNewswire/ -- Esperto
Medical™, Inc. a healthtech startup specializing in critical
care and remote patient monitoring, has published study results in
PNAS Nexus evaluating their Resonance Sonomanometry™ (RSM)
technology, a new calibration-free, continuous, noninvasive blood
pressure technology. The study compared Esperto's technology to
reference measurements both in-vitro and in-vivo,
demonstrating accuracy within 2 mmHg (~2%).
The wearable technology is
calibration-free, accurate for all patients, and can be used on
multiple parts of the body
"RSM is an absolute measurement of blood pressure," said Esperto
Chief Technology Officer Raymond
Jimenez. "Studies show that current noninvasive tools, which
measure relative blood pressure can lack accuracy and be hard to
use in many cases. These devices also require time-consuming
calibration—an issue in situations when every minute counts. RSM is
an important advancement over existing tools; it's
calibration-free, accurate for all patients, and can be used on
multiple parts of the body."
Originally developed at the California Institute of
Technology, RSM uses sound waves at different frequencies to
detect resonance in blood vessels. Taking thousands of measurements
per second, it shows blood pressure variations throughout the
cardiac cycle, allowing clinicians to find and correct blood
pressure anomalies quickly and efficiently. Since RSM only uses
sound waves, it can be placed on the arms, legs, and even the neck.
It also requires no calibration, making it easy to set up and
use.
"Accurate blood pressure measurement is essential for high
quality medicine, but the gold standard invasive arterial catheter
has many risks, so can only be used in the critically ill. RSM can
provide continuous blood pressure (and other metrics) to all
patients in a safe and easy to use arm or wrist band," said Esperto
cofounder and Chief Medical Officer, Alaina
Rajagopal, MD PhD. "Cardiovascular disease is the leading
cause of death worldwide. Accurate, continuous, noninvasive,
calibration-free blood pressure, like what we're developing at
Esperto, has the potential to improve medical care for all
patients."
