Patent number: 11766222Abstract: A method of determining a fitness level of user with a physiological sensor. The method includes measuring a physiological value of the user with the physiological sensor, correlating the measured physiological value into a measurement of the user's respiratory rate and tidal volume, calculating a second respiratory rate value using the measured tidal volume, calculating a breathing efficiency (BE) ratio based on a comparison of the user's measured respiratory rate and the calculated second respiratory rate value, correlating the calculated BE ratio to a predetermined threshold, and assigning a classification to the user based on the calculated BE ratio. The classification is indicative of the user's respiratory function performance.Type: GrantFiled: March 14, 2023Date of Patent: September 26, 2023Assignee: RTM Vital Signs LLCInventors: Nance K. Dicciani, Denise L. Devine, Magdalena K. Bosak

Patent number: 11759114Abstract: An implantable extravascular pressure sensing system includes a cuff including a first brace portion affixed to a second brace portion and defining a longitudinal axis therebetween. The first brace portion defines a fluid chamber, the fluid chamber defining a recessed aperture. A first lateral restraint and a second lateral restraint are disposed between the first brace and the second brace, the first lateral restraint and the second lateral restraint being configured to be displaceable in a direction orthogonal to the longitudinal axis. A diaphragm is coupled to the fluid chamber and sealing the recessed aperture. A fluid is disposed within the fluid chamber for exhibiting a hydraulic pressure in communication with the diaphragm. A pressure sensor is coupled to the first brace portion, the pressure sensor being configured to measure a change in the hydraulic pressure when a force is imparted on the diaphragm.Type: GrantFiled: June 4, 2021Date of Patent: September 19, 2023Assignees: RTM Vital Signs LLC, Thomas Jefferson UniversityInventors: Josiah Verkaik, Jeffrey I Joseph

Patent number: 11622728Abstract: A method of determining a fitness level of user with an acoustic measurement device configured to measure sound associated with airflow through a mammalian trachea. The acoustic measurement device is in communication with a controller having processing circuitry. The method includes correlating the measured sound into a measurement of the user's respiratory rate and tidal volume; calculating a second respiratory rate value using the measured tidal volume; calculating a breathing efficiency (BE) ratio based on a comparison of the user's measured respiratory rate and the calculated second respiratory rate value; correlating the calculated BE ratio to a predetermined threshold; and assigning a classification to the user based on the calculated BE ratio.
