Title: Keerthana Natarajan: Innovator in Mobile Health Technology

Introduction

Keerthana Natarajan is a prominent inventor based in East Lansing, MI (US). She has made significant contributions to the field of mobile health technology, particularly in the area of blood pressure measurement. With a total of 2 patents, her work is paving the way for more accessible health monitoring solutions.

Latest Patents

One of her latest patents focuses on mobile device applications to measure blood pressure. This innovative method does not require specialized equipment, such as inflatable blood pressure cuffs. Instead, it allows measurements to be taken from arterial locations within a user's finger using standard consumer mobile devices. The devices can guide users to press their fingers on the screen at precise locations, ensuring accurate measurements. Visual guidance, such as finger silhouettes and animations, enhances the user experience. Pressure sensitivity and optical camera readings are utilized to calculate blood pressure effectively.

Another notable patent involves central blood pressure monitoring via a standard automatic arm cuff. Current oscillometric devices maintain cuff pressure at a constant level to acquire a pulse volume plethysmography (PVP) waveform. Keerthana's physiologic method advances central BP measurement by applying a patient-specific approach to estimate brachial BP levels from a cuff pressure waveform. This method employs a wave reflection model to define a variable transfer function, which is then used to derive central BP from the calibrated waveform.
