Monitoring Humidity for Diabetic Foot Ulcers | Sleep Apnea, more specifically Obstructive Sleep Apnea (OSA), is a condition characterized by
blockage of the airway by soft tissue, resulting in frequent episodes of interrupted breathing
throughout the sleep cycle. Residual effects of untreated OSA are often detrimental to patient
health, with the most common being excessive daytime sleepiness, psychological and cognitive
decline, heart tissue damage, hypoxia, and death1 . The most common treatment for OSA is
Continuous Positive Airway Pressure (CPAP) therapy. During CPAP use, the upper respiratory
tract is ventilated with a constant pressure flow to allow continuous airway expansion necessary
for unobstructed breathing. Currently there are approximately 8 million adult CPAP users in the
US—with anticipated growth of 8-9% users annually2 . Of these consumers, 13 long and
short-term CPAP users were interviewed exclusively for the purpose of this project. With
knowledge gained through these interviews, market research, and published and personal
experiences with OSA, surveys were generated and dispersed to determine the primary
problems associated with CPAP usage. From this, a universal concern among interviewees was
determined—a lack of accurate, continuous validation of proper oxygenation with minimal
discomfort. With consumer needs and concerns in mind, SleepSound Therapeutics has created
a cost-effective, durable device which accurately tracks apneatic events using biological
measurements during sleep. Predicate devices are expensive, inaccurate and uncomfortable
solutions. Our novel device is a potential solution capable of validating the efficacy of oxygen
supplementation and/or CPAP therapy. We have developed an affordable, comfortable device
which accurately measures oxygen saturation throughout the sleep cycle and presents this data
in an easy to-interpret format.
