Newer Technology in OSA Management
Dr. Abhinav Chaudhary

Pointing out that sleep tracking gadgets are on the rise, Dr. Abhinav Chaudhary explained that several physiological
signals can be exploited for the diagnosis and observation of obstructive sleep apnea (OSA) (Figure 1). The
presentation went on to explain the features of home sleep apnea test (HSAT), cardiac-based measures, acoustic
devices, wearable devices, and smart beds for monitoring OSA. It also explained the usefulness of biomarkers in the
detection of OSA (Figure 2).

The presentation then went on to explain the management of OSA and explained continuous negative external
pressure (cNEP) (Figure 3), variable negative external pressure (vNEP), intraoral electrical muscle stimulation and
neurostimulation devices (Figure 4). After explaining the evidence and features of these devices, the presentation
concluded by noting that OSA is a global concern and is an underdiagnosed condition due to lack of awareness, the
complexity of diagnosis, and cost. The modern methods described in the presentation are constructed based on the
considerations of portability, cost-effectiveness, and ease in usability, but have not yet reached that goal. Dr. Chaudhary
concluded his presentation by noting that futuristic methods of detection such as nanotech-based, 9 G DNA technology,
3D facial photography, and AI-based methods have the potential to be highly proļ¬cient in detecting OSA.
