Controlled Positional Therapy
Intermittent partial or complete obstruction of the upper airways during the night can lead to serious health issues such as sleep apnea, daytime hypersomnolence, and cardiovascular diseases. Most of these obstructions are caused by gravitational forces in supine position that act on relaxed throat tissue.
Conventional ways of preventing airway obstructions include appliances that make sleeping in supine position uncomfortable and non-invasive ventilators that apply non-physiological continuous positive airway pressures (CPAP) to keep the airways open.

Sara Padilla NeiraWe developed specialized robotic beds that can detect partial or full airway obstructions as well as lying position and perform position changes:
Controlled Positional Therapy for the Treatment of Sleep-Related Breathing Disorders
Positional obstructive sleep apnea is a sleep-related breathing disorder characterized by intermittent cessations of breathing during the night. In most cases, these apnea events happen in supine position. Our two robotic bed platforms detect sleep apneas and perform gentle lateral or longitudinal rotations to prevent users from sleeping in supine position.
Controlled Positional Therapy to Reduce Snoring
Body posture strongly influences snoring activity. The purpose of this project was to exploit this principle and to develop a smart bed that reduces snoring by actively influencing the sleeping position of the user. Particularly, the bed we developed is fully autonomous and allowed for tracking snoring in real-time and reacting in an interactive way by adapting the mattress shape and by providing vibratory stimulation to influence the position of the user.
