Saans is a low cost and easy to use manual Continuous Positive Airway Pressure (CPAP) device, which is used to maintain a constant pressure air flow to keep the lungs of newborns and infants open during troubled breathing. Saans is vital for continuous breathing support for infants with troubled breathing during transportation to advanced care facilities and in a temporary maintenance of respiratory support in instances where electric CPAP machines cannot work. The product being an entirely mechanical assembly operates without any power and could be used by a minimally trained person without any external supervision from a trained medical professional, unlike electric CPAP machines. Saans will provide high quality, low skill respiratory support at a lesser cost.
Saans generates a gentle amount of extra air pressure inside the lungs during inhalation and — especially — during exhalation. You can roughly imagine this by taking a balloon and blowing it up until it's full. If you were to breathe through your nose while keeping the balloon opening in your mouth, you would start to feel pressure from the balloon building into your mouth.
Saans takes in variable pressure from a resuscitation bag or bellow and converts it into constant pressure airflow through an intuitive arrangement of pressure and flow control valves. It creates sufficient pressure during the end of the patient's exhalation phase, keeping alveoli open. The pressure isn't much — about 5 — 10 cm of water pressure is all that's necessary. In pulmonary edema, this pressure forces the excess fluid to leave the interstitial tissue surrounding the alveoli, allowing better exchange of gasses.
