DESCRIPTION

A therapy known as Bubble CPAP (continuous positive airway pressure) is a simple and affordable way to deliver effective respiratory treatment for children who suffer from life-threatening respiratory illnesses, but when the nasal interface responsible for delivering life-sustaining oxygen therapy does not fit, the therapy is compromised. Without an effective nasal seal, children with severe pneumonia are not getting the pressurized gas delivery they need, leading to longer hospitalizations, wasted resources and increased mortality from pneumonia. AdaptAir is the missing link in delivering effective care to dying children in the developing world.

Clinical Trials instructions regarding therapy

ICDDR,B HOSPITAL - ICU CLINICAL TRIAL

Nurses admit a new baby and randomizeto treatment arm

Dr. Chisti shows a chest X-RAY to the mother

David Janka and Dr. Shahunja make sure AdaptAir isused properly on the first baby: Hiridoi.

Hiridoi - 23 months

Monirul - 7 months

Sobor - 14 months

Getting Valuable Feedback from Doctors

Dr. Chisti with Ale Palandjoglou discussing the CAD3D model

Dr. Hasan looking closely

Dr. James underscores the importance of reusability

David shows AdaptAir to ICDDR,B doctors.

Curious ICDDR,Bdoctors got handson the prototypesright away

Getting Valuable Feedback from Nurses and Mothers

Nurses at LAMB Hospital immediately recognized how it was used

Mothers were not afraid to put AdaptAir on their noses

Nurse at ICDDR,B talking about the importance of keeping a good seal

MATLAB

Ale and David explained the benefits of Bubble CPAP at MATLAB

Finding local materials / suppliers for the straps

About 10 meters away from the front gate of LAMB Hospital wefound a supplier with elastic straps

Walked 40 meters and found a tailor who manufactured one head-strap for us

Ale sketching some straps for the tailor
