icddr,b doctor rebuilt $15k ventilator as $3 shampoo-bottle CPAP
Dr. Chisti at icddr,b rebuilt a $15,000 ventilator as a $3 bubble CPAP from a shampoo bottle, cutting child pneumonia deaths in a trial.

the move
Severe childhood pneumonia is one of the leading causes of death for children in poor countries, and the standard respiratory-support device that reliably saves these children — a mechanical ventilator — costs up to $15,000. District hospitals in Bangladesh, the secondary-level facilities that see the largest volume of severe pneumonia cases, had no realistic path to owning enough ventilators at that price, so children who failed to improve on basic low-flow oxygen had no further respiratory support available and often died.
The obvious response — get more ventilators into poor hospitals — was never going to happen at a $15,000 unit cost against district-hospital budgets, and there was no cheaper commercial alternative on the market delivering the same clinical function. Dr. Mohammod Jobayer Chisti, a senior scientist at Bangladesh's icddr,b, needed a device that could deliver the same physiological effect as a ventilator's respiratory support without requiring anything close to a ventilator's price.
why it works
- Bubble CPAP's pressure comes from tube depth in water, not electronics.
- Shampoo bottle and tubing provide airtight water column at near-zero cost.
- Trial showed dramatic mortality cut, proving cheap version works.
- Low cost lets district hospitals afford and scale the device.
what transfers
When a tool is priced for rich markets, check if its core mechanism is simple physics that cheap parts can replicate.
what came after
A randomized controlled trial of 225 children with severe pneumonia and low blood oxygen, run at icddr,b and published in The Lancet in 2015, found bubble CPAP cut mortality dramatically compared with standard low-flow oxygen therapy — the trial was stopped early once the mortality difference between groups became clear. The technology has since been tested in district-hospital settings and other countries including Ethiopia and Malawi, and by 2026 Bangladesh's Ministry of Health and Family Welfare was jointly scaling it nationwide with icddr,b specifically to fight measles-related pneumonia d
