The annual global incidence of pneumonia is 9 to 0000 new cases per year out of which 282000 occurring in South Asia , though, there is evidence of decreased mortality and decreased need for invasive ventilation after use of CPAP in managing units with respiratory distress, secondary to RDS , MAS and apnoea of prematurity in NICU. There is only limited evidence for use of CPAP in infants and children with respiratory conditions like pneumonia, ARDS, pulmonary edema and status asthmaticus with very few observational and randomised control studies, indicating that CPAP exhibits promising potential in enhancing ventilation and oxygenation among infants, with pneumonia with respiratory distress and use of CPAP, may mitigate the need for endotracheal, intubation and potentially need to shorter duration of PICU stays for the young patients . Among different CPAP devices, bubble CPAP demonstrate the specific advantage of cost effectiveness, ease of assembling and its operability with any available oxygen source gives it an upper hand in low and middle income countries. Nevertheless, there is minimal evidence of CPAP efficacy in pneumonia. This study aims to investigate low-cost bubble CPAP, safety and effectiveness in paediatric respiratory distress. As a result of pneumonia, filling a critical knowledge gap in paediatric respiratory care to minimise mortality and morbidity .
