Respiratory Viruses in Acute Bronchiolitis in Delhi.

We studied the etiology of bronchiolitis in Delhi. Respiratory syncytial virus (RSV) was the most commonly isolated virus in 72/245 infants (30%). RSV positive cases did not have more severe disease; this argues against routine use of ribavirin.

A simple circuit to deliver bubbling CPAP.

Nasal continuous positive airway pressure (CPAP), especially bubbling CPAP, is known to reduce the need for more invasive ventilation. We here describe a circuit that can deliver bubbling CPAP in resource poor settings. We describe how the oxygen concentration can be altered from 98% to 21% oxygen using this system. Addition of a humidifier in the circuit has the effect of reducing the oxygen concentration by 1 to 5%. The cost of putting together the system is approximately Rs 5000.
