Pulse oximetry is helpful in assessing the severity of hypoxemia. Because of the risk of apnoea small infants and those with severe disease should be attached to oxygen saturation and respiratory monitors. Antibiotics bronchodilators and steroids are of no value. The precise role of the nebulised antiviral agent ribavirin is unclear and its use should be reserved for children with pre-existing lung disease those with impaired immunity and infants with congenital heart disease. Mechanical ventilation is required in 2 of infants admitted to hospital either because of recurrent apnoea exhaustion or hypercapnia and hypoxaemia secondary to severe small airways obstruction. All intubated infants must have continuous Sao2 and CO2 monitoring. Naso-pharyngeal CPAP may be sufficient ventilatory support for some infants. Most children recover from the acute infection within two weeks. However as many as half will have recurrent episodes of cough and wheeze over the next 3-5 years. Rarely there is severe permanent damage to the airways bronchiolitis obliterans .
