Therefore, there is an urgent and unmet need to develop objective, reliable and quick measures for respiratory paediatric assessment. Computerised adventitious respiratory sounds (ARS) have shown to be objective and reliable to assess/monitor respiratory diseases; however its application in children with LRTI is unknown.

Abstract Dyspnoea associated with respiratory infection is a common symptom in infancy and early childhood. Inspiratory stridor is the main symptom in cases of croup and expiratory wheezing in cases of bronchiolitis, obstructive bronchitis and acute asthma exacerbations. Dyspnoea associated with respiratory infection is a common cause of emergency department visits and unplanned hospital admissions among infants and preschool children. The assessment of dyspnea associated with acute childhood respiratory infection is largely subjective, and evidence regarding the severity of acute dyspnoea is

Treatment of lower respiratory tract infection (pneumonia and pleural infection) relies on the use of empirical broad spectrum antibiotics, primarily because reliable pathogen identification occurs infrequently. Another consequence of poor rates of pathogen identification is that our understanding of the microbiology of these infections is incomplete.

Humans are subject to infection with a wide range of commensal and pathogenic organisms.
