Parameter, Sex, Age (years), Height (cm), Ethnic group, Measured value.
Requires technically acceptable spirometry. The ethnic-group adjustment materially changes the result; choose it correctly.
Oxygenation Index for severity stratification of paediatric ARDS (PARDS).
Severity assessment of an acute paediatric asthma exacerbation from respiratory rate plus four clinical signs (5–15).
Three-item bedside score (0–6) for grading acute asthma severity in children from wheezing, work of breathing, and prolonged expiration.
Grades croup severity from five clinical signs (0–17) to guide treatment and disposition.
Difference between alveolar and arterial oxygen tension — assesses the cause of hypoxaemia (gas-exchange defect vs hypoventilation).
Non-invasive oxygenation severity index (uses SpO₂ instead of PaO₂) for grading pediatric ARDS (PALICC).
