• Spirometry reference values (GLI)

  FEV1, FVC, FEV1/FVC, FEF25–75 and FEF75: predicted, LLN and z-score according to GLI-2012 and GLI global 2022

• PRAM score (asthma)

  Pediatric Respiratory Assessment Measure: severity of an acute asthma exacerbation, 0–12 points

• Westley Croup Score

  Severity of a croup episode: consciousness, cyanosis, stridor, air entry, retractions, 0–17 points

• Bronchodilator Response (reversibility)

  Change in FEV1 and FVC after bronchodilation – ERS/ATS 2022 (> 10 % of predicted) and ATS/ERS 2005 (≥ 12 % and ≥ 200 ml)

• Pediatric Asthma Score (PAS)

  Respiratory rate, oxygen requirement, auscultation, retractions, dyspnea – 5–15 points (Kelly 2000)

• Pediatric Asthma Severity Score (PASS)

  Wheezing, work of breathing, prolonged expiration – 0–2 points each (Gorelick 2004)

• Respiratory Score for Asthma

  Respiratory rate, retractions, dyspnea, auscultation – 1–12 points (Seattle Children's Asthma Pathway)

• Asthma Predictive Index (API)

  Major and minor criteria in young children with recurrent wheezing – prediction of asthma at school age (Castro-Rodríguez 2000)

• Modified Asthma Predictive Index (mAPI)

  ≥ 4 wheezing episodes plus major/minor criteria including aeroallergen and food sensitization (Guilbert 2004)

• RDAI – Respiratory Distress Assessment Instrument

  Wheezing (expiration, inspiration, distribution) and retractions (supraclavicular, intercostal, subcostal) – 0–17 points

• Wang Bronchiolitis Score

  Respiratory rate, wheezing, retractions, general condition – 0–3 points each (Wang 1992)

• Oxygenation Index (OI)

  FiO₂ × mean airway pressure × 100 ÷ PaO₂ – PARDS severity according to PALICC-2 and PALICC 2015

• Oxygen Saturation Index (OSI)

  FiO₂ × mean airway pressure × 100 ÷ SpO₂ – non-invasive alternative to the OI (SpO₂ ≤ 97 %)

• PaO₂/FiO₂ ratio

  Horowitz index with PARDS criteria for children on noninvasive ventilation (PALICC-2)

• SpO₂/FiO₂ Ratio

  Pulse oximetry surrogate for the PaO₂/FiO₂ ratio (SpO₂ ≤ 97 %) with PARDS criteria

• Alveolar-arterial O₂ gradient

  PAO₂ − PaO₂ from FiO₂, barometric pressure, PaCO₂ and PaO₂ – with age-dependent expected value
