ReSVinet Scale*
| Item | 0 point | 1 point | 2 points | 3 points |
| Feeding intolerance | No. | Mild: decreased appetite and/or isolated vomits with cough. | Partial: frequent vomits with cough, rejected feed but able to tolerate fluids sufficiently to ensure hydration. | Total: oral intolerance or absolute rejection of oral feed, not able to guarantee adequate hydration orally. Required nasogastric and/or intravenous fluids. |
| Medical intervention | No. | Basic: nasal secretions aspiration, physical examination, trial of nebulised bronchodilators, antipyretics. | Intermediate: oxygen therapy required. Complementary examinations were needed (chest X-rays, blood gases, hematimetry, etc). Maintained nebulised therapy with bronchodilators. | High: required respiratory support with positive pressure (either non-invasive in continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP) or high-flow oxygen; or invasive through endotracheal tube). |
| Respiratory difficulty | No. | Mild: not in basal situation but does not appear severe. Wheezing only audible with stethoscope, good air entrance. If modified Wood-Downes, Wang score or any other respiratory distress score is applied, it indicates mild severity. | Moderate: makes some extra respiratory effort (intercostal and/or tracheosternal retraction). Presented expiratory wheezing audible even without stethoscope, and air entrance may be decreased in localised areas. If modified Wood-Downes, Wang score or any other respiratory distress score is applied, it indicates moderate severity. | Severe: respiratory effort is obvious. Inspiratory and expiratory wheezing and/or clearly decreased air entry. If modified Wood-Downes, Wang score or any other respiratory distress score is applied, it indicates high severity. |
| Respiratory frequency | Normal <2 months: 40–50 bpm. 2–6 months: 35–45 bpm. 6–12 months: 30–40 bpm. 12–24 months: 25–35 bpm. 24–36 months: 20–30 bpm. | Mild or occasional tachypnoea: presented episodes of tachypnoea, well tolerated, limited in time by self-resolution or response to secretion aspiration or nebulisation. | Prolonged or recurrent tachypnoea: tachypnoea persisted or recurred despite secretion aspiration and/or nebulisation with bronchodilators. | Severe alteration: severe and sustained tachypnoea. Very superficial and quick breath rate. Normal/low breath rate with obvious increased respiratory effort and/or mental status affected. Orientative rates of severe tachypnoea: <2 months: >70 bpm; 2–6 months: >60 bpm; 6–12 months: >55 bpm; 12–24 months: >50 bpm; 24–36 months: >40 bpm. |
| Apnoea | No. | Yes. At least one episode of respiratory pause medically documented or strongly suggested through anamnesis. | ||
| General condition | Normal. | Mild: not in basal situation, child was mildly uncomfortable but does not appear to be in a severe condition, not impress of severity. Parents are not alarmed. Could wait in the waiting room or even stay at home. | Moderate: patient looks ill and will need medical examination and eventually further complementary examinations and/or therapy. Parents are concerned. Cannot wait in the waiting room. | Severe: agitated, apathetic, lethargic. No need for medical training to realise severity. Parents are very concerned. Immediate medical evaluation and/or intervention were required. |
| Fever | No. | Yes, mild central temperature <38.5°C. | Yes, moderate central temperature >38.5°C. |
