Table 1. ReSVinet scale.
This table presents the original scale, and was the one used by the three investigators.
| Item | 0 points | 1 points | 2 points | 3 points | |
|---|---|---|---|---|---|
| 1 | 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 |
| 2 | Medical intervention | No | Basic Nasal secretions aspiration, physical examination, trial of nebulized bronchodilators, antipyretics. | Intermediate Oxygen therapy required. Complementary exams were needed (chest X-rays, blood gases, hematimetry…). Maintained nebulized therapy with bronchodilators. | High Required respiratory support with positive pressure (either non-invasive in CPAP, BiPAP or high-flow O2; or invasive through endotracheal tube). |
| 3 | 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 localized 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. |
| 4 | Respiratory frequency | Normal < 2 m: 40–50 bpm 2–6 m: 35–45 bpm 6-12m: 30–40 bpm 12-24m:25–35 bpm 24-36m: 20–30 bpm | Mild or occasional tachypnea Presented episodes of tachypnea, well tolerated, limited in time by self-resolution or response to secretion aspiration or nebulization. | Prolonged or recurrent tachypnea Tachypnea persisted or recurred despite secretion aspiration and/or nebulization with bronchodilators. | Severe alteration Severe and sustained tachypnea. Very superficial and quick breath rate. Normal/low breath rate with obvious increased respiratory effort and/or mental status affected. Orientative rates of severe tachypnea: < 2 m: > 70 bpm 2–6 m: > 60 bpm 6-12m: >55 bpm 12-24m: >50 bpm 24-36m: >40 bpm |
| 5 | Apnea | No | Yes At least one episode of respiratory pause medically documented or strongly suggested through anamnesis. | ||
| 6 | 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 exam and eventually further complementary exams and/or therapy. Parents are concerned. Cannot wait in the waiting room. | Severe Agitated, apathetic, lethargic. No need of medical training to realize severity. Parents are very concerned. Immediate medical evaluation and/or intervention were required. |
| 7 | Fever | No | Yes, mild Central T < 38.5°C | Yes, moderate Central T > 38.5°C |
