Table 4 : Score of Respiratory Severity: This score was modelled after the score of respiratory severity published by C. Marguet and adapted to the present study [1]. Markers of respiratory severity Duration of hospital stay Oxygen dependancy ICU hospitalization Initial saturation in room air Clinical score of respiratory severity ≤ 5 days no no > 92% 0 > Score ≤ 6 > 5 days yes yes ≤ 92% Score > 6 Clinical score of respiratory severity SCORE I : Flaring of the nostrils Thoraco-abdominal dissynergia Intercostal recession Sternal recession none visible 0 1 0 1 0 1 0 1 Total score = ……… (0 – 8) important 2 2 2 2 SCORE II : Wheezing 0 none 1 During expiratory phase Relation of inspiratory and expiratory duration Reactivity I > E (inspiratory stridor) normal I=E Nutrition Normal tired 2 During expiratory and inspiratory phase, or diminished breath sounds I < E (grunting) No reaction or poor general condition Nasogastric tube Parenteral nutrition Total score = …….. (0-8) SCORE III : SCORE I + SCORE II = ...... (0 – 16) Respiratory disease was severe if the score was > 6.
