Text: On-demand inhalation, as compared with fixed-schedule inhalation, was associated with a significantly shorter estimated mean length of stay -- 47. 6 hours (95 % confidence interval [CI], 30. 6 to 64. 6) versus 61. 3 hours (95 % CI, 45. 4 to 77. 2 ; P = 0. 01) - as well as less use of oxygen supplementation (in 38. 3 % of infants vs. 48. 7 %, P = 0. 04), less use of ventilatory support (in 4. 0 % vs. 10. 8 %, P = 0. 01), and fewer inhalation treatments (12. 0 vs. 17. 0, P < 0. 001).
