September 2017: Recommendation 1.4.3 was corrected to properly divide 2 bullet points. Table 3 and recommendations 1.4.9 and 1.9.2 were corrected to give oxygen saturation as less than 92% in air. Table 2 was amended to include tympanic temperature as a moderate risk factor. Table 3 was amended to add pallor of skin, lips or tongue as an intermediate to high risk factor, and recommendation 1.4.9 was amended to remove pale or flushed as an intermediate risk factor. Minor corrections for consistency have been made between the recommendations, tables and algorithms. The accompanying algorithms have been redesigned to help with readability.
July 2016: The accompanying algorithms and risk tables have had some some minor typographical errors corrected, and reference to systolic blood pressure levels wrongly included in some algorithms for children have been removed.
