見急救達人quote咗UK guideline，就回應下
首先，講講下St John個ADULT basic life support指引教戴口罩就spin咗去講PEDIATRIC BLS recommendation，大家頭腦一唔清就好易俾呢種論述帶走。
同埋人地UK個guideline係講緊pediatric abnormal breathing, impeding to full cardiac arrest時要立即俾rescue breath以避免惡化至full cardiac arrest。當你兒童完全無pulse嘅cardiac arrest時都係要CPR，唔可以淨俾氧氣。
留意返如果係兒童嘅話，俾氧氣個marginal benefit大過成人好多，而現時嘅paediatric BLS guideline cardiac arrest時都係30:2 or 15:2 depending on availability of help，無叫你戴口罩。（兒童hands only CPR not recommended but is acceptable, any CPR is better than no CPR）
Btw，人地個UK adult BLS guideline都係叫你放個cloth/towel, consistent with AHA同St John嘅guideline，唔好quote d唔quote d玩埋d偷換概念。
#講成人走咗去講兒童
#人地兒童BLS都無改做戴口罩
