How should one vomit?
A. Every medical book that has an opinion says that the head should be kept lower than the hips while vomiting. This is to prevent aspiration of the vomit into the lungs. This is especially important while holding a small child who may not know what to do. In practical terms, this means that one should stand upright and bend over so that the mouth is almost in the toilet. Children should be taught to vomit this way. Anecdotal evidence suggests that most people disregard this advice and either kneel or squat in front of the toilet, positions which do nothing to protect one’s airway. Despite the common sense of it, it makes no difference in terms of efficiency what position the body is in.
