<s>[INST] I have had two patients a week apart both suffer from asthma attacks. The first one was foaming at the mouth. The foam was clear, like spit bubbles. Both patients stopped breathing for some time and rescue breaths were given. After about 6-10 rescue breaths, both patients began shallow breathing on their own. Is this normal? [/INST] Hello, These are serious symptoms, and you need to ensure that both of them do not suffer from allergies that may have triggered the symptoms. The attack that you describe is sort of something like airway obstruction with saliva as the foam and ensure that they have an anaphylaxis management plan in place. If this was after a food they had ingested, a food allergy definitely needs excluding. Happy to elaborate if you have further issues. Thanks. </s>
