Nasal incitement, also known as nasal agitation, is a manifestation of unfavorable lung breathing, where nostril expansion and narrowing, or nasal agitation, can be seen when breathing, and is commonly seen in pediatric asthma, severe pneumonia, lobar pneumonia, heart failure, and other diseases. So patients in the treatment of nasal incitement need to be treated according to the original cause of nasal incitement, so that it can be cured as soon as possible. Diseases that cause nasal incitement: 1, acute respiratory distress syndrome (ARDS) The disease can cause respiratory distress, hypoxemia, accompanied by nasal flapping, shortness of breath, sweating, cyanosis, scattered wet and dry rales. Tachycardia, anxiety and decreased level of consciousness may also be present. 2. Airway obstruction Complete airway obstruction above the tracheal bifurcation may cause sudden nasal flapping with loss of breath sounds despite the application of intercostal contractions and significant paraspinal muscles. Tachycardia, sweating, cyanosis, decreased level of consciousness, and eventually respiratory arrest. Incomplete obstruction can lead to nasal flapping, wheezing sounds, violent cough, application of paramuscular muscles, agitation, cyanosis, and hoarseness. 3. Allergic reactions Severe reactions can cause respiratory distress, including nasal flapping, wheezing, application of paramuscular muscles, and intercostal contractions. Associated symptoms include nasal congestion, sneezing, itching, urticaria, erythema, sweating, angioedema, weakness, hoarseness, and dysphagia. Individual cases may present with nausea, vomiting, diarrhea, urinary urgency, urinary incontinence, and later cardiac arrhythmias and shock.
