Cardiogenic croup is caused by heart failure, so the treatment is to give oxygen, change to sitting position, legs down, reassure the patient, medication for heart failure, medication for airway hyperresponsiveness, airway spasm, and if the patient’s condition is critical need to give life-supporting equipment, emergency resuscitation. Cardiogenic asthma is caused by acute left heart failure, mainly related to pulmonary stasis edema, treatment focus is mainly divided into the following aspects; 1. patients are given oxygen to improve hypoxia, if the effect of nasal catheter oxygen is poor can apply high flow oxygen or non-invasive ventilator oxygen. 2. The patient’s position is changed to sitting or semirecumbent position, with both lower limbs hanging down, to reduce the amount of return blood, and must pay attention to pacify the patient, if agitation is obvious, you can properly apply sedative drugs, such as diazepam. 3. For heart failure to give diuretic, dilation, cardiac, heart rate control and other drugs, such as furosemide, digoxin, nitroglycerin, etc., the acute phase of the preferred choice of intravenous drug. Patients with airway spasm can be applied to improve airway spasm, anti-inflammatory drugs, such as aminophylline, ipratropium bromide, budesonide and so on. 4. If the patient’s condition is critical, it is necessary to give life support equipment, such as invasive ventilator ventilation, aortic balloon counterpulsation to correct heart failure. Patients with cardiogenic asthma are usually in a more acute condition and should be treated in the hospital as soon as possible.
