A patient with heart failure who has a severe cough is evidence of an exacerbation of heart failure, when severe pulmonary stasis occurs. The patient may have a violent cough and cough with pink foamy sputum. The patient should be placed in the correct position, with the patient in a sitting position and with the legs down, and given oxygen, which should be administered continuously throughout, with the oxygen concentration and flow rate adjusted according to the results of the blood gas analysis. Patients should have rapid intravenous access and be treated with cardiopulmonary drugs, such as cetiran, diuretics such as hydrochlorothiazide or furosemide, and methylprednisolone and methylprednisolone for asthma and cough in severe coughs. In addition, aminophylline can also be given to play the role of pacifying and calming asthma, and to relieve bronchospasm, while patients are given heart rate, blood pressure, pulse rate, arterial oxygen saturation and other parameters monitoring.
