Is your shortness of breath precipitated on exertion? Or does it persist throughout the day? Do you have cough during shortness of breath? If so is it associated with expectoration ( production of sputum)? Dyspnoea( shortness of breath) can be due to both cardiac or pulmonary origin. Since you are already taking Furosemide which is a diuretic that reduces the volume load on your heart, I assume that you have been diagnosed with heart failure. In that case, if furosemide alone with dose escalation does not suffice to control your symptoms, you need to be put on a combination therapy depending on the stage of your heart failure. Also be advised that albuterol is a bronchodilator which serves to reduce shortness of breath due to bronchial asthma. It will have no effect if you are suffering from heart failure associated shortness of breath. Have you had an echocardiography done? It will help in quantifying your heart failure. Also get a digital X-ray of your chest (AP and Lateral views) to exclude any lung pathology. Equipped with these reports you can consult a cardiologist who shall grade your heart failure and start you on an appropriate combinational drug therapy
