Boussignac CPAP is effective in the majority of patients with cardiac asthma (=acute cardiogenic pulmonary edema). This therapy is given in addition to the furosemide,morphine and nitroglycerine. The duration of the treatment with Boussignac CPAP is 2h at most.

What is cardiac asthma

Cardiac asthma is also called acute left decompensation or acute cardiogenic pulmonary edema. The incidence of cardiac asthma is rising, mainly because the number of patients with chronic heart failure is increasing. Cardiac asthma typically presents itself with sudden severe dyspnea which is caused by the accumulation of fluid in the lungs.
When the heart fails (for example because of myocardial ischemia, cardiomyopathy, rhythm disturbances or valvular disease) the pumping action of the heart is impaired. Frequently this results in a stagnation of blood, which also affects the lungs. This in turn causes pulmonary edema with increased fluid in the alveoli.
In some patients, cardiac asthma is most manifest during the night. The recumbent position combined with gravity favors the accumulation of fluid in the lungs during heart failure. Thus the patient can awake with acute dyspnea.
