Progress in application of non-invasive ventilator in patients with chronic heart failure with sleep apnea

The incidence of sleep apnea in chronic heart failure (CHF) is >50% and severely affects the prognosis of patients with heart failure. Successful application of noninvasive mechanical ventilation to CHF patients now draws more and more attention. Different modes of noninvasive mechanical ventilation may lead to different treatment outcomes. It is important to select an appropriate mode to achieve the greatest effects.
