DPAP provides effective bi-level positive airway pressure treatment for a variety of respiratory conditions including Obstructive Sleep Apnea (OSA).
        
       A Bi-level device is ideal for the treatment of tubercular and non-tubercular lung diseases. There are significant numbers of Chronic Obstructive Pulmonary Disease (COPD) cases that require basic ventilation support. In such cases, Bi-level support without the complications of invasive ventilation proves to be very effective. Bi-level can also be effective in case of Acute Respiratory Distress Syndrome (ARDS) and asthma
