The device can help patients expel phlegm more easily, reduce the risk of respiratory infections, and improve lung function. The process of using the Oscillating Expectoration Machine is usually to fix the vibrating device on the patient's chest, and then control the vibration frequency and intensity of the device to achieve the discharge of sputum. Patients can undergo sputum treatment regularly according to the doctor's advice. Whole Chest Oscillating Expectoration Machine is suitable for various respiratory diseases, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, etc. It can help improve patients' breathing, redu…
