High frequency chest wall oscillation expectoration machine

Work principles The Chest Expectoration Machine repeatedly and gently taps the patient's chest through high-frequency oscillating airflow, causing the viscous secretions in the respiratory tract to resonate, fall off, and gather, stimulating the patient to cough and achieve the effect of phlegm discharge. Whole Chest Oscillating Expectoration Machine removes secretions and sputum caused by pneumonia, bronchial diseases, etc., relieves bronchial smooth muscle spasm, eliminates edema, and reduces obstruction. Whole Chest Oscillating Expectoration Machine increases blood oxygen concentration, promotes smooth breathing, and enhances patient comfort.
