What is positive expiratory pressure therapy? Can it improve the cough and shortness of breath after Yang Kang?

PEP (positive expiratory pressure therapy) loosens viscous secretions through the vibration of airflow, generates positive pressure through the resistance during exhalation, then supports the airway and pushes the loosened secretions upward to the upper part of trachea, which is beneficial to cough up viscous sputum. Inhale and hold your breath, then exhale, and the valve closes to form positive pressure; The resistance can be adjusted to meet the needs of different patients.

At present, many patients with Yang Kang will have cough, shortness of breath, chest tightness and other problems, which are more common. This is because COVID-19's physical function has not fully recovered after his rehabilitation. Especially for people with fragile respiratory tract. At this time, positive expiratory pressure therapy can be used for breathing training. First of all, we can increase vital capacity and improve airway ventilation. Instead, vibration can be used to eliminate phlegm and dredge airway secretions.

However, it should be noted that positive expiratory pressure therapy needs equipment assistance. For example, you can use a laughter breathing trainer. The advantages are simple operation, convenient cleaning and disinfection, and can be used by both the elderly and children. ?
