Patting the back can loosen the sputum attached to the alveolar wall and fall off through vibration, which is beneficial to the patient's expectoration. For patients who stay in bed for a long time, this is an effective nursing method, which can help them prevent and improve lung infection.
However, the time and frequency of back patting will also change according to the patient's specific physical condition. For example, for patients with fever, cough with yellow phlegm and shortness of breath, the nursing staff should immediately notify the doctor and carry out corresponding nursing operations according to the doctor's advice.
The above information is for reference only. If necessary, it is recommended to consult a professional medical staff.
