   Normal people can pass Airway Cilia epithelial cells, the immune system and repeated irritation of the cough expectoration. However, due to excessive and sticky mucus, old age, poor health, chest pain, and disturbance of consciousness, the body may experience difficulty in expelling phlegm, reflex Bronchospasm, disorder of mucus secretion, and difficulty in clearing away phlegm, easy to occur atelectasis, pneumonia, Pulmonary Edema, leading to respiratory dysfunction and lung infection complications. Clearing Sputum in time is the primary nursing measure to ensure the airway unobstructed, and it is also an effective method to prevent lung infection. A large number of sputum did not expel in time, forming sputum scab attached to the tracheal wall, resulting in obstruction of respiratory tract ventilation, resulting in decreased lung ventilation function and aspiration dysfunction. The main aim of Airway nursing is to establish and keep airway unobstructed, maintain proper alveolar function, oxygen and gas exchange function, and expectoration is the most basic and routine nursing intervention in airway nursing.

EXPECTORANT VS. expectorant

   Currently there are a variety of airway purification methods, which can be roughly divided into two categories according to their principles: one is to act on the cough and respiratory link, moving secretions from the distal airway to the proximal one to expel sputum, the main methods are catheter stimulation and tracheal compression, mechanical cough (MI-E technique) , acupoint percussion, and the other is to loosen and expel sputum by causing vibration of the thorax or vibration of inhaled gas, the main methods are postural drainage, percussion and expectoration.

   There are some problems in the application of various airway purification methods commonly used in clinical practice in China. For example, manual vibration of the lung and expectoration means that the patient inhales deeply enough gas to expand the lung tissue, and the operator presses the patient's chest or upper abdomen to help increase the peak flow rate of cough (PCF) , need nursing staff to accurately judge the location of sputum in the lung, assessment of sputum in the lung, the operation is difficult, the safety is not easy to control. On the basis of the traditional buckle back, through the choice of the amplitude and time of the instrument, the handle is attached to the patient's chest or back, which causes the sputum to vibrate and makes the sputum move to the airway, if the amplitude of this method is not appropriate, it will lead to sputum accumulation, prone to Hypoxia, spasticity and other complications, and can only clear a small part of the airway.

   To sum up, a safe and effective method of airway clearance is needed in clinic.

The Philips expectorant MI-E technology is such a safe and efficient method. The principle is to imitate the normal physiological state of the cough action, in inspiration to provide positive pressure ventilation filling the Alveoli, expand the Bronchi; in the air to quickly switch to negative pressure, produces A high-speed air stream that directs the sputum to the OROPHARYNX and out of the body. MI-E can be used in cases of insufficient removal of sputum due to respiratory weakness or loss of consciousness, as an alternative to tracheal suction to reduce mucosal damage, increase patient comfort, and expand the lungs to prevent atelectasis, is a full range of clinical needs to meet the airway cleaning treatment options.
