Prompt assessment , with control of airway patency and provision of ventilation if required are essential. This will help to prevent secondary hypoxic damage to the brain and other vital organs. Without adequate oxygenation it may be impossible to restore an organised , perfusing cardiac rhythm. These principles may not apply to the witnessed primary cardiac arrest in the vicinity of a defibrillator; in this case , the priority is immediate defibrillation followed by attention to the airway.  \nCauses of airway obstruction  \nObstruction of the airway may be partial or complete. It may occur at any level from the nose and mouth down to the level of the carina and bronchi. In the unconscious patient , the commonest site of airway obstruction is the pharynx. The precise cause of airway obstruction in the unconscious state has been identified by studying patients under general anaesthesia. Airway obstruction had previously been attributed to posterior displacement of the tongue caused by decreased muscle tone , with the tongue ultimately touching the posterior pharyngeal wall. These studies of anaesthetised patients have shown that the site of airway obstruction is more often at the soft palate and epiglottis and not the tongue. Obstruction may also be caused by vomit or blood , as a result of regurgitation of gastric contents or trauma , or by foreign bodies. Laryngeal obstruction may be caused by oedema from burns , inflammation or anaphylaxis. Upper airway  \nstimulation or inhalation of foreign material may cause laryngeal spasm. Obstruction of the airway below the larynx is less common , but may be caused by excessive bronchial secretions , mucosal oedema , bronchospasm , pulmonary oedema , or aspiration of gastric contents. Extrinsic compression of the airway may also occur above or below the larynx e. g. trauma , haematoma or tumour.  \nRecognition of airway obstruction  \nAirway obstruction can be subtle and is often missed by healthcare professionals. Recognition is best achieved by the look , listen and feel approach.  \n• LOOK for chest and abdominal movements.  \n• LISTEN and FEEL for airflow at the mouth and nose.  \nIn partial airway obstruction , air entry is diminished and usually noisy.  \n• Inspiratory stridor-caused by obstruction at the laryngeal level or above.  \n• Expiratory wheeze-suggests obstruction of the lower airways , which tend to collapse and obstruct during expiration.  \n• Gurgling-suggests the presence of liquid or semisolid foreign material in the upper airways.  \n• Snoring-arises when the pharynx is partially occluded by the tongue or palate.  \n• Crowing or stridor- is the sound of laryngeal spasmor obstruction.  \nComplete airway obstruction in a patient who is making respiratory efforts causes paradoxical chest and abdominal movement , described as ‘see-saw breathing’. As the patient attempts to breathe in , the chest is drawn in and the abdomen expands; the opposite occurs in expiration. This is in contrast to the normal breathing pattern of synchronous movement of the abdomen upwards and outwards (pushed down by the diaphragm) with lifting of the chest wall. During airway obstruction , accessory muscles of respiration are used-the neck and the shoulder muscles contract to assist movement of the thoracic cage. There may also be intercostal and subcostal recession and a tracheal tug.
