Causes of Apnea

Introduction: Apnea

There are many causes of apnea. These include airway obstruction in the upper or lower airway. A nasal blockage can cause an airway obstruction in newborn babies, because they are generally nose breathers. Loss of muscular tone with decreased consciousness may cause upper airway obstruction as the posterior tongue displaces into the oropharynx.

Other causes of upper airway obstruction include sleep apnea, strangulation, vocal cord spasm and having edema or blood, mucus, vomit or other substances in the airway. Diseases that cause severe inflammation in the throat, such as epiglottitis or croup can also cause airway obstruction, leading to apnea.

Lower airway obstruction followed by apnea may also occur from aspiration, bronchospasm, pneumonia, pulmonary edema and drowning.

Apnea can also result from a decreased or absence of respiratory effort due to diseases disorders or conditions that affect the nervous system, which controls breathing. These include drug overdose, carbon monoxide poisoning, cyanide poisoning, stroke and severe head trauma. Other neurological causes include spinal cord injury and neuromuscular diseases, such as myasthenia gravis, poliomyelitis and Guillain-Barré syndrome.

Apnea can also result from apnea of prematurity. Apnea can also be due to severe cases of pneumothorax, asthma, COPD, pulmonary embolism, drowning, and pulmonary edema. Apnea can also result from a serious anaphylactic reaction that leads to anaphylactic shock.

In addition to the respiratory system, apnea can occur as a symptom of diseases, disorders and conditions of other body systems. For example, in the cardiovascular system, apnea can be a symptom of end-stage congestive heart failure or a severe heart attack.

Apnea can accompany end-stage shock. Apnea can also be due to a variety of traumatic causes, such as chest trauma that results in a collapsed lung or hemopneumothorax.
