Respiratory failure, one of the most common conditions we treat, can be caused by many conditions such as asthma, emphysema, chronic obstructive pulmonary disease (COPD), complications of surgery, lung weakness created by an overdose of narcotics or sleeping pills, premature birth, or injuries in trauma. The condition may also result from extensive burns, muscular disease, neurological disease, profuse bleeding, drowning, heart failure, severe infection and/or extreme obesity. Often, a patient may need mechanical ventilation to help with breathing during respiratory failure.
