smoke inhalation occurs when a person breathes in hot air, smoke, or chemical fumes, which can cause burns or swelling in the air passages. life-threatening carbon monoxide poisoning can occur with smoke inhalation.
the person may be restless, confused, or violent from the smoke and toxic gases inhaled. a changed mental state may be a direct effect of the toxins or may be caused by a lack of oxygen (hypoxia).
urgent medical attention is needed for someone with symptoms of smoke inhalation. these symptoms include:
- difficulty breathing.
- noisy breathing.
- wheezing.
- hoarseness, trouble speaking, or inability to speak in full sentences.
- coughing.
- dark-coloured sputum.
- a change in mental state, such as restlessness, confusion, or sleepiness (lethargy).
