Answer

Symptoms of lower respiratory tract injury include the following:

  • Tachypnea

  • Dyspnea

  • Cough

  • Decreased breath sounds

  • Wheezing

  • Rales

  • Rhonchi

  • Retractions

Cyanosis may be present. However, cyanosis is an unreliable indicator of hypoxia because neither carbon monoxide nor CN cause cyanosis.
