Flail chest

Apnea

Bluish discoloration of the skin due to an increase in reduces hemoglobin in the blood. the condition is directly related to poor perfusion.
Cyanosis
Retractions of the tissues of the neck due to airway obstruction or dyspnea.
Tracheal tugging
A decrease in the amount of oxygen and an increase in the amount of carbon dioxide as a result of some interference with respiration.
Asphyxia
Dyspnea while lying supine.
Orthopnea
