What are 4 signs of a serious chest injury?

Signs and symptoms of chest injury include:.
pain in the chest that gets worse when laughing, coughing or sneezing..
pain when breathing in..
difficulty breathing..
tenderness to the chest or back over the ribs..
bruising..
swelling..
a 'crunchy' or 'crackling' feeling under the skin or in the ribs..
coughing up blood..

What are the most common signs and symptoms of a patient with chest trauma with respiratory distress?

Respiratory distress is a serious problem in individuals with blunt chest trauma. Patients with respiratory distress may breathe with nasal flaring, using accessory muscles, intercostal and subcostal retractions, and signs such as tachypnea. The patient's lungs may not be equally involved in breathing.

Which type of chest trauma produces a dull sound on percussion of the affected side?

At the same time, hemothorax can cause atelectasis in the lungs and cause respiratory distress. Flattening of the neck veins, hypotension, tachycardia, decreased breathing sound, dullness in the percussion examination of the injured area should suggest hemothorax.

Which finding indicates that a patient has a flail chest?

The strict requirement for a diagnosis of flail chest—at least three ribs close together broken in two or more places—can be confirmed only by taking an x-ray. But all other significant symptoms can be observed through a simple physical exam.
