With a barrel chest, the normal elliptical configuration of the chest is replaced by a rounded one in which the anteroposterior diameter enlarges to approximate the transverse diameter. The diaphragm is depressed and the sternum is pushed forward with the ribs attached in a horizontal, not angular, fashion. As a result, the chest appears continuously in the inspiratory position. (See Recognizing barrel chest.)

Typically a late sign of chronic obstructive pulmonary disease (COPD), barrel chest results from augmented lung volumes due to chronic airflow obstruction. The patient may not notice it because it develops gradually.

Recognizing barrel chest
For a normal adult chest, the ratio of anteroposterior to transverse (or lateral) diameter is 1:2. For a patient with a barrel chest, the ratio approaches 1:1 as the anteroposterior diameter enlarges.

HISTORY:
Ask the patient about a history of pulmonary disease. Note chronic exposure to environmental irritants such as asbestos.
Ask the patient if he smokes. If so, find out how much.
Ask the patient if he has a cough. Is it productive or nonproductive? If it's productive, have him describe the sputum color, amount, and consistency.
Ask the patient if he experiences shortness of breath. Is it related to the activity?

PHYSICAL ASSESSMENT:
Observe the patient's general appearance. Look for central cyanosis in the cheeks, nose, and mucosa inside the lips. Also, look for peripheral cyanosis in the nail beds. Note clubbing, a late sign of COPD.
Observe the patient for accessory muscle use, intercostal retractions, and tachypnea.
Auscultate for abnormal breath sounds, such as crackles and wheezes.
Percuss the chest; hyper resonant sounds indicate trapped air, whereas dull or flat sounds indicate mucus buildup.
SPECIAL CONSIDERATIONS:
To ease breathing, have the patient sit and lean forward, resting his hands on his knees to support the upper torso (tripod position).

PEDIATRIC POINTERS:
In infants, the ratio of anteroposterior to transverse diameter normally approximates 1:1. As the child grows, this ratio gradually changes, reaching 1:2 by ages 5 and 6.
Cystic fibrosis and chronic asthma may cause a barrel chest in a child.

AGING ISSUES:
In elderly patients, senile kyphosis of the thoracic spine may be mistaken for barrel chest. However, unlike barrel chest, patients with senile kyphosis lack signs of pulmonary disease.

PATIENT COUNSELING:
Advise the patient to avoid bronchial irritants, especially smoking, which may exacerbate COPD. Tell him to report purulent sputum production. Instruct him to space his activities to help minimize exertional dyspnea.
