Inspection: pediatrics

·       Flared nostrils

·       Capillary refill greater than 2 seconds (super important in peds)

·       Retracts in ribs (skin looks like it is caving into each rib as they breath)

·       Pale skin

·       Frightened look

 

 

Palpation: chest rise

·       Thoracic expansion

·       Have pt take deep breath in and out and your fingers should move 5-10 cm symmetrically

o   Decrease in movement would mean:

§  Pneumonia

§  Collapsed lung

 

Palpate the anterior and posterior chest wall

·       Tenderness

o   Chest wall, musculoskeletal strain

·       Crepitus

o   When air is pushed through the soft tissue chest

o   Popping under skin

o   Looking for pneumothorax (collapsed lung)

·       Decreased fremitus

o   Excess air in lungs (COPD)

o   Thickness of chest wall

·       Excess fremitus

o   Lung consolidation

§  Inflammatory exacerbate

o   Pneumonia

Percussion

·       Tone—resonance

o   Borders for cardiac dullness

·       Hyperresonance: emphysema, pneumothorax

o   Air trapping (excess air)

o   Higher pitched

o   Expected to hear:

§  Bone

§  Liver

o   Either fluid mucus puss, or lump mass or tumor

·       Symptoms: dyspnea, tachypnea, chest pain, dry cough, cyanosis, asymmetric lung expansion, tracheal shift to unaffected side (large tension pneumo), decreased or absent tactile fremitus, hyperresonance (rare), diminished or absent breath sounds, no adventitious sounds

 

Atelectasis

·       Collapsed alveoli caused by external pressure

·       Risk Factors

o   Anesthesia, foreign object in airway (kids), lung diseases, mucus plug, pleural effusion, prolonged bedrest, shallow breathing (i.e. pain), tumors

·       Symptoms: Cough, dyspnea/tachypnea, tachycardia, cyanosis, O2 sats may decrease <90%, possible tracheal shift to affected side, decreased chest expansion on affected side, decreased or absent tactile fremitus, dullness, Affected lobe has diminished or absent breath sounds

 

Pulmonary malignancies

o   Uncontrolled growth of anaplastic cells in lung

·       Risk Factors:

o   Cigarette smoking is major cause (85%)

·       Clinical Manifestations:

·       Most common initial symptom is a persistent cough

·       Asymptomatic (10-25%)

·       Weight loss, congestion, wheezing, labored breathing, or dyspnea, hemoptysis

·       Percussion may be normal or may be dull over the tumor or with atelectasis

 

Older adult considerations

·       Tenderness or pain at the costochondral junction of the ribs is seen with fractures, especially in older clients with osteoporosis.

·       Older adults may experience dyspnea with certain activities related to aging changes of the lungs (loss of elasticity, fewer functional capillaries, and loss of lung resiliency).

·       Chest pain related to pleuritis may be absent in older clients because of age-related alterations in pain perception.

·       The ability to cough effectively may be decreased in the older client because of weaker muscles and increased rigidity of the thoracic wall.

·       Deep breathing may be especially difficult for the older client, who may fatigue easily. Thus offer rest as needed.

·       Kyphosis (an increased curve of the thoracic spine) is common in older adults.

·       Because of calcification of the costal cartilages and loss of the accessory musculature, the older client’s thoracic expansion may be decreased, although it should still be symmetric.

·       The sternum and ribs may be more prominent in the older client because of loss of subcutaneous fat.
