sternum and posterior: between the scapula
Bronchial: Loud, high-pitched sounds (heard mainly over the manubrium).
Abnormal/Adventitious Breath Sounds
Crackles: is a discontinuous bubbling, crackling sounds heard over lung fields, common in
pneumonias, CHF.
Wheezes is a musical sounds produced by narrowed bronchial airways; common in COPD &
Asthma.
Friction Rubs: are grating sounds over surface of thorax; indicates inflammation of pleura.
The Older Adult and Respiratory Function
↓ elastic recoil of lungs during expiration d/t less elastic collagen
Alveoli are less elastic
Loss of skeletal muscle strength in the thorax and diaphragm
Aging and disease affect the respiratory function and airway clearance
The number of cilia decreases
Cough weakens
Diminished cough and gag reflexes
At increased risk of dehydration, which can lead to thick, viscous mucus that is difficult to
expectorate
Immune function also declines with age (↑ risk of pulmonary infection and ability to fight the
infection processes)
Immobility, smoking history, surgery, malnutrition, polypharmacy and existing lung disease
(COPD) also increase risk for respiratory infections.
PNEUMONIA (acute inflammation of the lungs
- Inflammatory disease of the lung with either (collection of pus (empyema), fluid (pleural effusion), or
consolidation within the pleural space.
Caused by different infectious agents (bacteria, virus, fungal) and by inhalation of chemicals or
aspiration of gastric content.
Types of Pneumonia include:
