Respiratory Sounds and Oxygenation Issues

Adventitious Breath Sounds

• Abnormal lung sounds occur from air movement through moisture, mucus, or narrowed airways.
• Sudden opening of collapsed alveoli can also produce these sounds.
• Bronchial breath sounds: High-pitched, harsh sounds heard over the larynx and trachea; longer on expiration than inspiration.
• Bronchovesicular breath sounds: Moderate blowing sounds over the mainstem bronchus; inspiration equals expiration.

Signs of Oxygenation Issues

• Cyanosis: Bluish or grayish discoloration of skin due to inadequate oxygenation; assessed differently for light and dark skin tones.
• Diaphoresis: Excessive sweating with moist skin surface.
• Ecchymosis: Subcutaneous blood collection causing purplish discoloration.

Edema

• Defined as excess fluid in tissues, leading to swelling with taut, shiny skin.
• Pitting edema: Indentation remains after palpation; graded based on severity.
• Causes of edema include overhydration, heart failure, kidney failure, trauma, or peripheral vascular disease.

Jaundice

• Yellow skin due to elevated bilirubin levels; indicates liver or gallbladder disease.
• Typically begins in the sclera of the eyes before affecting the skin.
• Harder to detect in darker skin; examine sclera, oral mucous membranes, palms, and soles for yellowish discoloration.

Pallor and Petechiae

• Pallor: Skin paleness from decreased blood or hemoglobin; visible in lips, nail beds, and mucous membranes.
• Petechiae: Small hemorrhagic spots indicating capillary bleeding; assess location, color, and size.

Types of Health Assessments

• Comprehensive health assessment: Broad, includes full health history and physical assessment; provides baseline data.
• Emergency health assessment: Rapid, focused assessment during critical situations; prioritizes airway, breathing, circulation.
• Follow-up assessment: Conducted regularly to monitor health changes and effectiveness of interventions.
