Study Notes

Breathing Terminology

Apnea: Complete absence of breathing.
Atelectasis: Collapse of a lung segment affecting gas exchange.
Biot's respirations: Characterized by rapid, deep breaths followed by short periods of apnea.
Bradypnea: Abnormally slow breathing, less than 12 breaths per minute.
Cheyne-Stokes respirations: A pattern of gradual increase in breathing rate and depth, followed by a decrease, with possible pauses of 10 to 20 seconds.
Dyspnea: Labored or painful breathing, indicating respiratory distress.
Hemoptysis: Coughing up blood-stained mucus.
Hyperventilation: Rapid and deep breathing beyond normal levels.
Hypoventilation: Slow, shallow, or irregular breathing patterns.
Hypoxemia: Insufficient oxygen levels in the blood.
Hypoxia: Inadequate oxygenation of tissues at the cellular level.
Kussmaul respirations: Extremely deep and rapid breathing often associated with metabolic acidosis.
Orthopnea: Difficulty in breathing when lying flat, often relieved by sitting up.
Orthopneic position: Position involving sitting up and leaning forward for ease of breathing.
Oxygen concentration: Measures the portion of hemoglobin that is bound to oxygen, critical for assessing respiratory efficiency.
Pollutant: Harmful substances present in air or water, impacting respiratory function and overall health.
Respiratory arrest: A critical condition where breathing ceases completely.
Respiratory depression: A reduction in breathing rate and effectiveness, with fewer than 12 breaths per minute.
Sputum: Mucus that is expelled from the respiratory tract, often analyzed for diagnostic purposes.
Tachypnea: Rapid breathing, exceeding 20 breaths per minute.

Factors Influencing Oxygen Needs

Physiological Factors:
- Functionality of the respiratory and circulatory systems
- Red blood cell count impacts oxygen transport
- Nervous system status affects respiratory drive
Environmental & Lifestyle Factors:
- Aging can lead to decreased lung capacity and oxygenation
- Exercise increases oxygen demand due to elevated metabolic activity
- Fever raises metabolic rate, heightening oxygen requirements
- Pain can restrict breathing patterns, affecting oxygen intake
- Substance use (drugs, alcohol) can depress respiratory function
- Smoking and exposure to pollutants compromise lung function
- Nutritional status influences overall health and oxygen requirements
- Allergies may exacerbate respiratory conditions and oxygen needs

Recommended Breathing Positions

Easier Breathing Positions: Fowler's or semi-Fowler's, which encourage optimal lung expansion and ease of breathing.
