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