1. Occurs when bloodflow to the myocardium and from the coronary arteries is insufficient but damage is reversible.
    Myocardial ischemia
  2. Transient imbalance between myocardial oxygen supply and demand.
    Results in chest pain, possible radiating into both arms, jaw, neck, and/or back.
    Last 1-15 minutes
    Angina pectoris
  3. 3 primary alterations that affect ventilation
    • hyperventilation
    • hypoventilation
    • hypoxia
  4. State of ventilation in excess that is required ro eliminate CO2 produced.
  5. Causes of Hyperventilation
    • anxiety
    • infections
    • drugs
    • acid-base imbalances
  6. Hyperventilation can be caused by an excess of these 2 drugs
    • salicylate
    • amphetamines
  7. Occurs when alveolar ventilation is inadequate to meet the body's oxygen demand or eliminate sufficient carbon dioxide
  8. Who should you be especially careful of when administering oxyen to and why?
    COPD patients.. Adapted to high CO2 levels and CO2 chemoreceptors are no longer sensitive
  9. S/S of hypoventilation
    • mental status changes
    • dysrhythmias
    • potential cardiac arrest
  10. Inadequate tissue oxygenation at the cellular level
  11. S/S of hypoxia
    • apprehension
    • restlessness
    • inability to concentrate
    • dizziness
    • behavioral changes
  12. Hypoxia causes changes in which 2 vital signs?
    • increased HR
    • increases rate and depth of respiration
  13. Risk factors for URI in infants and toddlers.
    • Exposure to other children and secondhand smoke
    • Teething process causes congestion which encourages bacterial growth and increased risk
  14. Risk factors for respiratory diseases in school-aged children and adolescents
    • secondhand smoke
    • cigarette smoking
