Occurs when bloodflow to the myocardium and from the coronary arteries is insufficient but damage is reversible.
Myocardial ischemia
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 primary alterations that affect ventilation
hyperventilation
hypoventilation
hypoxia
State of ventilation in excess that is required ro eliminate CO2 produced.
Hyperventilation
Causes of Hyperventilation
anxiety
infections
drugs
acid-base imbalances
Hyperventilation can be caused by an excess of these 2 drugs
salicylate
amphetamines
Occurs when alveolar ventilation is inadequate to meet the body's oxygen demand or eliminate sufficient carbon dioxide
hypoventilation
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
S/S of hypoventilation
mental status changes
dysrhythmias
potential cardiac arrest
Inadequate tissue oxygenation at the cellular level
Hypoxia
S/S of hypoxia
apprehension
restlessness
inability to concentrate
dizziness
behavioral changes
Hypoxia causes changes in which 2 vital signs?
increased HR
increases rate and depth of respiration
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
Risk factors for respiratory diseases in school-aged children and adolescents
