,NSG 252 EXAM


-Hypoxia


What is hypoventilation? ANS >> Occurs when alveolar ventilation is inadequate
to meet the oxygen demand of the body or eliminate sufficient carbon dioxide


What is hyperventilation? ANS >> A state of ventilation in which the lungs
remove carbon dioxide faster than it is produced by cellular metabolism


What is hypoxia? ANS >> Inadequate tissue oxygenation at the cellular level


Cardiac alterations ANS >> -Disturbances in conduction
-Altered cardiac output
Left and right sided heart failure
-Impaired valvular failure
-Myocardial ischemia
Angina and myocardial infarction


Lifestyle factors affecting oxygenation ANS >> Nutrition
Hydration
Exercise
Smoking
Substance abuse
Stress
