- Environmental factors
What are some physiological factors that impact oxygenation
.....ANSWER.....- anemia
- Hypovolemia

,Page 2 of 45
What are two physiological changes that impact chest wall
movement? .....ANSWER.....- pregnancy
- obesity
What are some alterations to respiratory functions?
.....ANSWER.....- Hypoventilation
- Hyperventilation
- Hypoxia
What is the definition of hypoventilation? .....ANSWER.....- occurs
when alveolar ventilation is inadequate to meet O2 demands
- occurs when alveolar ventilation is not sufficient enough to
eliminate proper CO2 amounts
What is retained during hypoventilation? .....ANSWER.....- CO2
What does hypoventilation cause? .....ANSWER.....respiratory
acidosis
,Page 3 of 45
What is the definition of hyperventilation? .....ANSWER.....- Lung
removes CO2 faster than it is produced via cellular metabolism
What is hyperventilation caused by? .....ANSWER.....- severe
anxiety
- infection
- drugs
- acid-base imbalance
What are some signs / symptoms of hyperventilation?
.....ANSWER.....- Rapid respiration
- sighing breaths
- numbness / tingling in hands/ feet
- light headedness
- loss of consciousness
, Page 4 of 45
What is the definition of hypoxia? .....ANSWER.....- inadequate
tissue oxygenation at the cellular level.
What does hypoxia result from? .....ANSWER.....- deficiency in
O2 delivery
- deficiency of O2 utilization at a cellular level
What can cause hypoxia to occur? .....ANSWER.....- decreased
level of hemoglobin & lowered O2 carrying capacity of blood
- diminished concentration of inspired O2 at higher altitudes
- inability of tissue extraction O2 from the blood (cyanide
poisoning)
- decreased diffusion of O2 from the alveoli to the blood
(pneumonia)
- poor tissue perfusion w/ oxygenated blood
- impaired ventilation
