What is the primary goal of oxygen therapy in patients with chronic obstructive pulmonary disease (COPD)?
A) To decrease carbon dioxide levels
B) To increase oxygen saturation
C) To improve exercise tolerance
D) To reduce respiratory rate
When comparing the amount of oxygen gas to the amount of other gasses in air or our bodies, we use the term..
1.) Partial pressure
2.) Gas pressure
3.) Oxygen gradient
4.) Oxygen availability
5.) Gas concentration
Explain the procedure for administering oxygen therapy to patients.
