Free AMLS Oxygen Therapy Question and Answers — Questions and Answers
Question 1: Which device is typically used for delivering low-flow oxygen therapy?
- Ventilator
- Nasal cannula (Correct answer)
- CPAP machine
- Nebulizer
Correct answer: Nasal cannula
A nasal cannula is the most commonly used device for delivering low-flow oxygen therapy, typically at flow rates between 1 and 6 liters per minute. It consists of two prongs that fit comfortably into the nostrils, providing supplemental oxygen without obstructing the patient's ability to eat, drink, or speak. Other devices like ventilators or CPAP machines deliver higher pressures or volumes, while nebulizers deliver medication.
Question 2: Which of the following is a potential side effect of long-term oxygen therapy?
- Hypercapnia (increased CO2 levels) (Correct answer)
- Hypothermia
- Weight gain
- Muscle cramps
Correct answer: Hypercapnia (increased CO2 levels)
In patients with chronic obstructive pulmonary disease (COPD) who have chronic hypercapnia, long-term oxygen therapy can sometimes suppress the hypoxic drive to breathe. This can lead to decreased ventilation and an increase in carbon dioxide (CO2) levels in the blood, resulting in hypercapnia. Careful monitoring of blood gas levels is essential to prevent this complication.
