The most relevant knowledge about oxygen administration to a patient with COPD includes:1. Oxygen at 1-2 L/min is given to maintain hypoxic stimulus for breathing2. Hypoxia stimulates the central chemoreceptors in the cortex that makes the patient breathe3. Oxygen is administered best using a non rebreathing mask4. Blood gases are monitored using a pulse oximeter

Answer» Correct Answer - Option 1 : Oxygen at 1-2 L/min is given to maintain hypoxic stimulus for breathing

CONCEPT:

  • Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs.
  • Symptoms include breathing difficulty, cough, mucus (sputum) production, and wheezing.

  • Oxygen therapy is a type of treatment used by some people with chronic obstructive pulmonary disease (COPD). It is sometimes called supplemental oxygen.

 

EXPLANATION:

  • COPD causes lung damage that can keep the lungs from being able to absorb enough oxygen. If the body does not have enough oxygen, it cannot function as well as it should.
  • Oxygen therapy delivers an extra supply of oxygen into the body that can help improve symptoms of COPD.
  • According to the studies, supplemental oxygen is used for at least 15hours/day and oxygen is delivered at a rate of 2litres/min.

Hence, the correct answer is Oxygen at 1-2 L/min is given to maintain hypoxic stimulus for breathing.
