Question

Which of the following statements is correct? More than 1 answer may be correct.

a) Cilia continue to work effectively in people with late-stage COPD

b) The only cause of COPD is smoking

c) People with COPD tend to develop chronic O₂ retention

d) Arterial blood was immediately drawn to analyze the levels of O₂, CO₂, and pH

Answer 1

B. The only cause is smoking

COPD is chronic obstructive pulmonary Disease Is severe chronic disease.

The most common cause is smoking because the lungs are subjected to chronic irritation to inhaled substance as a result,the lung tissues become inflamed. Undernormal circumstances, the body tissues repair itself, but in case of smoking chronic repeated exposure to the irritants prevents healing and results chronic inflammation over time, permanent damage occurs.

The walls of the delicate alveoli lose their elasticity and become permanently distended like balloon they are inflated too many times. The walls also of the alveoli erode and thicken and as a result function less effectively. They began to trap air rather than allowing it to escape during expiration which decreases the amount of oxygen rich air that Can be inhaled in each breath

Cilia in air way normally move debris upward to be coughed Out,but in COPD cilia becomes clogged with tar and lose their effectiveness.

In COPD hypercapnia takes place chronic retention of CO2 ( carbon dioxide). The person may begin urge to hypoxic drive. Oxygen levels are too low and carbon dioxide levels are too high requires supplemental oxygen. Too much oxygen can , actually urge to breathe Leading to respiratory arrest.

Arterial blood Gas analyse the levels of oxygen ,carbon dioxide and pH.
