QUESTIONS AND ANSWERS
Define obstructive sleep apnea. ANSWER - -Tongue and the soft palate fall backward
- Partial/complete obstruction of the pharynx
- Obstructs for 10-90 seconds
- Causes hypoxemia and hypercapnia
What are the risk factors for sleep apnea?. ANSWER - Snore, tired, obstruction,
pressure, BMI, age, neck, and gender.
What are the risk factors associated with sleep apnea?. ANSWER - - Cardiovascular
events (MI, CVA, HTN, and dysrhythmias)

Explain the mandibular advancement device. ANSWER - Forces the lower jaw
forward.
Explain continuous positive airway pressure therapy. ANSWER - - Splints airway
open
- Compliance is often poor, needs to be worn every night
Define COPD. ANSWER - - Progressive airflow obstruction
- Ongoing dyspnea, decreased activity tolerance, and increased mucous/coughing
Explain the pathophysiology of COPD. ANSWER - - Chronic inflammation causes
airway constriction
, - Airflow and ventilation decrease
- Work of breathing and diminished respiratory drive often cause hypoventilation
and retention of CO2
- Function of alveolar macrophages increases susceptibility of infection
How do the alveoli change with COPD?. ANSWER - - The alveoli become
permanently enlarged and the alveolar walls are destroyed
- This results in impaired gas exchange
What are the risk factors of COPD?. ANSWER - - Smoking
- Age
- Occupation
- Previous respiratory diseases
What are the clinical manifestations of COPD?. ANSWER - - Congested cough
- Dyspnea and use of accessory muscles
- Low oxygen
- Increased RR
- Wheezing, decreased air entry, and crackles
What are the signs and symptoms of COPD?. ANSWER - - Lack of energy
- Unable to tolerate activity
- Nutrition is poor
- Gases
What tools are used to diagnose COPD?. ANSWER - - Pulmonary function test
- Physical assessment
- Medical history
- Arterial blood gas
