COPD/Asthma Flashcards
Leading cause of chronic obstructive pulmonary disease?
Smoking
COPD physiology?
Alveoli collapse, mucus inside bronchioles, smaller airway. Air trapped into lungs. Inhalation is easier and exhalation is harder and takes longer
What happens during an asthma attack?
The bronchioles become enflamed, causing bronchospasm and increased mucous that results in: coughing, wheezing, and SOB.
Asthma Irritants?
Pollen, exercise, food, cigarette smoke, dust mites, pollution
Signs/symptoms of asthma?
Chest tightness, shortness of breath, wheezing, cough, anxiety.
What does a nebulizer do?
Produces a continuous flow of aerosolized medication that can be taken in during multiple breaths, over several minutes giving the patient a greater exposure.
What are some side effects from a prescribed inhaler?
Increased pulse rate, tremors, nervousness.
Common bronchodilator
Albuterol. When aerosolized, it causes the bronchioles/bronchi to expand allowing more room for airflow into the lungs.
Flow rate for a nebulizer?
6-8 lpm
Two common conditions that contribute to COPD?
Chronic bronchitis and emphysema
“Pink puffer” refers to a patient with what condition?
Emphysema
“Blue bloater” refers to a patient with what condition?
