Obstructive Lung Disease Flashcards
Patient with Obstructive Pulmonary Disease will have difficulty inhaling or exhaling?
Exhaling
What are the 2 most common S/S of Obstructive Lung Disease?
Dyspnea upon exertion and a productive cough
What is the 3rd most deadliest disease?
COPD
What are the 2 primary causes of Obstructive Lung Disease
Inhalation(smoking)
Genetics(affects surfactant and integrity of alveolar sac).. inherited a1-antitrypsin deficiency
T/F: All persons, smoking or non, will experiences a decrease in FEV1?
True
T/F a patient with COPD who quits smoking can experience a FEV1 decline that parallels a non-smoking, age matched person
True
Place the following terms in order based off the process of obstructive airway diseases:
- obstruction
- irritant
- inflammation
- infection
- elastic recoil destroyed
Irritant->inhalation leads to airway and alveolar inflammatory response, continues as long as irritant is present, long exposure will cause irreversible damage
Infection->speeds process
Inflammation->starts in small airways of lungs, breaks down elastin and connective tisssue, leads to hyperplasia and mucus secretion
Obstruction->hypersecretion of mucus, mucus plugging, edema, increased reactivity and eventual bronchial fibrosis and destruction of terminal airways
Elastic recoil destroyed
Obstructive lung disease will cause lung hypoinflation or hyperinflation?
Hyperinflation
What is the gold standard of hyperinflation of the lungs and its gas exchanging capabilities?
ABG
Decreased bucket handle action at the ribs would indicate _____ angled ribs ____degrees
- horizontal or vertical
- <90 degrees or >90 degrees
horizontal ribs >90 degrees
Elevation of the shoulder girdle that occurs with lung hyperinflation is caused by?
Accessory muscles being used for ventilation instead of the diaphragm
During hyperinflation the diaphragm will take on what shape?
Low, flattened shape
Common s/s of lung hyperinflation include:
elevation of the shoulder girdle
horizontal ribs
barrel shaped thorax
low flattened diaphragm
Name that dyfunction:
Expiration: mucous plugs and narrowed airways cause air trapping and hyperinflation on expiration, decreased elastic recoil of bronchial walls results in collapse of airways and prevents normal expiatory airflow
Inspiration: airways pulled open, allowing gas to flow past the obstruction
COPD
What posture does a COPD patient take on?
Forward leaning posture
COPD patients would have cyanosis or flushin?
Cynosis and clubbing
COPD patients would have increased or decreased breath sounds and increased or decreased CO2?
Decreased breath sounds, increased CO2, decreased O2
What long volumes(2) and ratio would prominently be affected by COPD?
FEV1, FVC, FEV1/FVC ratio
How could a flatted diaphragm from lung hyperinflation cause pelvic and/or bladder issues
Increased pressure causes incontinence
Muscle composition for COPD patients would change to what type of fiber?
Type II fast twitch
How many stages of COPD are there?
4
Chronic respiratory failure is considered anything less than what percent of the FEV1/FEVC?
50%
The stages of COPD look at what ratio to define respiratory failure and what lung volume?
FEV1/FVC
FEV1/FVC must be less than what to be considered mild, moderate or severe?
The degree of severity of COPD is dependent of FEV1/FVC or the lung volume FEV1?
FEV1
