Question:
PFTs Evaluating
Answer:
lung volumes or the ability to fully expand flow rates, rate of inflow and outflow of air maximal voluntary ventilation or airflow through the major airways by completing rapid inspiration expiration maneuvers evaluation of diffusing capacity or the ability of the oxygen to get into the blood
Question:
PFTs Measures
Answer:
Spirometry evaluates the amount of air exhaled and inhaled during forced maneuvers Lung volume refers to the total amount of air in the lungs with maximal inspiration.diffusing capacity measures gas exchange and is often done in conjunction with a pulse oximetry reading.
Question:
Normal PFTs
Answer:
FEV1 (80% to 120%), FVC (80% to 120%), Absolute FEV1/FVC Ratio (Within 5% of the predicted ratio), TLC 2 / 3
(80% to 120%), FRC (75% to 120%), RV (75% to 120%), DLCO (>60% to <120%),
Question:
Restrictive Lung Disease=
Answer:
decrease in the total volume of air that the lungs can hold. decrease in the elasticity, inability of the chest wall to expand during inhalation
Question:
associated with restrictive lung function
Answer:
interstitial lung disease such as idiopathic pulmonary fibrosis, sarcoidosis, obesity, including obesity hypoventilation syndrome, scoliosis, neuromuscular diseases such as muscular dystrophy or amateur amyotrophic lateral sclerosis (ALS) associated
