When performing pulmonary function tests on a child, which of the following would the best data for determining flow rates
FEV0.5
What is the normal value for residual volume
1200ml
Emphysema mostly affects these tiny, elastic "air balloons" inside the lungs where gas exchange happens
Alveoli
What is the normal value for Total Lung Capacity (TLC)
5000ml
Cough during the 1st second most directly affects interpretation of
FEV1
What is the normal value for FRC
2400ml
This common respiratory condition—often called a "chest cold"—involves short-term inflammation of the lung's bronchial tubes and typically triggers a persistent, mucus-producing cough
Bronchitis
Before an exercise test, you suspect the treadmill displays 3.0mph when it is actually slower. What is the recommended verification method
Belt length X revolutions/time
Measure belt travel over a known distance/time (tape and marker method) and adjust the controller
A flattened inspiratory limb suggest possible
Extrathoracic Obstruction
What law states that that the pressure of a given mass of gas is inversely proportional to it's volume when the temperature is constant
Boyles Law
What disease checks for an abnormally high amount of salt (chloride) in a newborn's sweat.
Cystic Fibrosis
Your DLCO shows erratic CO readings after switching to humidified inspirate. What is the best fix to stabilize the analyzer response
Install Nafion Tubing
A flattened expiratory limb suggests possible
Intrathoracic Obstruction
A DLCO maneuver requires at least ___% of volumes and a breath hold time of ___seconds
90% & 10 seconds
A pulmonologist is most likely to treat this chronic condition where the lungs' airways become abnormally widened, leading to a buildup of excess mucus.
Bronchiectasis
Daily spirometer verification is performed using a 3L syringe with a single patient filter. Flow yield 2.92L, 2.96L, and 3.08L. Do you accept this verification?
YES
FRCpleth values 3.36, 3.16, 3.37. Do these trials meet ATS criteria?
YES
What is the minimum volume required (VIN%) required for quality grade of A when FVC is 2.5L?
2.25L
This condition has a myth that claims that people with well-controlled asthma should completely avoid physical exertion
Asthma
Before a water seal spirometer is used, the most appropriate way to check for a leak
place a weight on the bell and check the pen movement for 5 minutes
