QuestionAnswer
If the radius of a respiratory airway is decreased by 2, then the flow would be decreased by a factor of ___.
In an restrictive disorder, the FEV1/FVC ratio is ____ (higher or lower) than normal.
patients have chronic cough with sputum production. Have severe inflammation with airway obstruction. Severe Hypoxemia and Hypercapnea
sympathetic agonist used to treat asthma
Preemies born before ____ weeks have collapsed alveoli due to no lung surfactant and high lung recoil.
Main resistor of the lungs
Type of flow with a reynolds number > 4000
type of asthma that is induced by allergens
Stage of inspiration characterized by a decrease in pleural pressure but no change in lung volume
Reduction in surfactant causes a ____ in lung recoil.
What is the pressure (cm H20) required to open an alveolus during tidal volume breathing?
______ diseases are characterized by the inability to deflate the lungs. They include emphysema, asthma and COPD
Surfactant creates a ____:air interface which reduces surface tension.
Premature babies born before 28 weeks present with ____ due to a lack of surfactant.
T/F: As the lungs deflate, airway resistance is increased exponentially due to a decrease in the radii of the airways.
If the length of airway decreases, what would happen to the flow of air? (increases or decreases)
normal percentage of a FEV1/FVC ratio
the amount of air that can be forcefully exhaled within one second
According to LaPlaces Law, an increase in airway/ alveolar radius causes a ____ ( increase or decrease) in the pressure required to hold it open.
If the viscosity of air increases, what would happen to the flow of air? (increases or decreases)
T/F: It is easier to open a closed airway than to hold it open.
In absence of surfactant, what would happen to lung compliance?
T/F: There is a very high resistance to flow in the alveoli
major site of airway resistance
Type of flow with a reynolds number between 2000 -4000
More surfactant causes a _____ in lung compliance.
In an obstructive disorder, the FEV1/FVC ratio is ____ (higher or lower) than normal.
Surfactant decreases the air:water surface tension by a factor of about ___.
An increase in the pressure gradient would ____ air flow.
patients have a reddish complexion. They hyperventilate, and are usually thin with pursed lips. Experience some hypoxemia but do not become hypercapnic
QuestionAnswer
Stage of inspiration characterized by a decrease in pleural pressure and an increase in lung volume
T/F: Work on expiration only occurs in pathological processes.
According to LaPlaces Law, an increase in surface tension causes a ____ ( increase or decrease) in the pressure required to hold it open.
The air:water surface tension contributes what percentage to lung recoil properties?
In an obstructive disorder, the FEV1 value is ____ (higher or lower) than normal.
Which variable of Poisuelle's Law influences resistance the most?
T/F: The elasticity of the lungs is influenced by elasticity of the lung tissue and surface tension of the air:water interface.
______ (restrictive or destructive) disorders are characterized by a decrease in total lung capacity.
type of asthma that is exercise or cold induced
the difference in the pressure volume curves for inspiration and expiration is known a _____.
Stage of inspiration that is marked by an increase in the transpulmonary pressure gradient that has diminishing returns due a decrease in lung comliance
Type of flow with a reynolds number < 2000
As we move toward a lower lung volume, airway resistance will _____ (increase or decrease) exponentially.
The flow of air in the lungs stops when the lungs reach the _____ volume, where resistance is very high.
_____ adrenergic receptors can be found on the bronchi, causing bronchodilation.
______ (restrictive or destructive) disorders are characterized by a increase in residual volume.
T/F: Both obstructive and restrictive disorders have a decrease in vital capacity.
Which pneumocytes produce surfactant?
T/F: In the pulmonary system, the sympathetic nervous system causes bronchoconstriction through epi and noreepinephrine, whil parasympathetic causes bronchodilation through ACH.
What anatomical feature of the segmental bronchi contributes to the high resistance?
The elasticity of lung tissue contributes what percentage of lung recoil properties?
T/F: Reduction in surface tension, reduces the amount of pressure required to keep an alveolus open.
______ diseases are characterized by the inability to properly inflate the lungs. They include pulmonary fibrosis and edema.
