QuestionAnswer
Volume of air than can be inhaled at the end of a normal breath
patients with emphysema have a ____ lung compliance
pressure in the atmosphere is ___ cm h20
Work during breath occurs on ____.
Z number or generation number for the trachea
Volume of air that can be exhaled after normal expiration (=total lung capacity - residual volume)
Normal Tidal Volume in liters
Which component of Fick's Law can be manipulated in the clincial setting?
2 main forces that must be overcome during breathing?
pressure difference between the alveoli and the pleural space is known as ____ ____.
T/F: Gas exchange ocurrs in the conducting airways.
Volume of air that can be exhaled as forcibly and rapidly as possible from total lung capacity
Volume of air remaining in the lungs after a normal expiration
Volume of air in lungs after maximal inspiration
T/F: The terminal bronchioles are surrounded by smooth muscle
Total volume of air in lungs after maximal inspiration
Has Z numbers spanning from Z17-Z23
T/F: During inspiration, the pressure in the alveolus become sub-atmospheric, allowing air from the atmosphere to move into the lungs.
low partial pressure of oxygen in tissues
Volume of air in lungs remaining after maximal expiration
Where is the majority of the surface area of the lung located?
T/F: During inspiration, the transpleural pressure difference becomes greater and allows for expansion of the lungs and alveoli.
Lung recoils is used during ____.
On average, how much time does an RBC spend in the respiratory airways (sec)?
Volume of air in the respiratory or alveolar airways (mL)
Average Lung Compliance for a tidal volume in L/cm H20 (Avg Volume = .5 and change in Pressure= 2.5)
Is the airflow in the respiratory or alveolar airways laminar or turbulent?
low partial pressure of oxygen in blood
patients with pulmonary fibrosis have a ___ lung recoil
QuestionAnswer
Function of these airways is to clean, condition, and warm air
Maximal volume of air that can be inhaled after normal expiration (=tidal volume +IRV)
T/F: A 'diffusion limited' A-a gradient is smaller than under normal circumstances.
Essential muscle in creating differences in transpleural pressure
Principal(or Law) that provides the basis for airflow in the lung
Gas moves across the alveoli via _____ diffusion
T/F: An increase in particle size increases rate of diffusion
most important muscle for inspiration
given change in lung volume per given changes in pleural pressure
Which gas is the first to be affected by a diffusion limited disorder?
Is the airflow in the conducting airways laminar or turbulent?
units for measurement of transpulmonary pressure
True or False: The rate of diffusion is proportional to the area of the membrane and inversely proportional to it thickness
T/F:An Increase in molecule solubility increases rate of diffusion
As the diaphragm contracts. the volume increases in the pleural space. What happens to the pleural pressure?
Volume of exhaled air with every breath is known as ____ volume.
These bronchi are the site of highest resistance to airflow and are surrounded by smooth muscle
pressure in the pleural cavity is normally ____ cm H2O at the end of a tidal volume breath
If the transpulmonary pressure is +3, then the lungs are ____ (collapsing or expanding).
inversely proportional to lung compliance
Volume of air in the conducting airways (mL)
site of gas exchange in the lung
Has a Z number that spans from Z0-Z16
The diaphragm, the external intercostals, and the sternocleidomastoids are important for _____.
Volume of air in lungs after maximal expiration
A ____ in surface area and a _____in membrane thickness can cause the lung to become diffusion limited.
Maximal Volume that can be exhaled at the end of a tidal volume
The internal intercostals and the abdominal muscle are important for ____.
