The process that exchanges gases between the external environment and the alveoli is called:
If a patient vomits and aspirates their stomach contents where in their lungs is it most likely to end up?
Right middle and lower lobes
How do pleural pressures vary when moving from the base of the lung to the apex of the lung?
They decrease as they move up the lungs
What is the average alveolar pressure throughout the respiratory cycle?
0 cm H20
When is pressure in the alveoli the highest?
Beginning of expiration
Lung compliance is:
The ease of lung distention
What is normal compliance for the respiratory system of a spontaneously breathing patient?
100 mL/cm H20
What does Hooke's Law discuss?
Force and stretch are directly related within the physiologic limits
What role does surfactant play within the lungs?
Stabilizes the alveoli, particularly the small ones
If the volume breathed into the lung is 300 mL, and the pressure required to move this air in is 10 cm H20, what is the lung compliance?
30 mL/cm H2O
Based on Hooke's Law, if we apply too much pressure or volume to the lung what is likely to happen?
Your 25 yo female who is breathing 14 b/min and has a PaCO2 of 51 mm Hg. She can be said to be:
Given the respiratory rate 16 and tidal volume of 500 mL, what is the Minute Ventilation?
Given that the change in pressure is 8 cm H2O and the flow .5 L/s, what is the airway resistance?
How would you characterize the airway resistance you just computed?
What will explain a patient that has a significantly increased minute volume, but no change in PaCO2?
Of all the factors that affect the required driving pressure, which factor has the greatest effect? (defined by Poiseuille's Law)
Kussmaul's breathing is best described as:
rapid deep breathing
Cheyne- Stokes breathing is best described as:
waxing and waning of respirations followed by periods of apnea
Which of the following might be caused by a deficiency of surfactant in the lung?
