In the case of chronic bronchitis, how does the body attempt to correct ventilation/perfusion mismatch?
By reducing the pressure in the pulmonary trunk
By increasing the amount of oxygen in the lungs
How does an increase in dead space affect alveolar ventilation (VA)?
no effect on alveolar ventilation since the air that doesn't participate in gas exchange still helps oxygenate the blood.
reduces alveolar ventilation since more air is ventilating areas that do not participate in gas exchange, leading to less effective oxygenation of the blood
improves alveolar ventilation because more air fills the parts of the lungs that are responsible for oxygen exchange, leading to better oxygenation of the blood.
In the case of chronic bronchitis, how does the body attempt to correct ventilation/perfusion mismatch?
How does an increase in dead space affect alveolar ventilation (VA)?
An 83 y/o patient with SEVERE chronic obstructive pulmonary disease has been experiencing increasing breathlessness over time.
How do you explain the progression of the patient’s lung volumes and capacities as the disease worsens?
What does residual volume refer to?
What is ventilation/perfusion mismatch?
