I need to know how these situations influence ventilation?
1) increased respiratory passageway resistance
2) decreased lung compliance
3) lack of surfactant
Airflow = (difference in pressure between the alveoli and the atmosphere) / resistance. Therefore, if the resistance increases, the airflow decreases. It's that simple. That means that it's harder for the air to pass through the passageways.
Lung compliance refers to the capacity of the lungs and the thoracic cavity to expand. When compliance is high, the expansion occurs easily; when it is low, expansion occurs with great difficulty. That means that the ...
