WebAirway resistance is the opposition to flow caused by the forces of friction. the ratio of driving pressure to the rate of air flow. Resistance to flow in the airways depends on whether the flow is laminar or turbulent, on the dimensions of the airway, and on the viscosity of the gas. For laminar flow, resistance is quite low. WebDynamic compliance describes the compliance measured during breathing, which involves a combination of lung compliance and airway resistance. This is defined as the change in lung volume by the change in pressure, in the presence of flow. Static compliance describes pulmonary compliance when there is no airflow, like an inspiratory pause.
