3. status of a sinus infection
4. elasticity of the lung tissue
5. pulse oximeter reading of 97%

Lung compliance is the distensibility of the lungs. It depends on the elasticity of the lung tissue and the flexibility of the rib cage. Patency of the nares, a sinus infection, or pulse oximeter readings do not affect lung compliance.
