Which pair correctly identifies a type of compliance included in the calculations?

• A. Static and dynamic
• B. Elastic and vascular
• C. Rheological and kinetic
• D. Cubic and linear

Answer: (A)

Compliance is about how easily the respiratory system expands in response to pressure. In routine ventilation calculations, two forms are used: static compliance, measured when there is no gas flow and using plateau pressure minus PEEP, which reflects the elastic properties of the lung and chest wall; and dynamic compliance, measured during active flow using peak inspiratory pressure minus PEEP, which reflects both elastic properties and airway resistance. These two together are the types of compliance included in the calculations. The other pairings don’t fit this context: elastic and vascular aren’t the standard calculation categories for respiratory compliance; rheological and kinetic aren’t used in this setting; cubic and linear describe relationships rather than specific compliance types.
