V/Q mismatch ~~> Ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables = ventilation (V) and perfusion (P) Mechanical insufficiency ~~> Structural damage- Nervous System (alter resp rate and depth), Muscles (Abdo, intercoastal, diaphragm- (impact intrathoracic vol= dec pressure to exchange air), Airway obstruction- physiological and foreign objects (inflammation, obstructions) Medication- CNS Depressa...

Diffusion affected by ___ and ___ (thickness) of alveoli to capillary SURFACE AREA and DISTANCE Ventilation movement of air in and out of the lungs Ventilation (V) - exchange of alveolar air (gaseous flow rate) Perfusion Circulation of blood within an organ or tissue in adequate amounts to meet current needs of the cells. Perfusion (Q) - pulmonary circulation (blood flow rate; quantité = French quantity or amount) V/Q mismatch An imbalance in the amount of oxygen received in the alveoli an...
