WebThe diffusion gradient across the membrane is reduced (i.e., reduced P 1 −P 2). This can occur if perfusion is too low. Identifying whether deranged blood gases are due to diffusion or perfusion limitations can help in the diagnosis of an underlying pathological issue, so we will look at them here. Diffusion Versus Perfusion Limitations WebGas diffusion involves random molecular movement from areas of high partial pressure to areas of low partial pressure. The rate of diffusion depends on the partial pressure (or tension) difference between each area. The partial pressure (P) of a gas in a mixture is the pressure that a given gas would exert if it alone occupied the space.Partial pressures are …
