Rate sensitivity of blood pressure to hypoxia

A biochemical kinetic model is used to describe changes in mean arterial blood pressure in dogs to three different rates of fall of arterial partial pressure of oxygen. The model is a linear loop with one variable rate coefficient (parametric control) which has been previously shown to characterize the rate sensitivity to presented stimuli. A three component model was identified under a least squares criterion and it showed that a unique (stimulation independent) representation can be obtained which can serve as a conceptual framework for the study of this phenomenon.
