Abstract
Medical devices and techniques derive breath rate, breath distention, and pulse distention measurements of a subject from a pulse oximeter system coupled to a subject. These parameters, together with the conventional physiologic parameters obtained from a pulse oximeter system, can be used to assist in controlling the ventilation levels and the anesthesia levels of the subject. The development has human applications and particular applications for animal research.
