Abstract: Medical devices and techniques derive breath rate, breath distention, and pulse distention measurements of a subject from a pulse oximeter system coupled to the 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 application for animal research.

Abstract: An electro-impedance tomography (EIT) system (2), with a computing unit (4) and a respirator (1) is described for gentle mechanical lung ventilation especially in case of atelectases. The presence, the extent and/or the spatial distribution of atelectases is detected by the EIT system (2) and sent to the respirator (1) so that the respiration pressure is increased step by step by the respirator (1) until the current image of the lung status corresponds to a first status image of healthy lungs or comes close to it with minimal deviations. The respiration pressure is subsequently reduced again step by step by the respirator (1) until the computing unit (4) detects a reduction of the ventilated lung areas and the respiration pressure is subsequently increased again by means of the respirator (1) to the last value at which no change occurred in the ventilated lung areas.

Abstract: A process is provided for monitoring a patient being anesthetized, as well as a process for determining a combined effect of different anesthetics used. Devices for carrying out the processes are also provided.

Abstract: An integrated tail mounted blood pressure monitor and pulse oximeter system includes a tail blood flow occlusion member configured to selectively occlude blood flow through the tail; a sensor coupled to the tail blood flow occlusion member detecting a degree of operation thereof; Light sources coupled to the tail closer to the distal end of the tail than the tail blood flow occlusion member, and selectively directing light of two different wavelengths into the tail; a light receiver coupled to the tail and selectively receiving a signal associated with light directed into the tail from the light sources; and a controller configured to selectively determine blood pressure parameters from the data and pulse oximeter parameters from the data.
