Abstract: An apparatus for analyzing the composition of bodily fluid. The apparatus comprises a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient; and a pump unit in operative engagement with the fluid handling network. The pump unit has an infusion mode in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus further comprises a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample. In one implementation, the pump unit comprises a first pump operable in the infusion mode but not in the sample draw mode, and a second pump operable in the sample draw mode but not in the infusion mode.

In other embodiments, optical and/or electrochemical analysis can be performed simultaneously on multiple components of a fluid sample. In some embodiments, a first analyte can be measured in a sample (e.g., whole blood) before the sample is separated into its components (e.g., plasma, red blood cells, etc.), and a second analyte can be measured in a component of the sample after separation.

Abstract: The volume of fluid removed from a patient during ultrafiltration is controlled automatically on the basis of central venous pressure (CVP) measurements. In one embodiment, a central venous catheter (CVC) is used for accessing blood during dialysis. A sensor located at the tip of the catheter or inside the dialysis machine is used to periodically measure CVP. CVP feedback data helps prevent the excessive removal of fluids from the patient.

Abstract: A method and infrared sensing device for determining the concentration of alveolar alcohol in a breath sample exhaled by a subject into an infrared sensing device. The presence of alcohol from the upper respiratory tract of the subject is detected by continuously monitoring alcohol and carbon dioxide, normalizing alcohol values with respect to carbon dioxide, calculating a difference between normalized alcohol concentration and carbon dioxide concentration over time, integrating (summing) the difference, and comparing the integrated difference with a threshold. This technique accurately and consistently detects the presence of mouth alcohol in the sample before the presence of carbon dioxide which originates in deep lung breath.

Abstract: A method determines an analyte concentration in a sample including the analyte and a substance. The method includes providing an absorption spectrum of the sample. The absorption spectrum has an absorption baseline. The method further includes shifting the absorption spectrum so that the absorption baseline approximately equals a selected absorption value in a selected absorption wavelength range. The method further includes subtracting a substance contribution from the absorption spectrum. Thus, the method provides a corrected absorption spectrum substantially free of a contribution from the substance.
