Abstract: Apparatuses are described to accurately determine a gas concentration of a sample of a patient's breath. The apparatuses may include a sample compartment, a breath speed analyzer, a gas analyzer, and a processor. The sample compartment includes an inlet that receives the breath. The breath speed analyzer determines the speed of a portion of the breath. The gas analyzer determines a gas concentration. The processor includes an algorithm that determines a degree of non-homogeneity of the sample based on the speed, and a corrected gas concentration based on the degree of non-homogeneity. In some variations, the gas correction is determined independently of patient cooperation. Apparatuses may be tuned based on the intended population's expected breathing pattern ranges such that the sample compartment is filled with a homogenous end-tidal gas sample regardless of an individual's breathing pattern. These apparatuses are useful, for example, for end-tidal CO analysis. Methods are also described.

Abstract: Methods and systems are described to obtain and analyze one or more gas samples from the breath of a person, and organizing the samples in a sample registry for subsequent analysis. This technique solves the various problems that are associated with targeting an individual breath for analysis, and allows for additional versatility and options in the analysis process.

Abstract: A breath parameter measuring device is described which takes into account breathing patterns which historically have been incompatible with accurate measurements. In particular, during fast breathing patterns, the sensor performing the measurement may not be able to respond quickly enough to provide the true reading. The disclosure may be useful for example in the case of neonatal breath carbon dioxide measurements.

Abstract: Methods for administering immune globulin and devices for use thereof. The methods may generally include measuring a patient's hemolysis levels and determining whether the patient is suitable for immune globulin treatment, determining whether immune globulin treatment should be continued, and/or determining if the dose needs to be changed.

Abstract: Methods and systems are described to obtain and analyze a gas sample from a desired section of the breath of a person, while accounting for erratic, episodic or otherwise challenging breathing patterns that may otherwise make the capturing of a gas sample from the desired section of breath difficult. These techniques may provide more reliable, accurate and adequate samples of gas such as end-tidal gas, and ultimately an accurate analysis of the sample captured.

Abstract: Methods and systems are described to automatically obtain and analyze a lung airway gas sample from the breath of a person for compositional analysis. These techniques may provide an improved method for example for accurately and reliably measuring nitric oxide for asthma assessment in young children and non-cognizant patients.

Abstract: Breath analysis systems and methods test for infectious diseases in exhaled breath gas or condensate. An automatic breath sampling system can obtain reliable samples over a variety of clinical situations. In some variations, the system is modular system and can protect the equipment and clinician from contamination. In some variations, the system can be a point-of-care rapid-result instrument. In some variations, can be configured for off-line analysis in which case the collected sample is presented to a stand-alone analyzer for measurement.

Abstract: A breath analysis device is described which obtains a desired segment of one or more breaths, and analyzes that or those samples for compositional analysis. A pneumatic control system may obtain these segments homogeneously, may reduce the amount of gases included from other segments of the breath, and may reduce mixing with other segments once obtained. These pneumatic control systems can be used for on-board compositional analysis, or for modular or off-board compositional analysis.
