A system for providing a visual summary of a condition of a patient when traumatic brain injury (TBI) is suspected or diagnosed includes at least one patient condition sensor configured to sense data representative of a patient condition parameter of interest for a TBI patient; at least one airflow sensor configured to sense data representative of ventilations provided to the patient; at least one visual display for providing the visual summary to a user; and at least one controller. The at least one controller is configured to cause the visual display to provide the visual summary. The visual summary can include at least one visual representation of at least one patient condition parameter for each time interval of a plurality of time intervals, at least one visual representation of ventilation information, and a visual indication of when at least one patient condition parameter is outside of a target range.

A method and apparatus to determine body composition of a subject is disclosed. Physical characteristics of a subject and water in a pool is determined. A body of the subject is completely submerged in the pool of water such that a head of the subject is just below a surface of the water in the pool. The subject completely exhales air into an air measuring device as the body of the subject is submerged just below the surface of the water. A semi-rigid strip or tab portion may be coupled to the air measuring device to indicate when air pressure within the air measuring device is between a predetermined range. The body composition is then determined based on the determined subject characteristics, water characteristics and the amount of air exhaled into the air measuring device when the air pressure is between the predetermined range.

Brain activity, and in particular which hemisphere is relatively more effective, is correlated with the dominant nostril (i.e., the nostril through which most of the air is exhaled when breathing through the nose). Thus, identifying which of the nostrils is dominant may have various applications. Described herein are systems and methods for identifying the dominant nostril. In one embodiment, a system includes at least one inward-facing head-mounted thermal camera (CAM) and a computer. The at least one CAM does not occlude any of the user's mouth and nostrils and is used to take thermal measurements of first and second regions below the right and left nostrils (TH.sub.ROI1 and TH.sub.ROI2, respectively). The computer identifies the dominant nostril based on TH.sub.ROI1 and TH.sub.ROI2. Optionally, the computer detects, utilizing TH.sub.ROI1 and TH.sub.ROI2, the three-dimensional (3D) shape of the exhale stream from at least one of the nostrils.

The present invention discloses a method to determine the lung clearance index (LCI) or other indices of ventilation inhomogeneity of the lungs by combining two pulmonary gas exchange techniques; Inert gas rebreathing (IGR) is used for rapid wash-in of the inert tracer gas and this is followed by multiple-breath wash-out (MBW). The functional residual capacity (FRC) can either be determined from the tracer gas concentration and the gas flow inhaled and exhaled during multiple-breath wash-out or by gas analysis alone from the inert gas rebreathing. The cumulative expired volume (V.sub.CE) required to clear the inert tracer gas from the lungs is determined from the multiple-breath wash-out, and LCI is calculated as the ratio between V.sub.CE and FRC. The advantages of the method are i) significant reduction of required test time, ii) significant reduction of consumed gas mixture for wash-in of tracer gas, iii) potential for further reduction of the use of tracer gas, and iv) potential for more accurate determination of the FRC by gas dilution alone. Furthermore the present invention relates to a corresponding system and computer-readable medium.

The present invention is related to the field of bio/chemical sensing, assays and applications. Particularly, the present invention is related to collecting a small amount of a vapor condensate sample (e.g. the exhaled breath condensate (EBC) from a subject of a volume as small as 10 fL (femto-Liter) in a single drop), preventing or significantly reducing an evaporation of the collected vapor condensate sample, analyzing the sample, analyzing the sample by mobile-phone, and performing such collection and analysis by a person without any professionals.
