An embodiment of the present invention is a nasal cannula for delivering continuous positive airway pressure (“CPAP”) to a patient's nares during operative procedures or in critical care areas. A malleable metal or plastic is encased in the bridge of the cannula to allow it to be shaped to the patient's face. As a result of contouring the cannula to the face, air leaks are minimized allowing a seal to be provided when an op site is applied to cover the upper lip, nasal cannula and nose. The cannula's nasal inserts can end in nontapered or slightly tapered non-sealing beads, which may be slightly angled out to accommodate various facial anatomies. When approximately several liters per minute of oxygen are flowed through the cannula, CPAP is obtained.

Ischemia-reperfusion injury commonly results from any surgical procedure requiring stopping of blood supply to an organ followed by reperfusion such as in heart bypass, angioplasty or organ transplant. The invention discloses a method to harness the innate power of repetitive transient ischemia in protecting organs against imminent ischemia-reperfusion, or any patho-physiological insults. This method of optimal remote ischemic preconditioning (ORIP) comprises of utilizing a pair of programmable pneumatic cuffs that inflate/deflate alternately occluding blood circulation to each of the limbs for pre-defined time intervals. The apparatus delivers maximal ORIP dose in shortest possible time either as an EMS procedure during patient transportation to hospital, as elective pre-surgery treatment, or in critical care for preventing multiple-organ-dysfunction-syndrome. ORIP can be self-administered and remotely monitored by clinician especially in chronic patients for homeostasis of malfunctioning target organs. ORIP may also be deployed as adjunct in angioplasty, gene/stem cell heart repair therapies.

A disease-specific ontology crafted by a consensus of expert clinicians may be used to semantically characterize/provide semantic meaning to dynamically changing patient electronic medical record (EMR) data in critical care settings. Hierarchical, directed node-edge-node graphs (concept maps or Vmaps) developed with an end-user friendly graphical user interface and ontology editor, can be used to represent structured clinical reasoning and serve as the first step in disease-specific ontology building. Disease domain Vmaps reflecting expert clinical reasoning associated with management of acute illnesses encountered in critical care settings (e.g. ICUs) that extend core clinical ontologies, developed and reviewed by experts, are in turn extended with existing medical ontologies and automatically translated to a domain ontology processing engine. Semantically-enhanced EMR data derived from the ontology processing engine is incorporated into both real-time ‘track and trigger” rule engines and machine learning training algorithms using aggregated data. The resulting rule engines and machine-learnt models provide enhanced diagnostic and prognostic information respectively, to assist in clinical dual modes of reasoning (analytical rules and models based on experiential data) to assist in decisions associated with the specific disease in acute critical care settings.

The bypass flow channel includes a flow-restrictor (e.g, an orifice) that partially blocks the flow of respiratory gas through the bypass flow channel, a mixing chamber positioned upstream of the flow restrictor and a sampling apparatus (e.g., a port for withdrawing samples of gas from said mixing chamber and/or sensor(s) positioned within the mixing chamber).

Systems for rapid and accurate analyte measurement are described. For example, periodic glucose measurements can be achieved with high accuracy in a critical care environment by drawing blood into a device more than once per hour, analyzing blood (for example using infrared radiation through plasma). Safety and accuracy can be achieved by improved fluid control and avoidance of clotting. Data can be conveyed (e.g., displayed) to a user. A user can be allowed to annotate the data. For example, a touchscreen or other interface can allow addition of notes on a running graph of data, indicating events or other items of interest that may correspond to data readings or to particular times.
