Abstract: A method and chart for alerting a medical caregiver to undetected or developing complications associated with, or resulting from, initially diagnosed or suspected medical problems. First, a list is prepared of possible complications that might occur based upon the initial diagnosis. Signs of the complications are concisely listed on the chart. The concise chart is posted at, or is otherwise available or near the patient's location, such as at a hospital bed or nurse's station, or other easily observable locations. Thereafter, various caregiver personnel who attend to, or routinely visit, the patient for performing various services, routinely check the listed signs against the patient's condition when the patient is visited. Each caregiver person records the presence of, and any observed changes in, the listed signs that are observed giving the time of the observation. Lastly, an appropriate caregiver physician is alerted to the noted signs for diagnosing and prescribing appropriate treatments.

Abstract: Some engine applications place spatial constraints on heat exchangers, such as oil coolers. In such a case, a heat exchanger having an oblong rather than a circular cross section can satisfy spatial constraints, and with certain internal geometry, may permit improved heat rejection performance while potentially enabling a cost reduction through a reduction in materials. The heat exchanger has a housing which defines a heat exchanging cavity within which a tube bundle is positioned. The tube bundle is made up of a plurality of tubes in a hexagonal packing pattern that are supported by a plurality of baffles. The tube bundle and the housing define a serpentine flow path between an inlet and an outlet. The serpentine flow path includes a plurality of segments that are generally perpendicular to the tubes, and these segments are separated by flow direction changing windows.
