Abstract: The present disclosure includes a portable physiological monitor including a first local display and configured to communicate with a second physiological monitor including a second display.

Abstract: The present disclosure includes a pulse oximeter attachment having an accessible memory. In one embodiment, the pulse oximeter attachment stores calibration data, such as, for example, calibration data associated with a type of a sensor, a calibration curve, or the like. The calibration data is used to calculate physiological parameters of pulsing blood.

Abstract: A sensor, such as, for example, a gravity-responsive sensor, provides an output used to select an orientation of a display of a display device. For example, the output may indicate that the orientation of the display should comprise a portrait or landscape orientation, an orientation rotated, such as, for example, ninety degrees (90°), one hundred and eighty degrees (180°), two hundred and seventy degrees (270°), or the like. In addition, one or more manual switches, buttons, or display icons may be actuated or otherwise selected to manually set the orientation of the display.

Abstract: A real-time waveform analysis system utilizes neural networks to perform various stages of the analysis. The signal containing the waveform is first stored in a buffer and the buffer contents transmitted to a first and second neural network which have been previously trained to recognize the start point and the end point of the waveform respectively. A third neural network receives the signal occurring between the start and end points and classifies that waveform as comprising either an incomplete waveform, a normal waveform or one of a variety of predetermined characteristic classifications. Ambiguities in the output of the third neural network are arbitrated by a fourth neural network which may be given additional information which serves to resolve these ambiguities.

Abstract: A system which provides information necessary to diagnose a failure or malfunction of an oxygenator. The system provides information to differentiate oxygenator failure from other causes of hypoxemia (inadequate blood oxygen concentration). Such as malfunction of the ventilating circuit, or components of the ventilating circuit. This is accomplished by analyzing the oxygen concentration of the ventilating gas entering the oxygenator, the flow of the ventilating gas entering the oxygenator, and also the pressure in the ventilating gas circuit or the pressure of gas within the oxygenator. As a result the invention provides information to diagnose ventilating gas flow obstruction or a gas leak from an oxygenator housing.

Abstract: A monaural stethoscope attached to a holder having a hook and loop fastening system. The holder is configured such that when the loop fastening material is folded up on itself, it mates with the hook fastening material to form a closed loop for retaining the coiled tubing of the monaural stethoscope. A pin fastener, such as a safety pin, is attached to the back of the holder so that the holder can be pinned to a medical garment, such as an anesthesiologist's scrub suit.
