Abstract: A blood analysis system functions as a non-invasive blood parameter analyzer when a monitor is coupled with an optical sensor and as an invasive blood sample analyzer when the monitor is coupled with a blood analysis adapter. The blood analysis adapter has a transmitting assembly and a receiving assembly in electrical communications with the adapter connector so as to receive emitter signals for driving emitters within the transmitting assembly and so as to transmit a detector signal for responding to at least one detector in the receiving assembly. A cuvette containing a blood sample is irradiated with multiple wavelength light from the emitters, the detector responds to the multiple wavelength light after attenuation by the blood sample, and the monitor analyzes the blood sample according to the detector signal.

Abstract: Embodiments of the present disclosure include a handheld multi-parameter patient monitor capable of determining multiple physiological parameters from the output of a light sensitive detector capable of detecting light attenuated by body tissue. For example, in an embodiment, the monitor is capable of advantageously and accurately displaying one or more of pulse rate, plethysmograph data, perfusion quality, signal confidence, and values of blood constituents in body tissue, including for example, arterial carbon monoxide saturation (“HbCO”), methemoglobin saturation (“HbMet”), total hemoglobin (“Hbt”), arterial oxygen saturation (“SpO2”), fractional arterial oxygen saturation (“SpaO2”), or the like. In an embodiment, the monitor advantageously includes a plurality of display modes enabling more parameter data to be displayed than the available physical display real estate.

Abstract: A respiratory monitoring system can include an acoustic respiratory sensor that obtains acoustic information from a patient and one or more processors in communication with the acoustic respiratory sensor. Such processors can receive a respiratory rate value derived from the acoustic information. This respiratory rate value can reflect an averaged set of respiratory rate values over a period of time. The one or more processors can also receive an indication of a respiratory abnormality that occurred during the same time period. Further, the one or more processors can output the averaged respiratory rate value together with a respiratory event indicator reflecting the respiratory abnormality.
