    摘要: A patient monitoring system may provide photoacoustic sensing based on an indicator dilution to determine one or more physiological parameters of a subject. The system may detect an acoustic pressure signal, which may include one or more thermo-dilution responses, one or more hemo-dilution responses, or a combination thereof. For example, a thermo-dilution indicator and/or a hemo-dilution indicator may be used to determine one or more hemodynamic parameters. In a further example, an isotonic indicator and a hypertonic indicator may be used to determine one or more hemodynamic parameters of the subject.

    摘要: Embodiments of the present disclosure relate to a system and method for non-invasively determining a cardiac output of a patient that may include a photoacoustic sensor and a determination of oxygen uptake of the patient. Specifically, a signal from a photoacoustic sensor may be used to determine a mixed venous and an arterial oxygen saturation of the patient. The parameters of mixed venous and arterial oxygen saturation in conjunction with oxygen uptake may be used to calculate cardiac output using the Fick method.

    摘要: A patient monitoring system may use photoacoustic sensing to determine one or more physiological parameters of a subject. The system may detect an acoustic pressure response generated by the application and absorption of light, which may be used to identify the size of a blood vessel. The blood pressure of a subject may calculated based on the measured blood vessel size and calibration values. One or more calibration values may be determined based on a known relationship between a change in blood vessel size and a change in blood pressure.
