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： Multi-wavelength photon density wave (PDW) medical systems, methods, and devices are provided. In one embodiment, a multi-wavelength system may include a sensor, a sensor cable, and a patient monitor. The sensor may have an emitter and a detector configured to pass a multi-wavelength PDW input signal into a patient and receive a resulting multi-wavelength PDW output signal. The sensor cable may couple to the sensor and include two optical cables for transmitting and receiving the multi-wavelength PDW signals. The patient monitor may couple to the sensor cable and generate several single-wavelength PDW input signals by modulating a plurality of light sources. The monitor may include an optical switch configured to time-division multiplex the several single-wavelength PDW wave input signals by selecting one of the single-wavelength PDW signals at one time to produce a multi-wavelength PDW signal which is output from the monitor to the sensor via the sensor cable.

摘要： According to various embodiments, methods and systems for determining pressure in the lungs may employ intracuff pressure measurements. The intracuff pressure measurements may calibrated or adjusted based on a set of calibration coefficients or a set of calibration curves, which may reflect patient parameters and cuff/tube geometry factors. The resulting calibration may be used to determine a more accurate estimate of lung pressure, which in turn may be used to control a ventilator and provide breathing assistance to a patient. Also provided are tracheal tubes with couplers or other memory devices for storing calibration information. Such tubes may allow calibration at the level of an individual tracheal tube to account for changes in tube geometry and individual patient factors.
