    Abstract: According to certain described aspects, an acoustic sensor is employed in a variety of beneficial ways to provide improved physiological monitoring, among other advantages. In various embodiments, the acoustic sensor may include an attachment sub-assembly including a deformable portion that enables improved coupling to a patient. Additionally, the acoustic sensor may include an adhesive layer that, in combination with the deformable portion, enables even, robust, and secure attachment of the sensor to the patient. In various embodiments, an acoustic coupler having a semi-spherical shape is provided to further improve coupling of acoustic signals from the patient to the sensor.

    Abstract: According to certain described aspects, multiple acoustic sensing elements are employed in a variety of beneficial ways to provide improved physiological monitoring, among other advantages. In various embodiments, sensing elements can be advantageously employed in a single sensor package, in multiple sensor packages, and at a variety of other strategic locations in the monitoring environment. According to other aspects, to compensate for skin elasticity and attachment variability, an acoustic sensor support is provided that includes one or more pressure equalization pathways. The pathways can provide an air-flow channel from the cavity defined by the sensing elements and frame to the ambient air pressure.

    Abstract: An acoustic sensor attached to a medical patient can non-invasively detect acoustic vibrations indicative of physiological parameters of the medical patient and produce an acoustic signal corresponding to the acoustic vibrations. The acoustic signal can be integrated one or more times with respect to time, and a physiological monitoring system can determine pulse or respiration parameters based on the integrated acoustic signal. The physiological monitoring system can, for instance, estimate a pulse rate according to pulses in the integrated acoustic signal and a respiration rate according to a modulation of the integrated acoustic signal, among other parameters. Further, the physiological monitoring system can compare the integrated acoustic signal or parameters determined based on the integrated acoustic signal with other signals or parameters to activate alarms.

    Abstract: A system for generating an overdose risk score of a user includes a physiological sensor coupled to a wearable device and configured to detect attenuated light from a tissue site of the user and at least one hardware processor. The hardware processor can be configured to determine a plurality of parameters based on the attenuated light, determine a baseline risk, an instability index, an average slope, and desaturation pressure, and determine a weighted aggregate of the baseline risk, the instability index, the average slope, and the desaturation pressure for each of the plurality of parameters, determine an overdose risk score by determining a weighted aggregate of the plurality of parameters, determine an alarm level of a series of escalating alarm levels based on the overdose risk score, and implement intervention associated with the determined alarm level.

    Abstract: A pulse oximetry system for reducing the risk of electric shock to a medical patient can include physiological sensors, at least one of which has a light emitter that can impinge light on body tissue of a living patient and a detector responsive to the light after attenuation by the body tissue. The detector can generate a signal indicative of a physiological characteristic of the living patient. The pulse oximetry system may also include a splitter cable that can connect the physiological sensors to a physiological monitor. The splitter cable may have a plurality of cable sections each including one or more electrical conductors that can interface with one of the physiological sensors. One or more decoupling circuits may be disposed in the splitter cable, which can be in communication with selected ones of the electrical conductors. The one or more decoupling circuits can electrically decouple the physiological sensors.

    Abstract: A wearable device for a noninvasive measurement of a user's body temperature can include a housing, a first substrate coupled to the housing and having an opening, a second substrate coupled to the first substrate and configured to secure to skin of a user, a mounting frame enclosed by the housing and the first substrate, a circuit board secured by the mounting frame, a temperature sensor coupled to the circuit board and configured to determine a body temperature of the user, and a thermally conductive probe. The thermally conductive probe is secured by the mounting frame and positioned proximate to the first temperature sensor. The thermally conductive probe extends at least partially through the opening in the first substrate and transmits a thermal energy from a portion of the user's skin to the first temperature sensor.
