A combined physiological sensor and methods for detecting one or more physiological characteristics of a subject are provided. The combined sensor (e.g., a forehead sensor) may be used to detect and/or calculate at least one of a pulse blood oxygen saturation level, a regional blood oxygen saturation level, a respiration rate, blood pressure, an electrical physiological signal (EPS), a pulse transit time (PTT), body temperature associated with the subject, a depth of consciousness (DOC) measurement, any other suitable physiological parameter, and any suitable combination thereof. The combined sensor may include a variety of individual sensors, such as electrodes, optical detectors, optical emitters, temperature sensors, and/or other suitable sensors. The sensors may be advantageously positioned in accordance with a number of different geometries. The combined sensor may also be coupled to a monitoring device, which may receive and/or process one or more output signals from the individual sensors to display information about the medical condition of the subject. In addition, several techniques may be employed to prevent or limit interference between the individual sensors and their associated input and/or output signals.

Combined physiological sensor systems and methods

An endoscope system is provided with a graphical orientation indicator. An endoscope includes a flexible tubular body with a steerable distal end having a camera. A controller for the endoscope presents a user interface that displays a view from the camera and a graphical orientation indicator visually representing an orientation of the distal end of the endoscope.

User interface for steerable endoscope

Various embodiments of a tracheal tube capable of suctioning accumulated mucus secretions from the airway of intubated patients are provided. Disclosed embodiments include a variety of endotracheal tubes with integral suction lumens terminating in ports optimally located at the distal end of the endotracheal tubes between a Murphy's Eye and a cuff. During intubation, the foregoing features, among others, of the tracheal tube may have the effect of preventing bacterial colonization of the respiratory airway and the subsequent development of ventilator associated pneumonia (VAP) in the lungs.

Endotracheal tube with dedicated evacuation port

An apnea analysis system may include a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. An apnea analysis system includes a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. The PPG sub-system is configured to be operatively connected to an individual and output a PPG signal from the individual. The breath detection sub-system is configured to be operatively connected to the individual and output a breath signal from the individual. The apnea analysis module is in communication with the PPG sub-system and the breath detection sub-system. The apnea analysis module analyzes the breath signal and a respiratory component of the PPG signal and, based on the analysis, identifies a presence of apnea, differentiates between obstructive apnea and central apnea, and provides an indication of the identified apnea.

Apnea analysis system and method

According to various embodiments, a regional oximetry sensor may include a light emitting element configured to emit light, a light detector configured to receive the light, and a memory device configured to store a baseline. The baseline stored by the memory device enables a regional oximetry monitor to display the baseline on a display of the regional oximetry monitor.

System and method for storing and providing patient-related data

Embodiments of the present disclosure relate to a system and method for determining a physiologic parameter of a patient. Specifically, embodiments provided herein include blood pressure cuffs that are adapted to be used in conjunction with a photoplethysmography sensor. The cuff as provided may be configured to be placed over the sensor and/or aligned in a specific manner relative to the sensor. Alternatively, the cuffs may include integral optical components.

Method and apparatus for noninvasive blood pressure measurement using pulse oximetry

During patient monitoring, a depth of consciousness (DOC) measure, such as a bispectral index, may be used in conjunction with additional information obtained from an awareness metric derived from one or more physiological signals, such as a photoplethysmograph signal. In an embodiment, a DOC measure may be combined with information from an awareness metric to produce a combined DOC measure. In an embodiment, information from an awareness metric derived from one or more physiological signals may be used to provide an indication of confidence in a DOC measure. In an embodiment, a DOC measure may be used to provide an indication of confidence in a depth of consciousness assessment based on an awareness metric. In an embodiment, one or the other of a DOC measure and an awareness metric may be used to provide an indication of a patient's depth of consciousness (e.g., by one 'overriding' the other).

Systems and methods for monitoring depth of consciousness

Embodiments described herein may include systems and method for monitoring physiological parameters of a patient. Specifically, embodiments disclose wireless, reusable, rechargeable medical sensors that include an inductive coil coupled to a rechargeable battery. Additionally, embodiments disclose systems and methods for recharging and disinfecting the disclosed medical sensors.

Methods and systems are provided that allow for the simultaneous calculation of pulse and regional blood oxygen saturation. An oximeter system that includes a sensor with a plurality of emitters and detectors may be used to calculate a pulse and/or regional blood oxygen saturation. A plurality of light signals may be emitted from light emitters. A first light signal may be received at a first light detector and a second light signal may be received at a second light detector. A pulse and/or regional blood oxygen saturation value may be calculated based on the received first and/or second light signals. The pulse and regional blood oxygen saturation values may be calculated substantially simultaneously. The calculated pulse and regional blood oxygen saturation values as well as other blood oxygen saturation values may be displayed simultaneously in a preconfigured portion of a display.

Simultaneous measurement of pulse and regional blood oxygen saturation

Embodiments of the present disclosure relate to techniques for controlling the temperature of light sources within physiological sensors in order to regulate the wavelengths emitted by the light sources. The sensors may include a temperature control element that is designed to provide heating and/or cooling to the light sources. The sensors also may include a temperature sensor designed to detect the temperature of the light sources. Based on the detected temperature, a controller can vary the amount of heating and/or cooling provided by the temperature control element to maintain the temperature of the light sources at a desired temperature or within a desired temperature range.

Medical sensor with temperature control

Various embodiments of a secretion collection and/or sample analysis device are provided for point-of-care collection and/or analysis of secretions collected from the airways of intubated patients. The disclosed embodiments include a variety of placements of the device with respect to a tracheal tube that include in a secretion reservoir, between an evacuation conduit and the secretion reservoir, and connected in series after the evacuation conduit and the secretion reservoir. Certain embodiments may include a lab-on-a-chip device that analyzes secretions via polymerase chain reaction (PCR) based DNA sequencing.
