Methods and systems are provided for determining physiological information based on distortion factors and physiological signals. Physiological signals are received by a system. The system may receive or determine a value indicative of oxygen saturation. The distortion factors may be calculated based on the value indicative of oxygen saturation and the physiological signals. The distortion factors may be used to determine physiological information.

Methods and systems for determining physiological information based on distortion information

The present disclosure relates generally to patient monitoring systems and, more particularly, to a resistance emulator for patient monitors. In an embodiment, a resistance emulator includes a first plug configured to couple with a medical monitor. The medical monitor is configured to receive a calibration resistance value of a medical device sensor from a coded resistor. The resistance emulator further includes a second plug configured to couple with a medical device sensor. The medical device sensor is configured without the coded resistor. The resistance emulator also includes emulation circuitry configured to provide an emulated signal representative of the calibration resistance value to the medical monitor.

Calibration resistance emulator

A system and method for generating results indicative of physiological parameters of a patient and for capturing the results. The capture of the results may include recordation of the results through the use of a camera, while the physiological parameters may be generated through monitoring of a patient or by simulating such monitoring.

Medical monitor data collection system and method

An evaluation board for a medical monitoring module is provided. The evaluation board includes a socket configured to receive a medical monitoring module and a plurality of connections for connection to a host or host simulator and a second device. The evaluation board may include a non-isolated power supply to provide power to the medical monitoring module. The evaluation board may also provide communication in a protocol between the host or host simulator and the medical monitoring module.

Evaluation board for a medical monitoring module system and method

Systems, methods, and devices are provided for suppressing cross-talk noise due to capacitive and/or inductive coupling in a medical sensor signal. For example, an embodiment of a patient monitor may include driving circuitry, an amplifier, and transient current discharge circuitry. When the driving circuitry drives an emitter to emit light into a patient, a detector may detect a portion of the light that passes through the patient, generating a detector signal. Cross-talk between the emitter driving signals and the detector signal may generate interference in the form of a transient current in the detector signal. Before the amplifier receives the detector signal, transient current discharge circuitry may discharge the transient current.

Cable cross talk suppression

An evaluation kit for monitoring, testing, and debugging a medical monitoring module is provided. The kit includes a hardware and software to provide for monitoring of communication between the medical monitoring module and a host or host simulator. The kit may provide for various system configurations having a sensor device, a computer having a protocol analyzer and a host simulator, a medical monitoring module, a software host, a medical monitor, or any combination thereof.
