A base unit operable with a wireless patient monitoring unit used to acquire physiological data during an MRI examination is constructed to have a detachable display unit. The detachable display unit wirelessly communicates with the base unit when in a roving mode. The detachable display unit may also have a magnetically-hardened power supply that does not saturate during an MRI examination. Such a magnetically-hardened power supply allows the display unit to operate when proximate or in the magnetic field generated by an MRI machine during an MRI examination.

A wireless patient monitor for MRI provides for on-board filtering of physiological signals from the patient to provide improved assessment and processing of MRI noise before the signal is affected by the transmission process. A system of powering of a wireless patient monitor using capacitors is also provided.

Wireless patient parameter sensors for use in MRI

An apparatus is provided for detecting each of the five known anesthetic agents, CO,, and N,O when monitoring a patient's respiratory gas stream during anesthesia. A source of infrared radiation emits the infrared tight through a gas stream and onto the infrared detector/sensor. The detector may contain ten analytical channels, each channel containing an independent infrared detector and a specific bandpass infrared filter which only permits certain wavelengths of the infrared radiation to reach the respective infrared detector. One of the channels is a blocked detector which serves as the reference point. A calibration and processing means is also provided to compensate for factors such as offset voltage, cross coupling, wideband changes and thermal drifts which may affect the accuracy of the gas measurements.
