Patent number: 12263018Abstract: A portable spot-check system configured to assess the validity of a measured physiological parameter. The spot-check device can take into consideration a variety of factors to determine whether a valid measurement exists. For instance, the considerations can include signal stability, interference, signal IQ, patient movement, sensor position, timing of that measurement, comparison to previous or acceptable measurements, cancellation of measurement by the patient, confidence of the measurement, etc. The spot-check device can track a number of valid measurements. In some instances, the spot-check device is configured to provide a specified number of available measurements. If a valid measurement is recorded, the spot-check device can decrement the remaining number of available measurements.Type: GrantFiled: November 23, 2020Date of Patent: April 1, 2025Assignee: Masimo CorporationInventors: Bilal Muhsin, Prashanth Rengaswamy Chandran, Mihir Chinchalkar, Prashanth Iyengar, Ammar Al-Ali, Ronald Keith Rumbaugh, II, James Pishney

Patent number: 12232888Abstract: A patient monitor can noninvasively measure a physiological parameter using sensor data from different measurement sites on a patient. The patient monitor can combine all sensor data from different measurement sites into a raw or minimally processed data form to generate a single, robust measurement of the physiological parameter. An optical sensor of a patient monitor can include multiple photodetectors each configured to generate a signal when detecting light attenuated by the patient's tissue. A measurement of a physiological parameter can be determined based on at least in part on the multiple signals from the multiple photodetectors.Type: GrantFiled: October 20, 2022Date of Patent: February 25, 2025Assignee: Masimo CorporationInventors: Vikrant Sharma, Philip Perea, Prashanth Iyengar

Patent number: 12167913Abstract: Embodiments of the present disclosure provide a hypersaturation index for measuring a patient's absorption of oxygen in the blood stream after a patient has reached 100% oxygen saturation. This hypersaturation index provides an indication of the partial pressure of oxygen of a patient. In an embodiment of the present invention, a hypersaturation index is calculated based on the absorption ratio of two different wavelengths of energy at a measuring site. In an embodiment of the invention, a maximum hypersaturation index threshold is determined such that an alarm is triggered when the hypersaturation index reaches or exceeds the threshold. In another embodiment, an alarm is triggered when the hypersaturation index reaches or falls below its starting point when it was first calculated.Type: GrantFiled: June 21, 2021Date of Patent: December 17, 2024Assignee: Masimo CorporationInventors: Mohamed K. Diab, Prashanth Iyengar, Anand Sampath, Ammar Al-Ali
