Publication number: 20220400965Abstract: A hemodynamic monitoring system monitors arterial blood pressure of a patient and provides a warning to medical personnel of a predicted future hypotension event of the patient. Waveform analysis is performed on sensed hemodynamic data representative of an arterial pressure waveform of the patient to determine a plurality of hypotension profiling parameters predictive of a future hypotension event for the patient. A set of transformed hypotension profiling parameters is generated based on the hypotension profiling parameters and mean and standard deviation values of the hypotension profiling parameters at a standard mean arterial pressure (MAP) threshold for hypotension and an adjusted MAP threshold for hypotension. A risk score representing a probability of a future hypotension event for the patient is determined based on the set of transformed hypotension profiling parameters. A sensory alarm is invoked to produce a sensory signal in response to the risk score satisfying a predetermined risk criterion.Type: ApplicationFiled: August 24, 2022Publication date: December 22, 2022Inventors: Brennan Michael Schneider, Zhongping Jian, Feras Al Hatib, Sai Prasad Buddi

Publication number: 20220395236Abstract: A hemodynamic monitoring system monitors arterial blood pressure of a patient and provides a warning to medical personnel of a predicted future hypotension event of the patient. Sensed hemodynamic data representative of an arterial pressure waveform of the patient are received by a hemodynamic monitor. The received hemodynamic data is offset, based on a difference between a standard mean arterial pressure (MAP) threshold for hypotension and an adjusted MAP threshold for hypotension, to produce adjusted hemodynamic data. Waveform analysis of the adjusted hemodynamic data is performed, and a risk score representing a probability of a future hypotension event for the patient is determined based on the waveform analysis. A sensory alarm is invoked to produce a sensory signal in response to the risk score satisfying a predetermined risk criterion.Type: ApplicationFiled: August 24, 2022Publication date: December 15, 2022Inventors: Sai Prasad Buddi, Brennan Michael Schneider, Zhongping Jian, Feras Al Hatib

Publication number: 20210310840Abstract: Described herein are thermal mass flow sensors that combine calorimetric and anemometric (e.g., hot-wire) elements to provide a hybrid approach to determining flow rate of a liquid. The flow probes or flow sensors are configured to use a heater to apply heat to a thermally-conducting material in contact with the flowing liquid, to measure a temperature of the thermally-conducting material upstream of the heater and downstream or at the heater, to adjust power to the heater to achieve a targeted temperature difference, and to determine a flow rate based at least in part on the power supplied to the heater and the measured temperatures. This approach provides flow rate due at least in part to the fluid cooling the thermally-conductive material proportionate to flow rate with non-linear effects. This hybrid approach can provide accurate readings of flow rates of liquids delivered through an IV line to a patient.Type: ApplicationFiled: June 18, 2021Publication date: October 7, 2021Inventors: Cole Emerson Feagler, Sakyasingh Tripathy, Brian Ray Hipszer, Feras Al Hatib, Hengchu Cao

Publication number: 20180353680Abstract: Disclosed herein are devices, systems, and methods that automate the identification of the start and end of a fluid bolus and calculate the volume of fluid given during the challenge. A flow measurement device is used to measure fluid flow in a conduit (e.g., IV tubing) and an algorithm is used to determine a start time and the stop time of a fluid bolus. In addition, the volume of fluid given during the bolus is calculated. Advantageously, this provides accurate and automatic collection of the start time of the fluid bolus, the income of the fluid bolus, and the volume of the fluid bolus. Historically, these data are estimated by the clinician used to assess the hemodynamic response to the fluid bolus.Type: ApplicationFiled: June 8, 2018Publication date: December 13, 2018Applicant: Edwards Lifesciences CorporationInventors: Feras AL HATIB, Morgan T.
