SYSTEMS , DEVICES, AND METHODS FOR PERFORMING TRANS-ABDOMINAL FETAL OXIMETRY AND/OR TRANS-ABDOMINAL FETAL PULSE OXIMETRY USING DIFFUSE OPTICAL TOMOGRAPHY

Fetal tissue oxygenation may be performed transabdominally by, for example, receiving a plurality of detected electronic signals that correspond to light emitted from a pregnant mammal's abdomen and a fetus contained therein that has been detected by the detector and converted into the detected electronic signal. An indication of a depth of the fetus within the pregnant mammal's abdomen may be received and a portion of the detected electronic signals that correspond to light that was incident upon the fetus may be isolated responsively to the indication of the depth of the fetus using, for example, time of flight of photons that correspond to the detected electronic signals. A fetal tissue oxygen saturation level may then be determined using the isolated portion of the detected electronic signals that correspond to light that was incident upon the fetus.

Apparatus and method for determining physiological parameters of an infant in-utero
11071481 · 2021-07-27 · ·

Described herein is an apparatus to detect fetal acidosis during labor. This apparatus, which is noninvasive to the fetus, has a pH sensor and at least one fetal tissue detector. When the apparatus is inserted into the vaginal canal of a patient during labor, the pH reading determined by the pH sensor correlates to the pH of the fetus's blood. The fetal tissue detector may be a pulse oximeter, which may allow for a user to obtain the pulse rate reading of a surface contacted by the pH sensor. This pulse rate reading may be compared to an external reading of a pulse rate of the patient to confirm whether the pH sensor is contacting the fetus. During travel through the vaginal canal, the pH sensor may be protected by a protective sheath with an area of weakness to allow exposure of the pH sensor when the fetus is reached.

The assembly includes a strip having first and second ends and openings along its length, first and second fixation devices, each device having first and second surfaces, the first surface having adhesive thereon. A protuberance extends outwardly from the second surface. The assembly includes a fetal heart transducer. The first fixation device is secured to the skin at a first location and the protuberance of the first fixation device is received into a first opening on the first end of the strip. The first surface of the second fixation device is secured to the skin at a second location and the protuberance of the second fixation device is received into a second opening on the second end of the strip. The fetal heart transducer is secured between first and second fixation devices and beneath the strip.

Forecasting neonatal vitality

A decision support tool is provided for predicting the neonatal vitality scores of a fetus during delivery, the scores being an indicator of future health for the infant anticipated to be born within a future time interval, measured as time to birth. The predicted neonatal vitality score is determined from measurements of physiological variables monitored during labor, such as uterine activity and fetal heart rate. Fetal heart rate variability and patterns may be detected and computed using the monitored physiological variables, and neonatal vitality scores may be predicted based, at least in part, on the variability metrics and fetal heart rate patterns. Scores may be predicted for different delivery methods, such as vaginal delivery or cesarean delivery, for different time-to-birth intervals. In this way, these scores may be used for decision support for care plans during labor, such as increased monitoring and/or modifying the delivery type.
