INFANT® is software to interpret fetal heart rate monitoring that took us over 27 years to develop. It has taken this time because correct CTG interpretation is difficult. On the one hand INFANT® must be good at detecting problems within all manner of patterns and on the other hand it must not be over sensitive so as to raise concern unnecessarily. Achieving this balance is very hard, for human and computer. INFANT® analyses the FHR and contraction pattern and alerts clinicians to potential problems in a timely way. INFANT® has been validated on databases of several thousand interesting, abnormal and challenging traces and has been found to perform at the level of experts whose ability we have measured.
INFANT® is a software module that runs within our K2MS Guardian™ Electronic Patient Records computer system for labour and delivery. INFANT® runs in real time at the bedside using a direct feed from the fetal monitor. The Guardian™ system communicates INFANT® all around the hospital network so that all monitoring can be viewed at central stations, offices or remotely from home to ensure that all CTGs of concern are flagged to senior staff wherever they may be.
INFANT®’s algorithms have been modelled on human expert interpretation and has been measured and assessed in a paper that compared its performance to 17 human experts. INFANT® analyses the same features of a CTG trace that an expert would do, Baseline, Variability, Accelerations and Decelerations (type and timing, depth, duration and area), Signal Quality, Contractions (location and frequency, and whether they are pushing), Sinusoidal and Bimodal patterns; all the features that clinicians are familiar with. INFANT® also has algorithms for the detection of maternal heart rate patterns to avoid cases where the maternal heart rate has been inadvertently recorded instead of the fetal rate. This also works for twins.
