FREAKING OUT PLEASE HELP!!

I have an owlet for my son he's 2 months almost 3 months old.. well he sleeps in his crib and about 20 minutes ago the owlet started blinking red that his heart rate was 2 low.. it dropped below 60 beats per minute.. I'm like freaking out!! This is the first time this has happened . He always sleeps in the corner of his crib in a ball.. anyone have any idea why his heart rate dropped??? This is the first time this has happened...
