After 2 weeks I am distressed I still feel the swooshing electrical feeling in my head.
Incorrect placement of the transducer may detect a pulsating maternal vessel with a resultant swooshing sound (uterine soufflé), and the rate will be the same as the maternal pulse.
They all sit down, flap their arms and make jet swooshing sounds as if they are flying.
Our sleep was occasionally disturbed by a bizarre swooshing noise upon which was superposed some bird sounds.
