Not necessarily - sometimes lasix makes it less, sometimes it makes it stop completely, sometimes it doesn't do anything. Overall yes, lasix vastly reduces the incidence of detection of bleeding due to EIPH in horses, including stopping it in some horses.

Here's a cross section of lung (viewing it from the horses left side, the front of the horse is on the left) showing where bleeding occurs, the top (dorsal) back (caudal) part of the lung. We only detect blood when it comes out of the lungs up into the trachea. The trachea isn't shown here, it would be to the left of the lungs:





Here's a horse bleeding so bad blood is bubbling out of the lungs, up the trachea, and out the nose. Only 1 out of 20 will bleed so badly this is seen:



Here's a horse with a little blood in the trachea via bronchoscopy:
