During the fetal period, the baby doesn’t need to breathe — no air around, after all — and so the fluid-filled lungs are short circuited by the ductus arteriosus which allows the baby’s blood flow to bypass the lungs. Normally, it closes shortly after birth, but in Sarah’s case, it remained open. After birth, the pressure differentials shift, and the ductus arteriosus now shunts some oxygenated blood away from the arterial circulation and into the venous circulation. If I understand what House is implying, Sarah’s PDA isn’t open all the time, but just under periods of stress, which causes her systemic blood pressure to rise. During these periods, enough oxygenated blood is lost so that the brain doesn’t get as much as it needs (but apparently this affects just the left side of Sarah’s brain) and this is what causes the dropping blood pressure in her brain and her neurological symptoms. The shift in pulmonary blood flow led to her lung symptoms. The abnormal turbulence from this can tear up platelets, so this is most likely what led to her abnormal platelets and bleeding problems.

“The CLIQ is without a doubt geared towards the younger generation, and the design embodies that. It is on the small side, which means a smaller screen and keyboard, but is still heavy. It has a good weight to it, but we’re not crazy about the feel. When closed the slider is loose and when held by the bottom half the top piece will wiggle, but thankfully this goes away when opened. Still, the CLIQ isn’t exactly what we’d call solid, and the cheap plastic housing doesn’t do much to reassure us.The 3.1â€Â capacitive HVGA display is quite nice. The 262K colors offer more depth than screens we’ve seen from HTC and it is plenty responsive.  It’s a far cry from the DROID, but that is to be expected.  Below the display are physical Home, Menu and Search buttons.  On the left side is a vibrate toggle (something we’d love to see more of,) volume rocker and microUSB charging/data port.  The right side has the lock/power button and camera key. The side keys are all very shallow and could use a bit more travel for reassurance.   The top simply features the 3.5mm headphone jack.” Read more here:
