The heart and lungs

The split, the shunt, the descending aorta.

on a boring day, thank the Creator for this boring day,

we can discuss over dinner how the heart and lungs work.

enjoying homemade apple pie with vanilla ice cream,

we watch a video on pulmonary hypertension, 

and follow up with sketches and annotations,

Susan asks for a copy; Karen says my handwriting is too messy.

I'll understand now when Daniel tells me about right to left shunt

(really bad) where de-oxygenated blood flows into oxygenated blood,

or left to right shunt (bad, but not as bad) when oxygenated blood flows

back into the de-oxygenated blood heading to the lungs.

and the split, having to do with valves not closing at the same time,

when they should, because pressures are wrong.  

I understand this now.

I hope for more boring days where baby steps are taken

toward recovery, that our Owen will be able to come home.

soon.
