The respiratory therapist (Catherine) just came in and said that 'no one is comfortable with weaning her today'. So basically that means at least 24 more hours on the ventilator. They want to give her body a chance to rest from all the waking up she did yesterday and all the stress her pulmonary vessels endured everytime she woke up.
They also want to give the Viagra a chance to work (to dialate her pulmonary vessels) so that when they wean her off the sedation medication, her lungs don't constrict and her pressures don't get out of control like they did yesterday.
She's peacefully resting right now. They switched her sedative medicine from Versed to Ativan this morning hoping she'll rest a little more comfortably for a longer period of time (instead of waking up every hour for another shot of Versed). Right now a lab tech is in the room doing an echocardiogram (ultrasound of Scarlett's heart). Just to get a picture of the pressures of the cardiac veins/arteries and overall pumping function of Scarlett's new heart.
