Roscoe is on heavy sedatives which are gradually being decreased. His heart rate remains high due to his pulmonary hypertension, but also because he is being given albuterol (an inhalant that improves lung function) and diuretics (to get rid of excess fluids). Both the albuterol and diuretics have the potential to raise his heart rate. He will look normal and comfortable, but when he is awake his heart rate got into the 180-190 range if he was even mildly active. When he is in a deep sleep his heart rate will be 160, when previously it hovered around 90-100 in deep slumber.
To combat the high heart rate, Alisha and I will read books to him. Though he is sleeping, we know that he hears our voice and it comforts him. The pictures below are of Alisha reading him a book to get him to settle down and to remind him that she's still there, even though he can't see her:
I am proud of Alisha for undergoing such a tumultuous time and still being brave enough to remain positive for Roscoe's benefit, and still having faith in God when immediate healing hasn't been granted (though we've asked time and time again).
