Prayers for Daddy

Hey Y'all! I hope you're having a wonderful week so far. This past Thursday ended our first semester, so Friday and Monday were Teacher's Workdays. I had planned on working Friday and then taking off Monday. Thursday morning my daddy had a dr. appt that was encouraged by me and my sister. Daddy has really high blood pressure and was having some issues and some chest/neck pains. Thus the appt....
When he finally got to see the doctor, she checked his blood pressure and it was 210/144. She sent him home to get some things together and then to the hospital. Upon admittance, they checked it again and it was 250/122. He was immediately put into ICU on the heart floor and they began an IV with a Nitro drip--this continued for 36 hours. Finally on Saturday night, he was put into a regular room. Monday, they gave him a stress test via IV and we are STILL waiting on the results. If nothing shows up, they're supposed to send him home. If something DOES show up, we'll go from there. I've had my Facebook family and the rest of my friends and family praying for my daddy, and now I'm asking y'all. Some of y'all are regulars and know how close my family is. My daddy is aggravated and is wanting to come home. Mama just texted me his information...BP is 136/76, pluse is 50 and oxygen levels are in the 90s. This is good for now, so we wait. Would you please join my family in prayer in hopes that God will work everything out for Daddy?
Thanks!
