My dad had a heart attack sunday, he got admitted into a hospital & was diagnosed with pneumonia afib and renal failure. He’s been doing a lot better since then but today he had another heart attack, they were waiting on his kidneys to get better to put dye in him to see where his blockages were to put stints in. He’s now in a sedated state, & his kidneys need to do better & his blood pressure in low. When i visited him he was twitching his tongue & lips & would squeeze my fingers & grip them pretty hard, & at one point i could’ve swore he kept squeezing my hand so i couldn’t move it away like i was trying to do. Can he actually hear me or is that stuff just impulses?
