My father had bronchial artery Embolization for arteries in right lung. His right lung was damaged due to many issues earlier. He was feeling after BAE that day but next day night he was feeling dizzy, went to bathroom, couldn't pass urine and came back sat on bed, he was tired. We tried to pull him back a little to help him lie down, during this time he experienced cough, blood vomited with heart failure. So question is, does this pull to help him lie down contributed to above heart failure?
