Greetings DanaMarie01! Welcome to the Heart disorder health boards!
I hope all is continuing to improve. It might be that the lowered consciousness is because of medicines given for pain or other problems that sometimes happen after surgery. Sometimes electrolytes may be off and can be asked about. If desired a person could ask the doctor why he is not alert as usual to see what they say. Usually after most surgeries they ask a person to turn cough and to breathe deeply. This may help relieve the lungs of congestion and may even prevent pneumonia. Of course every person makes their own health care decisions in life and is in charge of their own healthcare. Peace sjb
