<s>[INST] MY FATHER 82 WAS JUST TOLD HE HAS 10 PERCENT HEART FUNCTION, 25 PERCENT LUNG FUNCTION, HIS BODY TEMP IS 34.2 AND BP AVERAGES AROUND 85/40  HE HAS A CATHEDAR AND SLEEPS MOST OF TIME, HE IS CONFUSED AND STRUGGLES TO BREATH.  WE ARE AFRAID TO LEAVE, INCASE HE DIES WITHOUT US.  DO THESE SYMPTOMS MEAN DEATH IS NEAR [/INST] Left ventricle ejection fraction less than 355 is considered as critical, your father has an EF of 10%,this means supposes if heart has to pump 100ml of blood your father heart is pumping only 10ml of bloods blood pumped outside is very low therefore it cannot maintain the blood pressure also as a consequence blood pressure is also very lows blood perfusion in every part of body is very important to maintain temperature of body his body temp is also low.....all these things are interconnected....as blood reaching the brain is less he is clumsy and confused you have not mentioned his age but left ventricular assisted device implantation followed by cardiac transplant is the only option left at such a low but it's a very costly procedure needs a brain-dead heart donor thank you </s>
