I want to ask about my preterm baby.

Hello, my baby was born on 1st may 2107 10.30 morning. He was only 34 week matured. Doctors said he is having respiratory problem as his lungs are not matured. They kept him in NICU and put him on ventilator and asked me to wait for response. After 12 hour of no improvement they gave him injection of SURVANTA which is of 8 ml as my baby weight is 2400 grams. After 12 hours they have done an xray and that shows no change in lungs and again they Asked me to wait for 24 hours for any change. But i discussed with another doctor and changed the hospital immediately. The doctor there put him on ventilator and asked me to give another SURVANTA but 13ml. After 8 hour when they did the xray it shows some changes as lungs are little bit visaible. Now my child is on ventilator and they are providing oxygen pressure 35 which was 100 laSt night. I just want to ask wheather my child will be fine .
