A child born between the 38th week of pregnancy and the 42nd week was born full term.
If a baby is born before 37 weeks of pregnancy it is classed as premature.
It is around 22 - 24 weeks of pregnancy that a fetus is considered viable.
Babies born between 33 weeks and 37 weeks of pregnancy are more common and have excellent prognosis.
Between 32 and 34 weeks is the time at which the babies lungs mature, therefore these babies may require help with their breathing by means of a ventilator.
Approximately 7,000 children, are born between 27 and 33 weeks of pregnancy and will certainly require ventilation and care in a special baby care unit.
For babies born before 27 weeks of pregnancy there is a 50% risk of mortality and they can have significant problems
The number of babies born prematurely has steadily increased over the last few decades, with assisted conception and multiple pregnancies being more prominent.
