2.Non Stress Test
Non stress Test or NST
What do we mean by that ?
Non stress test is done during pregnancy or the third trimester in pregnant women .
To check the fetal heart rate or the fetal well-being or the o2 supply in the fetus ,
It is usually done for 20 to 30 mins of duration , it can be done more than twice a week .
Non stress test can be divided into two types :
One is reactive non stress test and the other one is non reactive non stress test .
In reactive non stress test there will be acceleration for two or more times .
Here acceleration means , 15 beats per minute in 15 seconds .
And in case of non reactive non stress test ,
There will be no acceleration within 20 minutes and the beats will be less than 15 beats per minute .
In case of reactive non stress test, that’s normal and it means the fetus is having proper oxygen or blood supply
Therefore the reactive non stress test indicates that the fetus is having proper oxygen supply and blood supply .
The normal fetal heart rate is 130 to 150 beats per minute .
So this is what non stress test is ,Thank you !
