The Non Stress Test (NST) is a nonintrusive checking of baby’s heartbeat and movements. The NST convinces whether the baby is getting adequate oxygenation . The present study titled “Outcome of Fetal Parameters In Left Lateral Position During Non Stress Test”was aimed to identify the selected fetal parameters during Non Stress Test in Left Lateral Position and to ascertain the comfort of Antenatal mothers in Left Lateral Position during the Non Stress Test. A descriptive design with a convenient sampling of 100 samples were placed in left lateral position during Non Stress Test. Antenatal mothers who fulfill the sample inclusion criteria were selected for the study. The demographic variables and clinical data / maternal baseline characteristics were collected by interview of mothers and from medical records. The fetal parameters were assessed by observation and recording of biophysiological measurements from Non Stress Test tracing and Comfort of maternal positions were assessed by Verbal Numerical Rating Scale. The result reveals that 32% of prenatal women shows a baseline FHR of 140-149 BPM and 84% with a beat to beat variability of 5- 15 beats per minute. There was 3 to 4 acceleration in 78% of subjects and only 35% shows more than one deceleration. Majority (89%) perceived 2 to 4 fetal movements during NST. Among the sample, 44% of prenatal women verbalized they were very comfortable in left lateral position and 30% verbalized full comfort during NST procedure.The study concludes that left lateral position provides good reactivity during NST and mothers expressed left lateral position as a comfortable position for the procedure.
