It is called "nonstress" because doing it places no stress on the fetus.</p> <h3>Why Are Nonstress Tests Done?</h3> <p>A nonstress test (NST) is usually done when a health care provider wants to check on the health of the fetus, such as in a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/high-risk.html/">high-risk pregnancy</a> or when the due date has passed.</p> <p>The test checks to see if the baby responds normally to stimulation and is getting enough oxygen. A baby that doesn't respond isn't necessarily in danger, though <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/prenatal-contraction-stress.html/">more testing</a> might be needed.</p> <p>Sometimes, a biophysical profile (BPP) is done, which includes an ultrasound and an NST. A BPP examines a baby's breathing, movement, amount of amniotic fluid, and tone, in addition to the heart rate response.</p> <h3>Should I Have a Nonstress Test?</h3> <p>Your health care provider may recommend this if you have a high-risk pregnancy, if there are concerns during your pregnancy, or if you have a low-risk pregnancy but are <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/due-date.html/">past your due date</a>.</p> <h3>What Happens During a Nonstress Test?</h3> <p>You'll wear two monitors (one tracks the baby's heartbeat and movement, and the other records contractions) while lying on&nbsp;<span style="font-size: 1em;">your left side. A technician monitors the fetal heart rate&nbsp;</span>during each movement&nbsp;<span style="font-size: 1em;">on a screen while your contractions are recorded on paper.</span></p> <p>If there's no movement during the test, the baby may be asleep and the technician may use a buzzer to wake the baby. You also may be asked to drink or eat to try to stimulate the baby more.</p> <h3>When Are Nonstress Tests Done?</h3> <p>A nonstress test is done any time after 26 to 28 weeks, depending on why it's needed. This is the age when a baby's heart rate can respond to movements by speeding up or slowing down.</p> <h3>When Are the Results Available?</h3> <p>Results of a nonstress test are ready immediately.</p>Examen prenatal: Examen sin estrésUn examen sin estrés controla el ritmo cardíaco de un bebé aún no nacido durante 20 a 30 minutos para ver si cambia cuando el feto se mueve o durante las contracciones. Recibe el nombre "sin estrés" porque el examen no provoca ningún tipo de estrés al feto.https://kidshealth.org/ws/RadyChildrens/es/parents/prenatal-nonstress-esp.html/2c30f9b5-7bc5-4910-aaeb-9b617b70bb0f
