![]() Remember to reset the base line periodically as it changes as the fetus matures. For example, lack of variability, sinusoidal or V-shape waveform, and high/low heart rate are causes for further investigations. Besides the rate itself, how the pattern of rate changes over time is also important. ![]() Instead of trying to interpret the signals yourself, one approach is to establish a baseline and note any deviations from the baseline. Consult your doctor and do not get overly excited if you hear something you do not like. Be patient.įalse-positive is another issue and this is where experience and training come into picture. Since a fetus tends to move around within the womb, locating the fetus heart with the probe can be difficult especially during early pregnancy. For this to work properly, the probe must be in the vicinity of the fetus heart and the bounced signal must be clear enough for the monitor to detect. From this, the fetal doppler can determine where things are inside the body and determines the fetus heart rate. Use the information wisely and understand its limitations.įetal doppler works by sending out a ultrasound wave and detecting the wave that bounces back. This does not mean you should not use a home fetal heart rate monitor, as it does provide useful information and a means to interface with your baby. ![]() Unless you are an expert, do not make any assumptions and always refer to your doctor. Understanding the implication of a certain fetal heart rate pattern requires experience and professional training.
