What are the signs of a healthy fetus

From conception until the 10th week of your pregnancy, your baby is an embryo, according to the website of the Medical Center of the University of Maryland. It becomes a fetus at the end of the 10th week. During the embryonic period, when the baby is experiencing rapid cell growth and development, it has more risk of interference from external to their health and development threats. Once entering the fetal period, fetal behavior is the sign of health, but doctors usually do routine tests and tests to determine the health of the baby.

Movement
About 5 months of pregnancy, your baby will begin to move. The first fetal movement is called acceleration, according to the Cleveland Clinic. A 6-month fetus reacts to sounds with movements, unstable movements can be a sign that hiccups. Around the 7th month, responds to stimuli such as pain, sound and light. Your baby changes positions often and 8th month kicks more frequently. At 9 months it moves less because he has a lot of room. It may be that your doctor will ask you to take control of fetal movements you experience, counting kicks and reporting changes.

Normal growth and development
It may be that your doctor will do certain routine tests to determine fetal development. An ultrasound helps you to see your baby and assess growth. According to the website of the Medical Center of the University of Maryland, a healthy 5-month fetus measures about 10 inches (25 cm). If it grows 2 inches a month, in the month 7 measured 14 inches (30 cm). Between weeks 29 and 30, or in the third quarter, a healthy fetus grows about 1/2 ounce (15 g) per week. For the ninth month your healthy fetus will weigh about 7 pounds (3.2 kg) and measure 18 to 20 inches (45-50 cm).

healthy heartbeat
Electronic fetal monitoring is used to control the heartbeat of the fetus during pregnancy, according to the Congress of Obstetricians and Gynecologists in the United States. Examination of the non-stress and stress of contractions allow your doctor to look for potential problems and confirm heart health of your baby. During delivery the heartbeat of the fetus, to be maintained at a rate of between 110 and 160 beats per minute is also monitored.

Pre-natal slump
Even though your baby is moving less during the 9th month, it is during this period that changes the position to prepare for childbirth. According to the Cleveland Clinic, the fetus down to your pelvis and head pointing toward the birth canal.


Pattern of respiratory movements in the healthy fetus with normal growth
A descriptive model of cross-sectional variable studied by Doppler color technology through time series analysis and the theory of dynamical systems was addressed. The population consists of pregnant and sample audio signals 30 patients who met the inclusion criteria. These were acquired with an ultrasound-Doppler color Brand APOGEE 800 PLUS with 3.5 MHz convex transducer which collected the analog audio signal through a BNC connection RCA audio output and video delequipo stored on personal computer under Windows using Adobe Systems, Audacity software, which allowed export the audio data to numeric data and apply mathematical analysis. For nonlinear analysis data were processed with FDM packages, Rtisean and tseriesChaos under R. Obtained correlation dimension (DC) programming, the sample was divided into 2 groups: premature pregnancies with fetuses (32-36 weeks) and term (37 to 38 weeks). The Χ ± SD of the DC term fetuses was = 0, 71 ± 0.06 DS and premature group DS 0.73 ± 0.06 with a test t = - 2.304 and P value <0.023 * statistically significant. It is concluded that the identification of patterns during pregnancy MRF includes a variability and complexity of the behavior of a dynamical system.

The decrease in perinatal mortality to 12 per 1,000 in most centers in relation to the last decade is due to the application of specific techniques for fetal assessment. Thus, through high-resolution ultrasound it has become increasingly possible not only accurate diagnosis of acute and chronic fetal asphyxia but health (1).

This has been studied various biophysical variables fetal indicators of fetal well as fetal tone, spontaneous fetal movements, the amount of amniotic fluid, the presence of fetal breathing movements (MRF) described by Manning in the fetal biophysical profile (2) and aortocaval (2: 1) relationship proposed by Dr. Inaudy Bolivar in 1983, which states that under normal conditions the diameter of the aorta is usually almost twice the inferior vena cava and the latter collapses during fetal breathing movements (3).

The human fetus has more or less rhythmic breathing movements episodes, interspersed with longer periods of apnea. These fetal breathing movements are part of the study parameters of different biophysical profiles designed to assess fetal well-being, and constitute one of the variables that determine the different stages of fetal behavior, along with heart rate and body movements and eye ...
