Ask your pediatrician when you should test your baby’s blood pressure. Normally, infants have a low blood pressure. However, if your baby has high blood pressure, you should check it sooner. You should know that an infant’s blood pressure typically increases with age because the heart produces more hormones, resulting in higher blood pressure.
The systolic pressure of an infant typically increases as he grows. At ten days of age, babies who were born at a low gestational age typically had a similar level of blood pressure. There was no significant increase in systolic pressure after conception, which occurred between forty and 48 weeks. The centile position for systolic pressure was not the same as the centile position at three to twelve month of age. Despite these findings, these values can be considered a typical upper limit of systolic blood pressure in an infant.
An infant’s heart muscle is smaller than an adult’s. This means that infants have a faster heart beat. As an infant grows, his heart muscle also becomes more developed and can stretch and contract more efficiently. As a result, the heart does not have to beat as fast to move blood. As the heart gets older, it is easier to expand and contract. This leads to infants having higher blood pressure than adults.
Researchers in the North of England reported that the systolic blood pressure of an infant is higher at birth than at two years of age. In the study, all babies born at 32, 36, and 40 weeks gestation were measured, and the results were compared to those of infants born at these ages. The results were consistent with previous studies and there is no reason for a healthy child to be catheterized.
Hypertension in newborns requires special attention. Although the prevalence of newborn hypertension is very low, the condition is associated with a high risk of developing cardiovascular disease at an early age. Certain causes of newborn hypertension include acute kidney injury and the effects of certain medications. To diagnose hypertension in newborns, the newborn needs to be evaluated and diagnosed as soon as possible. A complete blood count, serum electrolytes and an ECHO cardiogram are the first tests. If the hypertension is caused by an underlying condition, treatment may include oral or intravenous therapy.
An infant’s birth weight has no relation with the diastolic blood pressure of an adult, but it does have a relationship between an infant’s birth weight and the risk of cardiovascular disease. Although the relationship between birth weight and blood pressure remains weak, a small study found that infants born with low birth weights have postnatal growth-accelerated bloodpressure. This may be related to their postnatal adaptations to growth, which may lead to a higher blood pressure.
