That's because your major artery collapses from the pressure.
I cant get areading
That reading would indicate a high blood pressure, 120 over 80 would normal.
blood pessure
blood pressure and your heart would be healthy
at abnormally elevated blood pressure
This would be within the normal range for an adult diastolic resting blood pressure.
Systole is the top number of a blood pressure reading. It is the heart contracting forcing blood out. Indicated by the first heart sound. Diastole is the bottom number of a blood pressure reading. It is the heart relaxing bringing blood back in.
Blood pressure would decrease
High blood pressure is measured as two numbers, systolic pressure over diastolic pressure. Any reading of 140/90 or higher is considered high blood pressure.
A blood pressure reading of 70 over 38 means that the systolic pressure is 70 mm Hg and that the diastolic pressure is 38 mm Hg. Systolic pressure is the maximum pressure present in an artery during contractions of the heart due to blood being pumped through the arteries. Diastolic pressure is the lowest pressure present in an artery prior to another contraction by the heart and more blood being pumped through the artery. Now, most normal blood pressures fall in the range of 90/60 to 130/80. A blood pressure reading of 70/38 means the person having their blood pressure checked has hypotension, or low blood pressure. This means the heart, brain, and other parts of the body are most likely not getting enough blood, and there appears to be something wrong with the body. What is exactly is wrong would be up to a doctor to diagnose, as there are several factors that could lead to low blood pressure.
