A high pressure of 78 and a low pressure of 54 generally means a systolic pressure of 78mmHg and a diastolic pressure of 54mmHg, which is not normal. Blood pressure is the blood flow in the blood vessels on the blood vessel wall pressure, can be divided into systolic and diastolic blood pressure, systolic blood pressure is also commonly referred to as high pressure, the normal range of values between 90mmHg to 139mmHg, diastolic blood pressure is also commonly referred to as low pressure, the normal range of values between 60mmHg to 89mmHg, while the patient’s systolic blood pressure is 78mmHg, diastolic blood pressure is 54mmHg, diastolic blood pressure is a little low, so it is not normal. The patient’s systolic blood pressure is 78mmHg and diastolic blood pressure is 54mmHg, the diastolic blood pressure is a bit low, so it is not normal. If the patient maintains low diastolic blood pressure for a long time, there may be dizziness, generalized weakness, panic because of insufficient irrigation of peripheral organs, and in serious cases, fainting and even shock may occur, so timely treatment is needed to avoid delaying the best treatment time.
