A hypertensive crisis is an acute rise of blood pressure that requires urgent medical assessment. The parameters indicating a hypertensive crisis are values above 110 mmHg in diastolic pressure or above 180 mmHg in systolic pressure. Blood pressure figures lower than those stated should still be considered hazardous to health but of lower risk. Hypertensive crises are dangerous as they can trigger damage to the cardiovascular system. In this OneHowTo article we explain what the symptoms of a hypertensive crisis are.

It is possible that during a hypertensive episode there are spontaneous nosebleeds or epistaxis. This is due to the high pressure conditions in which the blood is forced to flow through the arteries. Nosebleeds may also be accompanied by a persistent ringing in the ears, known as tinnitus, which can be distressing and disorienting for the patient.
