For many elderly people at risk of hypertension, mercury sphygmomanometer is a must-have at home. Besides measuring blood pressure, mercury sphygmomanometer can also be used to prevent stroke. The principle of using mercury sphygmomanometer to prevent and treat stroke is called remote ischemic preconditioning. This therapy is not only effective before severe ischemia, but also can reduce injury and improve prognosis during and after severe ischemia.

The method is that the patient takes the supine position or semi-sitting position, with both upper limbs at the same height as the heart, wraps the cuff of the mercury sphygmomanometer around the middle and upper part of one upper arm, pressurizes the airbag to 180-220mmhg, keeps it for 5 minutes, then releases the airbag pressure and rests for 5 minutes. Repeat for 5 rounds, ***50 minutes, twice a day. It is suggested that every morning and evening 1 time, the upper limbs alternate, and 6 months is a course of treatment.

It is particularly important to know the severity of stroke and to prevent and treat it at an early stage. Knowing the risk factors of stroke and giving certain intervention and treatment can prevent and reduce the occurrence of stroke and reduce the disability rate and mortality rate.

Primary prevention

"If an individual only has one or more of the above risk factors and has no signs or manifestations of cerebrovascular disease, we will list it as a primary prevention goal, that is, actively treat the existing risk factors, and regularly monitor the occurrence of other risk factors and take targeted measures.

Secondary prevention

Early diagnosis and treatment are given to individuals with existing risk factors and stroke precursors (such as transient ischemic attack) to prevent the occurrence of serious cerebrovascular diseases, which is secondary prevention.

Tertiary prevention

For patients who have already suffered from stroke, early or ultra-early treatment can reduce the degree of disability, remove or treat risk factors, and avoid being prevented by tertiary prevention. The so-called early treatment refers to the treatment of patients in acute phase after a few hours of onset, and the so-called ultra-early treatment refers to the treatment implemented within a few hours of onset. For example, for ischemic stroke, thrombolytic therapy should be started within 6 hours after onset, and the earlier targeted treatment measures are taken, the better the treatment effect and the lower the degree of disability.
