vital signs

Key health indicators

Maintaining our health is an ancestral universal need. Over time human beings have learned to access and understand signs that indicate when vital functions are altered, i.e., our vital signs.

With the latter we make decisions that keep us from getting sick or cure us from a diseases, expanding our ability to live longer and better.

learn more about icp

what is icp?

Intracranial pressure (ICP) represents the relationship between altered skull volume and the ability of the intracranial axis system to accommodate such volume. the principles of intracranial pressure (ICP) were described by monro and kellie in the 1820s. They noted that, in adults, the brain is enclosed in a skeletal structure and that the volume present therein must remain constant so that the icp also remains constant.

The total volume inside the skull is calculated by the sum of the compartments of cerebrospinal fluid, blood and brain tissue. cerebral blood flow is constantly maintained by self-regulating mechanisms, so when a volume is added to the system or there is a pathological component, the compensatory mechanisms (e.g., the displacement of cerebrospinal fluid into the subarachnoid space of the spine and reduction of cerebral intravascular volume) operate to maintain icp constant. the current values ​​of normality are between 3 and 22 mmhg.
