Movement of blood is pretty much the sole responsibility of thecirculatory system.
It means that unless healthcare providers do something, the process is unstable and in danger of failing.
Some common synonyms for hemodynamic instability includecirculatory collapse,shock(especiallydecompensating shock),hypoperfusion, andcardiovascular failure.

In addition, some terms describe causes of hemodynamic instability while also acting as synonyms, such ashypovolemiaandhypotension.
It’s important to understand that not generating enough pressure isnotthe same thing as being able to measurelowblood pressure.
Signs
This doesn’t happen alone.
People don’t just become hemodynamically unstable for no reason.
Physicians, as a group, tend to have a pretty strong grasp on those nuances.
This is the physiological mechanism that the human body invokes when it feels as if it is threatened.
The idea is that the body is preparing to either fight or run from a predator.
The fight or flight syndrome is mostly about circulation.
Notice that nothing in here requires a low blood pressure.
The other two have to do with being emotionally overwhelmed or with electricity.
Shock is a medical condition with definedtypesand levels, unlike hemodynamic instability.
It could be said that decompensated shock is a hemodynamically unstable shock patient.
It means to fill with blood and is often used specifically to refer to blood filling the capillaries.
Capillaries are basically passive channels where red blood cells can enter only in single file.
This is a result of hemodynamic instability but is synonymous with shock.
In fact, the terms shock and hypoperfusion are completely interchangeable.
