okay, so Shock is a rapid loss in blood pressure, meaning the body is less able to pump oxygen (via blood in arteries) to all it's necessary organs.
Hypovolemic shock is particularly where the blood pressure loss is caused by rapid blood or fluid loss in the body. This may be caused by dehydration or internal/external bleeding. So basically the body's organs aren't receiving enough blood/oxygen.
The weak pulse is basically a physical indicator that the body has a low systolic blood pressure. Now, since the weak pulse provides less oxygen to the body, the body needs to come up with a logical way to push more oxygen into the body systems. The only way to do this would be to increase the heart rate so to even out the fact the blood pressure is low. Hence, you end up with a rapid but weak pulse.
Hope this Helps :)
early sign of hypovolemic shock
Early signs of hypovolemic shock include rapid heart rate, low blood pressure, pale or cool skin, rapid breathing, and feeling weak or dizzy. It is important to seek medical attention immediately if these symptoms are present.
a type of hypovolemic shock
Hypovolemic shock is primarily caused by poor perfusion, usually from excess blood or fluid loss from the body. Hypovolemic shock is the most common type of pre-hospital shock often resulting from moderate or severe trauma.
Cardiogenic, hypovolemic, or septic shock?
Signs of traumatic shock include weak and rapid pulse, shallow and rapid breathing, and pale, cool, clammy skin
Shock
only that form of shock caused by large scale loss of blood.
cardiovascular
Signs of shock include pale, clammy skin, rapid and shallow breathing, weak and rapid pulse, and confusion or dizziness. Shock is a serious condition that requires immediate medical attention.
The pulse is rapid and may be to faint to be felt in the wrist.J-Ray
