What are signs and symptons of shock?

There are several different types of shock. They are Anaphylactic, Cardiogenic, Hypovolemic, Respiratory Insufficency, Neurogenic, Psychogenic (fainting),and Septic. I am training to be an EMT and we learned to assess the general signs of compensated shock as: Agitation, Anxiety, Restlessness, Feeling of Impending Doom, Altered Mental Status Weak, Rapid (thready) or absent Distal Pulses Clammy (pale, cool, moist) Skin Pallor (paleness) with Cyanosis (blue color) of the Lips Shallow, Rapid Breathing Air Hunger (shortness of breath), especially if there is a chest injury Nausea or Vomiting Capillary refill of longer than 2 seconds in infants and children Marked Thirst DECOMPENSTAED SHOCK (later stage) is when the blood pressure begins to fall and patients soon move into IRREVERSIBLE SHOCK in which no interventions or transfusions will reverse the effects and death is imminent. The best option is to treat people once the first signs of compenstated shock develop and to seek medical treatment ASAP. PLEASE KEEP IN MIND THE VERY FIRST SIGN OF COMPENSTATED SHOCK IS AGITATION OR ALTERED MENTAL STATUS. Every type of shock is triggered differently, presents differently, and needs to be treated differently. However rapid transport, maintaining an airway, controlling bleeding, thermal management (keep them warm), and elevation of the legs so long as no spinal injuries are suspected seem to be a key theme. The signs of DECOMPENSTATED SHOCK are as follows: Falling Blood pressure (systolic blood pressure of 90 mm Hg or lower in an adult) Labored or irregular breathing Ashen, mottled, or cyanotic skin Thready or absent pulses Dull eyes, dialated pupils Poor urinary output. Hope this was able to help! :)
