Obstructive Shock: Causes, Signs and Symptoms, & First Aid Management. Obstructive shock is a medical emergency that occurs due to mechanical problems that averts diastolic filling resulting to decreased cardiac output. Obstructive shock is a medical emergency that occurs to mechanical problems that avoids diastolic filling from occurring.
Shock 3 Distributive shock is usually caused by an acute insult, e.g. spinal trauma or anaphylaxis, and presents with profound hypotension and tachycardia. Obstructive shock is due to increased afterload of the right ventricle (saddle embolus) or left ventricle (critical coarctation).Patients often present with signs / symptoms similar to Cardiogenic shock â tachycardia, tachypnea, hypotension, decreased mental status, and poor urine output. Low mixed venous oxygen saturation (defined below) is a hallmark of uncompensated shock. Mixed venous oxygen saturation [MvO 2 ] is a measure of the oxygen extraction by peripheral tissue. A low MvO 2 indicates inadequate oxygen delivery, increased oxygen consumption or both.
