General diagnosis of shock

Blood pressure should be measured during shock.

In order to determine a shock (diagnosis of shock), a clinical examination is first of all necessary. Here are:

  • Responsiveness
  • Blood pressure
  • Pulse
  • breathing
  • Skin color
  • temperature
  • excretion (through the kidneys)

In case of shock, the Blood pressure low, pulse fast, skin color is usually pale, breathing accelerates and urine stops being produced. Furthermore, during the diagnosis it can be asked whether the patient is known Allergies has ingested toxic substances or has had an accident

Special investigation

Assessing the color of the Gums or a Pressure test on the Fingernail (after letting go, it takes approx. 1 second until a rosy color can be seen again in the healthy patient) already allow first assumptions about the patient's blood flow.
These assumptions can now be supported by a Blood test be supported. Here one examines among other things:

  • the Hemoglobin content (Hemoglobin is found in red blood cells) of the blood
  • the percentage of all blood cells (hematocrit)
  • the coagulation factors (if too few are present, there may be internal bleeding)
  • the number of leukocytes, which are greatly increased in a bacterial infection.

Device-based diagnosis

The Measurement of central venous pressure (CVP) lets the distinction between Volume depletion and cardiogenic shock to. In the case of volume deficiency shock, this is reduced, in the case of cardiogenic shock, it is increased due to the back pressure in the venous system.

A EKG (electrocardiogram) provides information about the status and function of the Heart and is part of the basic diagnosis of suspected cardiogenic shock. If this is suspected, a right heart catheter can also be inserted to examine the pressure in the left atrium. A pressure sensor is inserted through the inguinal artery.
