Traumatic injury
Serious injury to the body, as from physical violence or an accident
Psychological trauma
Severe emotional or mental distress caused by an experience
Arterial Blood Gases
An ABG is a blood test that measures the acidity, or pH, and the levels of oxygen (O2)
and carbon dioxide (CO2) and HCO3 from an artery

Arterial Blood Gases include
PH & PO2 & PCO2 & HCO3
BE
Base Excess or Base Deficit
Fibrinogen
Level of Fibrinogen
One of the Coagulating factor of blood
