Question 3

What are Special Considerations in trauma patients

Accepted Answer

Age \> 55 yrs old Systolic BP \< 110mmHg in age \> 65yrs old Use of anticoagulants Pregnancy Burns with trauma

Question 4

Oxygen Dissisociation Curve

Accepted Answer

Affinity of oxygen on hemoglobin and oxygen in plasma Spo2 and PaCo2 -too much fluid can transfer oxygen from hemoglobin to a larger plasma if there is more fluid cause an increase in paco2 and decrease in spo2 -temperature also effects (sweet tea) and how molecules dissolve -pH also effects trauma by decreasing chance of transporting oxygen

Question 5
