Hypertensive Urgency vs Emergrncy

-Urgency: is increase in BP > 180 / 120 w/o any signs of target organ damage
-while emergency: is increase in BP > 180/120 w s/o target organ damage , like:


  1. Flash pulm edema- do CXR
  2. CVA: get CTB
  3. renal failure: get BUN and Cr
  4. Coronary ischemia/ infarction: get EKG and Cardiac Enzymes
Management:
 for Urgency:: goal is to decrease BP by 25% in next 24 hrs
While for Emergency : goal is to decrease BP by 10% in next 1 hr and 25 in next 3- 4 hrs

Pathophysiology:

High BP--cause damage to endothelium---> Decrease NO secretion---> further exacerbates BP
Also Due to Endothelin damage ---> there will be Capillary leakage --> causing Flash Pulm Edema

Hypoxemia

If pt is getting Hypoxemia---> give High FiO2---> improving then
 does not improve---> increase PEEP: 

Pressors


  1. Septic Shock: use Either Dopa or Levophed---> if u started with either of them then next of choice is Vasopressin--> if still low then add the one that u did not use before ( from Dopa or Levophed)
  2. Anaphylactic Shock: Epinephrine
  3. BP is low but stable, Heart failure and Pt is getting Acute pulmonary Edema / or other organ failure 2/2 Cardiogenic SHock then use Dobutamine
