SERUM LACTATE
0.6-1.5
noninvasive hemodynamic monitoring methods
- BP
- JVP
- SERUM LACTATE
invasive hemodynamic monitoring methods
- arterial pressure monitoring
- pulmonary artery pressure monitoring
- right atrial pressure monitoring (aka CVP monitoring)
indications for invasive arterial pressure monitoring
-those who are hemodynamically unstable, in need of frequent lab work, and being managed with vasoactive agents
sites for arterial pressure monitoring
radial site (allen test) femoral site can use brachial arteries also or other smaller ones but they're avoided unless other access is unavailable
minimum MAP to perfuse coronary arteries
> 60
ideal MAP for cardiac patient to decrease LV workload
70-90
MAP that may be necessary after carotid endarterectomy and neurosurgery and the MAP that increases cerebral perfusion pressure
90-110
indications for CVP monitoring
pt with significant alteration in fluid volume (CVP helps guide fluid volume replacement in hypovolemia) and to assess the impact of diuresis after diuretic administration in the case of fluid overload
insertion sites for CVCs and their considerations
- internal jugular vein: high infection rate
- subclavian vein: preferred if longer than 5 days, possibility for pneumothorax and phrenic nerve damage
- femoral vein: good for CRRT and plasmaphresis; possibility for mobility restriction, high infection rate
complications of CVP monitoring
CHIPDAT
- carotid puncture
- heart perforation
- infection
- pneumothorax/hemothorax
- dysrhythmias
- air embolism
- thrombus formation
patient position for CVP monitoring
HOB 0-60 degrees
