Hemodynamics Lecture Flashcards
Arterial line
-measures
Blood pressure
- measures ABGs
- pressure bag at 300
Central venous catheter
-measures
Central venous pressure (CVP)
-ScvO2 (Central venous oxygen saturation)
Pulmonary Artery Catheter
-measures
- CO
- Pulmonary arterial pressure
- PAOP (wedge)
- CVP
- ScvO2
Intraventricular Catheter
-measures
-ICP: drains fluid from the brain
Arterial Line (A-line) -Mean Arterial Pressure (MAP) normal values
- normal= 70-100
- mean of >60 needed to perfuse organs
Arterial Line (A-line) -Mean Arterial Pressure (MAP) calculations
( 2 x diastolic ) + systolic / 3
Arterial Line:
-what NOT to infuse in it
MEDICATIONS
advantages of an arterial waveform vs EKG
arterial waveform shows dicrotic notch and appropriate wavefrom even if EKG is irregular
Significance of dicrotic notch
closure or the semilunar valves
Central venous Catheter
-where does it measure CVP
right atrium
Central venous Catheter
-normal values
2-5
8-10 if on ventilator
Central venous catheter
- what does it indicate of the patient
- what can be given in this line
- fluid balance of the patient
- Meds and fluids
Central venous Pressure
-where/what is it measured
Preload pressure of the right atrium and ventricle
-can only be accessed by a CENTRAL line
Indications for monitoring CVP
- critically ill patients
- fluid/ volume status
- sepsis
- shock
- MI
- those on vasoactive meds
Pulmonary Artery Catheter (PA-line)
- Deflated balloon measurement
- inflated balloon measurement
- Pulmonary artery pressure
- PAOP pressure or Left ventricular at end diastolic pressure (LVEDP)
