Advanced Hemodynamic Monitoring Flashcards
normal cardiac index value (CI)
2.2-4.2 L/min/m2
normal central venous pressure value
5-12 mmHg
CVP is most accurate when measured at the end of (inspiration/expiration)
expiration
what position are CVP, PAP, and PWCP readings considered reliable?
if the backrest positions are from 0-60 degrees
-not considered as accurate if the patient is truly “sitting”
normal value of coronary perfusion pressure
auto regulated between 50-120 mmHg
normal value of mixed venous oxygen saturation (mvO2)
60-80% in an awake patient
mixed venous oxygen saturation is roughly equal to what other value?
central venous oxygen saturation (ScvO2)
normal value of pulmonary artery pressure
15-30
——— mmHg
10
pulmonary artery pressure is not considered “accurate” if the patient is in what position
sitting
-same reason as CVP
value of mild pulmonary hypertension
36-49 mmHg systolic
value of moderate pulmonary hypertension
50-59 mmHg systolic
value of severe pulmonary hypertension
> 60 mmHg
normal value of pulmonary capillary wedge pressure (PCWP)
less than 12 mmHg
1-4 mmHg less than pulmonary artery diastolic pressure
PCWP is not considered accurate if the patient is in what position?
sitting
-same reasons as CVP
normal value for pulmonary vascular resistance (PVR)
100-300 dynes:sec:cm-5
normal value for an adult stroke volume
60-90 mL/ beat
normal value for stroke volume index
20-65 mL/beat/m2
normal values of systemic vascular resistance (SVR)
700-1200 dynes:sec:cm-5
normal values of central venous O2 saturation (ScvO2)
25-30% below the patients SaO2
OR
70-75% if the SaO2 is normal
which reflex responds to a changes in blood pressure?
baroreceptor reflex
where are the baroreceptor reflexes located?
inside the carotid sinus (hypoglossal nerve)
and aortic arch (vagus nerve)
Baroreceptor reflex: when the blood pressure is low, the HR (increases/ decreases)
increases
Baroreceptor reflex: when the blood pressure is high, the HR (increases/ decreases)
decreases
which reflex responds to changes in blood volume inside the heart
bainbridge reflex
