Intro Flashcards
closed vs open ICU model
Closed-ICU docs only
Open-allows diff members of staff to work in ICU
nursing ratio in ICU
usually 1:1
nursing ratio in SDU or PCU
usually 2:1 or 3:1
MC reason for ICU admission
Hemodynamic Monitoring
goal pulse ox
92-94% SpO2
( ) is an accurate reflection of O2 in arterial blood
P02
C/I for arterial cannulation
Positive Allen test (radial)
Coagulopathy
Severe vascular disease
Previous vascular surgery
where to place a central line
Internal jugular vein
Subclavian vein
Femoral vein
Pulmonary Artery Occlusion Pressure (PAOP) =
left ventricular end diastolic volume
cardiac output =
stroke volume x HR
normal 4-6 liters/min
stroke volume =
end diastolic volume - end systolic volume
ejection fraction =
(SV/EDV)x100
flotrac
attaches to existing a-line and measures stroke volume variation (SVV), a waveform analysis of change in amount of volume in ventricle during different contractions
NICOM
a non-invasive cardiac output device measuring changes in impedance in the chest thus deriving CO.
cerebral perfusion pressure =
MAP - ICP
pressure of blood flowing to brain
