ICU Intervention - CH15 PPT Flashcards
what does capnography measure
end tidal CO2
- important in assessment of ventilation adequacy / respiratory status
what is BP measured with in the ICU
oscillometric device
MAP equation
(0.33) (SBP – DBP) + DBP
what monitoring devices are used for hemodynamic stability in the ICU
pulmonary artery catheters
arterial lines
central venous pressure monitors
what does an arterial catheter monitor
SBP
DBP
MAP
common locations for arterial catheter
radial or femoral artery
what is the common insertion point for venous access
jugular / subclavian vein
femoral can be used, but less common
what does a central venous catheter allow for monitoring of
central venous pressure
or
right arterial pressure
central venous catheters can be helpful in
assessing cardiac function/intravascular fluid
medication/fluid administration
blood sampling
emergency placement of pacemaker
what is a “port”
short-hand for a newport cigarette
nah, it is a central venous catheter implanted under the skin
what can a peripheral venous access be used for
blood draws
total parenteral nutrition administration
normal central venous pressure
2-6 mmHg
importance of CVP monitoring
evaluates right heart function, fluid status and can guide fluid resuscitation
function of a pulmonary artery catheter
measures:
pulmonary artery pressure
cardiac output
mixed venous oxygen saturation
what is the gold standard of temperature measurement
pulmonary artery catheter
how is cerebral perfusion pressure calculated
CPP = MAP - ICP
oxygen delivery systems include
nasal cannulae
high flow nasal cannulae
simple mask
aerosol mask
venturi mask
reservoir mask
tracheostomy collar
what are common airway adjuncts
oropharyngeal
nasopharyngeal
endotracheal tube
what is an oropharyngeal airway
semirigid J shaped tube that fits natural curve of soft palate/tongue
what is a nasopharyngeal airway
tube inserted through one of the nares
what is an endotracheal tube
airway inserted into trachea
normal urine output values
0.5-1.0 mL/kg/hour
normal value of creatinine and BUN
creatinine = 0.6-1.2 mg/dL
BUN = 7-20 mg/dL
