Treatment options for cardiogenic pulmonary edema: --ANSWER---Morphine
-Furosemide (Lasix)
-Increase O2 if hypoxic
How can SvO2 be measured? --ANSWER---Pulmonary artery catheter w/ a built in reflective
pulse oximeter.
-Current technology does not allow us to insert a separate line within the normal 4-lumen
catheter or to insert a line in addition to the pulmonary artery line
-if normal 4 lumen catheter is in place it will be necessary to replace the current catheter w/
one that has this specific capability
What is SVRI? --ANSWER---systemic vascular resistance index
-The physiological meaning of SVRI is the tension or pressure that builds up in the wall of
the left ventricle during ejection.
Equation for SVRI: --ANSWER--(MAP-CVP)/CI
SVRI normal --ANSWER--1970-2390 dynes .sec/cm5/m2
MAP normal --ANSWER---mean arterial pressure)
Page 1 of 109
,-93-94 mmhg
MAP equation --ANSWER--determined by taking the systolic pressure, adding the diastolic
pressure twice, and dividing by the number 3 (heart spends twice as much time in diastole
than in systole)
cardiac What values does the pulmonary artery catheter measure? --ANSWER--PAP
Capabilities of the pulmonary artery catheter: --ANSWER---cardiac output
-pressures in the right side of the heart and in the arteries of the lungs
How will positive pressure ventilation affect the the reading of a pulmonary artery catheter? -
-ANSWER---decrease cardiac output
-Positive pressure ventilation increases intrathoracic pressure (ITP), which increases right
atrial (RA) pressure, leading to a decrease in venous return. Subsequently, this decreased
right ventricle (RV) filling decreases left ventricle (LV) preload and allows for greater LV
contraction with decreased energy expenditure. In patients who are volume overloaded, this
could be beneficial. However, in hypovolemic patients, this may induce cardiovascular
insufficiency [2, 3]. Therefore, knowledge of the volume status of mechanically ventilated
patients is essential. On critically ill patients, pulmonary artery catheters (PACs) can be used
for hemodynamic monitoring
How do you determine the integrity of a pulmonary artery catheter? --ANSWER---CXR will
confirm position
Page 2 of 109
,Elevated PCWP and mPAP can indicate: --ANSWER--left heart failure (CHF) w/ pulmonary
edema
Spiked T waves can indicate: --ANSWER--possible electrolyte imbalance
Is PCWP usually elevated with ARDS? --ANSWER--No
With acute Cor Pulmonale (right heart failure) will CVP increase or decrese? --ANSWER--
significantly increase
If patient is hypervolemic ___ will be elevated --ANSWER--CVP
CI normal --ANSWER---cardiac index
-2.5-4.0L/min/m2
CI equation --ANSWER--cardiac output/body surface area (BSA)
Normal PCWP means ___ is working well --ANSWER--left heart
Elevated mPAP and CVP indicate the problem is in the ____________ --ANSWER--lungs
and backing up into the right heart
Normal cardiac index = --ANSWER--good left heart function
Page 3 of 109
, Normal PCWP = --ANSWER--good left heart function
Mildly elevated PVR = --ANSWER--lung trouble
Sudden fall in PECO2 with a wide disparity b/w that value and the PaCO2 is a very strong
indicator of an increased alveolar deadspace caused by a pulmonary embolism and the
hemodynamic values are consistent with an circulatory obstruction in the lungs sim 2 --
ANSWER--
A _______ ______ will suddenly block perfusion to an area of the lungs and cause alveolar
deadspace ventilation. This causes the exhaled CO2 to drop while the arterial CO2 remains
stable --ANSWER--pulmonary embolism
Administration of t-PA is for --ANSWER---potential tx for PE but very expensive and
premature to administer for initial tx
Administration of warfarin (Coumadin) is for --ANSWER---potential PE tx, takes time to
build up in the blood stream and could be recommended when pt is ready to go home
Administration of streptokinase is for --ANSWER---potential tx for PE but very expensive
and premature to administer for initial tx
Administration of IV heparin is for --ANSWER---standard initial treatment for pulmonary
emboli
-quickly reduces the possibility of further clots from forming and causing additional emboli
