Tx to decrease preload - -Diuretics -Dilators (nitrates, nitroprusside, morphine) Define preload - -Preload is the volume/pressure in the ventricle at the end of DIASTOLE after the AV valves close, just prior to ejection -As preload increases, SV and CO will increase up to a point -Too high of a preload may lead to heart failure -Preload will seldom be elevate if the heart is without disease and there are no metabolic abnormalities Cardiac output equation - CO = HR x SV Components of str...

Order when reading ABGs? - Oxygenation status (PaO2, level of FiO2 received, O2 delivery device), acid-base balance (pH), ventilation status (PaCO2-also influences acid-base balance), bicarbonate level What are the clinical indications for drawing an ABG? - Patient has a change in LOC, increasing respiratory difficulty, or low blood pressure (or change in BP on arrival). Why do we need to draw an ABG for a patient with low blood pressure? - Because if the body is acidotic and the pH is ver...
