Cvicu Test

NU1426 SMART PASS SOLUTIONS. CVICU test 60 for COPD pt PaCO2: 35-45 (acidic= 45, alkalotic= 35) HCO3: 22-26 (high alkalotic, low acidic) cardiac output - Answer-The volume of blood ejected from the left side of the heart in one minute. Stroke volume x heart rate 4-8L/min is normal high CO - Answer-hyperdynamic states: pregnant, sepsis, hyperthyroid crisis low CO - Answer-inadequate filling: arrhythmias, hypovolemia, cardiac tamponade, valve stenosis (hardening), diastolic dysfunction inadequate ejection: MI, valve insufficiency (leak), increased afterload, negative inotropic drugs Cardiac Index (CI) - Answer-*2.5-4 L/min/m2* - CO divided by the body surface area. The cardiac index *adjusts the CO to body size* Stroke Volume (SV) - Answer-amount of ejected blood each beat 60-100 mL per beatNU1426 SMART PASS SOLUTIONS. Low SV - Answer-inadequate preload, increased afterload, valve dysfunction, impaired contractions of the heart High SV - Answer-sepsis, vasodilators, anaphylaxis preload - Answer-blood volume in the ventricles while resting (pushing the rubber band) CVP - Answer-right ventricular preload 2-6mmHg CTS likes the CVP to be 8-12 it is a pressure value bc it is the amount of volume pressing on the right heart high CVP - Answer--greater than 6 -indicates an elevated right ventricular preload -fluid overload, cardiac
