Shock Life-threatening condition in which tissue perfusion is inadequate to deliver oxygen and nutrients to support cellular function -Imbalance in supply and demand for O2 and nutrients -Affects all body systems -May develop rapidly or slowly What are three things good CO should have? Effective pump, adequate vasculature, sufficient blood volume What is the normal level of CO? 4-8 L/min Equation for CO: CO = SV x HR SV is composed of...: -preload -afterload -contractility Cardiacs index eq...

Hemodynamics Practice Questions 100% solved The nurse is caring for a 100-kg patient being monitored with a pulmonary artery catheter. The nurse assesses a blood pressure of 90/60 mm Hg, heart rate 110 beats/min, respirations 36/min, oxygen saturation of 89% on 3 L of oxygen via nasal cannula. Bilateral crackles are audible upon auscultation. Which hemodynamic value requires immediate action by the nurse? a. Cardiac index (CI) of 1.2 L/min/m3 b.Cardiac output (CO) of 4 L/min c.Pulmonary...

Cardiac output equation -:- CO = HR x SV Components of stroke volume -:- Preload Afterload Contractility Preload components -:- CVP (right ventricular) - central venous pressure PAOP (left ventricular) - pulmonary artery occlusive pressure Afterload components -:- PVR (right ventricular) - pulmonary vascular resistance SVR (left ventricular) - systemic vascular resistance 2 | P a g e | G r a d e A + | 2 0 2 4 / 2 0 2 5 Excel! 2 0 2 4 /2025 | © copyright | This work may not...

Cardiac Output (CO) : - Amount of blood pumped through the heart each minute - Normal 4-8 L/min (varies significantly depending on body size) - Determined by stroke volume and heart rate; CO= SV x HR - Cardiac Index is the cardiac output corrected for body size and more specific than CO; use this in obese pts (CI= CO/BSA; Normal 2.4-4 L/min) - Obtained through a pulmonary artery catheter Nursing Assessment of Cardiac Function : Increased Preload= increased volume-blood backs up (right h...

Hemodynamic Monitoring and Assessment What is hemodynamic monitoring and why is this important? - correct answer hemodynamics is the basis of our functioning...it's the processes of the cardiovascular system that allow blood flow to reach end organs hemodynamic compromise like low BP, low fluid status etc. leads to inability to perfuse end organs noninvasive monitoring...head to toe assessment, HR, EKG, PO2 tell us how circulatory system is able to perfuse and oxygenate all the organs ...
