Hemodynamics for Nurses Course

Lesson 1 • Coronary and Pulmonary Circulation

Distinguishes systemic, pulmonary, and coronary circuits. Connects circuit anatomy to oxygenation and perfusion concepts used in hemodynamic monitoring.

Lesson 2 • Cardiac Conduction System

Maps the electrical pathway from sinoatrial node to Purkinje fibers. Establishes how conduction timing governs mechanical contraction and cardiac output.

Lesson 3 • Heart Chambers and Valves

Covers atrial and ventricular anatomy plus valve function. Provides the structural baseline for understanding pressure generation and flow direction.

Lesson 1 • Frank-Starling Mechanism

Explains length-tension relationship in myocardial fibers. Nurses apply this concept to fluid responsiveness decisions and volume management strategies.

Lesson 2 • Oxygen Delivery and Consumption

Quantifies oxygen delivery as cardiac output times arterial oxygen content. Nurses use this relationship to prioritize interventions in low-perfusion states.

Lesson 3 • Cardiac Output Determinants

Defines cardiac output as the product of heart rate and stroke volume. Each determinant is linked to clinical interventions nurses perform or anticipate.

Lesson 4 • Pressure, Flow, and Resistance Relationships

Introduces Ohm's law analog applied to circulation. Nurses use this framework to predict how resistance changes alter flow and perfusion pressure.

Lesson 1 • Alarm Management and Safety

Establishes evidence-based alarm threshold setting and response protocols. Nurses reduce alarm fatigue while maintaining patient safety in monitored environments.

Lesson 2 • Noninvasive and Minimally Invasive Monitors

Surveys pulse oximetry, noninvasive blood pressure, and pulse contour analysis devices. Nurses select appropriate monitoring modality based on patient acuity.

Lesson 3 • Central Venous Catheter Monitoring

Explains CVP measurement technique and waveform components. Nurses connect CVP trends to preload status and right heart function assessment.

Lesson 4 • Invasive Arterial Line Setup

Covers transducer assembly, zeroing, and leveling to the phlebostatic axis. Accurate setup is prerequisite to reliable continuous blood pressure monitoring.

Lesson 1 • Respiratory Variation and Fluid Responsiveness

Explains pulse pressure variation and stroke volume variation as dynamic preload indices. Nurses apply these metrics to guide fluid resuscitation in ventilated patients.

Lesson 2 • Arterial Pressure Waveform Analysis

Deconstructs systolic upstroke, dicrotic notch, and diastolic decay. Each component is linked to specific cardiac events and vascular resistance changes.

Lesson 3 • Central Venous Pressure Waveforms

Analyzes a, c, and v waves with x and y descents in clinical context. Abnormal waveform patterns are correlated with specific valvular and pericardial pathologies.

Lesson 4 • Pulmonary Artery Pressure Waveforms

Differentiates right ventricular, pulmonary artery, and wedge pressure tracings. Nurses use waveform transitions to confirm catheter position and detect complications.

Lesson 1 • Systemic and Pulmonary Vascular Resistance

Calculates SVR and PVR from measured pressures and cardiac output. Nurses use resistance values to differentiate distributive from cardiogenic hemodynamic patterns.

Lesson 2 • Stroke Volume and Cardiac Index

Derives stroke volume and indexes cardiac output to body surface area. Body-surface-area indexing allows valid comparisons across patients of different sizes.

Lesson 3 • Ventricular Function Assessment

Evaluates left and right ventricular performance using filling pressures and output. Nurses identify systolic versus diastolic dysfunction patterns from hemodynamic data.

Lesson 4 • Integrating Parameters into a Profile

Synthesizes multiple hemodynamic variables into a coherent clinical picture. Nurses use pattern recognition to classify hemodynamic states and prioritize interventions.

Lesson 1 • Catecholamine Pharmacology

Compares receptor profiles of dopamine, norepinephrine, epinephrine, and dobutamine. Nurses predict hemodynamic effects and select agents based on the patient's profile.

Lesson 2 • Infusion Safety and Titration Protocols

Establishes weight-based dosing, double-check procedures, and titration documentation standards. Nurses prevent medication errors through systematic infusion management practices.

Lesson 3 • Vasopressin and Non-Catecholamine Vasopressors

Explains vasopressin, phenylephrine, and angiotensin II mechanisms and indications. Nurses apply these agents when catecholamine-sparing or receptor-specific effects are needed.

Lesson 4 • Vasodilator Therapy in Hemodynamic Management

Addresses nitroprusside, nitroglycerin, and clevidipine for afterload and preload reduction. Nurses titrate vasodilators to optimize cardiac output without causing hypoperfusion.

Lesson 1 • Hypovolemic Shock and Fluid Resuscitation

Defines hemorrhagic and non-hemorrhagic hypovolemia by hemodynamic signature. Nurses apply fluid responsiveness assessment to guide resuscitation volume and rate.

Lesson 2 • Refractory Shock and Escalation Strategies

Addresses shock unresponsive to standard vasopressor and fluid therapy. Nurses recognize refractory states and coordinate timely escalation to advanced support.

Lesson 3 • Distributive Shock and Vasopressor Therapy

Characterizes high cardiac output with low SVR as the distributive pattern. Nurses titrate vasopressors to restore perfusion pressure while monitoring end-organ response.

Lesson 4 • Cardiogenic Shock Recognition and Response

Identifies low cardiac output with elevated filling pressures as the cardiogenic pattern. Nurses initiate inotrope therapy and prepare for mechanical support escalation.

Lesson 1 • Right Heart Failure Hemodynamic Management

Distinguishes right ventricular failure hemodynamics from left-sided failure. Nurses avoid interventions that increase RV afterload and apply RV-specific support strategies.

Lesson 2 • Hemodynamics in Mechanical Ventilation

Explains how positive pressure ventilation alters preload, afterload, and cardiac output. Nurses adjust hemodynamic management when ventilator settings change significantly.

Lesson 3 • Hemodynamic Goals in Specific Conditions

Defines individualized hemodynamic targets for traumatic brain injury, liver failure, and renal failure. Nurses apply condition-specific pressure and flow goals to prevent secondary injury.

Lesson 4 • Post-Cardiac Surgery Hemodynamics

Addresses unique physiology after cardiopulmonary bypass including vasoplegia and stunning. Nurses manage protocolized weaning from vasoactive support in the cardiac ICU.
