Housekeeping & Course Orientation

• Best to follow on computer (larger screen, clearer view of tools).
• Course language: English.
• Focus is clinical, not theoretical, but theory explained when essential.
• Course aim: Teach practical, clinically relevant echocardiography (Echo).
• Course material (book) can be emailed.
• Participants encouraged to ask questions.

📌 Echo Training Levels

• Field/FEEL & FICE level (basic):
  • Focused echo in life support/emergencies.
  • Recognize acute PE, pericardial effusion, tamponade, standstill, cardiac rupture.
  • Acquire 5 basic echo views, differentiate causes of arrest/shock.
  • Goal = recognize abnormality, do not make premature diagnoses, refer when in doubt.
• Level 1:
  • Acquire all standard views.
  • Recognize normal vs abnormal.
  • Diagnose common pathologies (regional wall motion, valve disease, types of shock).
• Level 2:
  • Comprehensive TTE/TOE, more advanced exams.
• Level 3:
  • Specialist level (invasive echo, referrals, years of work).

📌 Teaching Approach

• Uses mannequins, heart models, and probes to build 3D understanding.
• Echo is best learned by visualizing anatomy in 3D.
• Both TTE and TOE understanding needed.
• Practical hands-on practice essential (at least one exam/month for logbook).

📌 Probe Locations & Basic Views

• Probe positions: Parasternal, Apical, Subcostal (plus Suprasternal for advanced).
• Five basic views:
  1. Parasternal long-axis (PLAX)
  2. Parasternal short-axis (PSAX) (multiple slices: aortic, mitral, papillary, apical)
  3. Apical 4-chamber (A4C)
  4. Subcostal 4-chamber (SC4C)
  5. Subcostal IVC
• Movements: sliding, tilting, rocking, rotating.
• Anatomical landmarks explained in detail (valves, septa, papillary muscles, pericardium, effusions).

📌 Structured Echo Report (Critical Care Focus)

• Differs from cardiology reports:
  • Type of exam, indication, support (ventilation, inotropes/pressors).
  • Image quality (poor/average/good).
  • LV & RV function, valves, pericardium, pleura, great vessels, hemodynamics (CO, PAP).
  • Dynamic context: mention drug support & physiological state (e.g. norad dose, pH).
  • Conclusion & recommendations.
• Reports should always include date, time, operator, and level of echo competency.

📌 Echo in Critical Care vs Cardiology

• Intensivists focus on functional echocardiography (shock, hypoxia, dynamic changes).
• Cardiologists focus on structural lesions.
• Critical care echo includes:
  • Assessing systemic vascular resistance, type of shock.
  • Serial/follow-up exams to tailor management.
  • Integration with ventilation and hemodynamic support.
• Echo is a bedside, non-invasive, dynamic tool — but underutilized due to lack of trained personnel.

📌 Clinical Applications

• Every ICU patient with shock or hypoxemia should get an echo within 24h.
• Differentiates shock types (distributive, obstructive, cardiogenic).
• Identifies treatable causes (e.g., tamponade, massive PE, LV outflow obstruction).
• Case examples: undiagnosed atrial myxoma mistaken for septic shock.
• Echo complements but does not fully replace invasive monitoring (e.g., Swan-Ganz).

📌 Teaching Interaction

• Poll questions & quizzes used to test recognition of views and clinical application.
• Assignments: record and send 5 basic views (while anonymizing patients).
• Aim: practice, optimize images, build stepwise competency.

📌 Key Messages

• Echo is a powerful diagnostic and management tool in ICU.
• Learn step by step, from anatomy → probe handling → basic → advanced views.
• Reports must be structured, contextual, and clinically meaningful.
• Dynamic, serial assessments are crucial in critical care.
• No “one-size-fits-all” approach to fluids/pressors — echo personalizes management.

✅ In summary:

This was an introductory lecture for a critical care echo course, emphasizing practical, stepwise training. It covered housekeeping, course focus (clinical not theoretical), levels of echo competency, probe positions, five basic TTE views, reporting structure, and the difference between cardiology vs intensivist use of echo. It reinforced that echo should be a routine, dynamic tool in ICU management, guiding therapy in shock and hypoxemia.
