Focused cardiac ultrasound.

Area of Science:

• Emergency Medicine
• Cardiology
• Point-of-Care Diagnostics

Background:

• Point-of-care ultrasound (POCUS) is expanding beyond traditional cardiology.
• Non-cardiologists are increasingly using cardiac ultrasound at the bedside.
• Real-time cardiac imaging is becoming more accessible.

Purpose of the Study:

• To review the indications, techniques, and limitations of focused cardiac ultrasound (FOCUS).
• To highlight the expanding role of POCUS in critical care settings.
• To inform clinicians on the effective application of bedside cardiac ultrasound.

Main Methods:

• Review of current literature and clinical applications of FOCUS.
• Description of techniques for performing and interpreting FOCUS examinations.
• Discussion of patient populations benefiting from FOCUS.

Main Results:

• FOCUS is indicated for patients with undifferentiated shock, hypotension, chest pain, and dyspnea.
• FOCUS is valuable in suspected pericardial effusion, tamponade, pulmonary embolism, and left ventricular dysfunction.
• FOCUS is crucial for rapid diagnosis of cardiac arrest etiology.

Conclusions:

• FOCUS is a valuable, rapidly deployable tool for critical care decision-making.
• Expanding use of FOCUS by diverse clinicians enhances diagnostic capabilities at the point of care.
• Understanding FOCUS indications, techniques, and limitations is essential for optimal patient management.
