The crashing patient: hemodynamic collapse.

Area of Science:

• Critical Care Medicine
• Cardiovascular Physiology
• Emergency Medicine

Background:

• Circulatory collapse necessitates rapid restoration of tissue perfusion and oxygenation.
• Effective management of cardiovascular collapse relies on timely evaluation and intervention.

Purpose of the Study:

• To provide an evidence-based framework for technological and conceptual advances in evaluating and managing cardiovascular collapse.
• To highlight modern approaches to patient resuscitation in shock.

Main Methods:

• Review of current literature on technological and conceptual advances in shock management.
• Focus on point-of-care ultrasound (POCUS) for initial undifferentiated shock evaluation.
• Emphasis on dynamic parameters for assessing fluid responsiveness and guiding therapy.

Main Results:

• The Ventilate-Infuse-Pump rule remains the initial approach.
• POCUS is the preferred modality for initial shock assessment, aiding diagnosis, fluid responsiveness evaluation, and therapy response.
• Dynamic parameters (passive leg raise, stroke volume variation, pulse pressure variation, IVC collapsibility) are recommended post-initial fluid resuscitation.

Conclusions:

• Patients in cardiovascular collapse present a significant clinical challenge.
• An integrated approach using bedside ultrasound, dynamic fluid responsiveness assessment, and tissue perfusion surrogates enhances shock evaluation.
• Modern methods make shock assessment faster, safer, and more physiologic.
