Simplified Algorithm for Evaluation of Perioperative Hypoxia and Hypotension (SALVATION): A Practical Echo guided Approach Proposal

Abstract Despite the valuable use of modern applications of perioperative ultrasound across multiple disciplines, there has been limitations to its implementation restricting its impact on patient-based clinical outcomes. Point of care ultrasound evaluation of hypoxia and hypotension is an important tool to assess the underlying undifferentiated etiologies in a timely manner. However, there is a lack of consensus on the formal role of ultrasound during evaluation of perioperative hypoxia or hypotension. The previous ultrasound algorithms have adopted a complex technique that possibly ignore the pathophysiological mechanisms underlying the conditions presenting in a similar fashion. We propose a simple, sequential and focused multi-organ approach, applicable for the evaluation of perioperative hypotension and hypoxia in emergency scenarios. We believe this approach will enhance the care provided in the post-anesthesia care unit (PACU), operating room (OR), and intensive care unit (ICU).
