SCCM Resource Library-The Peculiar Physiology of Blood Flow During CPR and How to Optimize It

Video Transcription

Video Summary

The speaker in the video discusses the physiology of blood flow during cardiopulmonary resuscitation (CPR) and different approaches to CPR. They explain that blood flow during CPR is different from that of a beating heart and discuss the cardiac pump and thoracic pump at work during CPR. They provide recommendations for optimizing blood flow, such as adjusting compression rate and depth. The speaker also discusses the use of abdominal binding and interposed abdominal compressions to increase intra-thoracic pressure. They talk about the effects of airway pressure during CPR and the use of vasopressors and hypervolemia to manipulate the arterial system. <br /><br />The video also covers the evidence and recommendations for different approaches to CPR. They discuss compression-only CPR and its equivalence to compressions with ventilation in out-of-hospital arrests. The speaker emphasizes the importance of maintaining good quality chest compressions and reviews the evidence for compression rates. They mention the positioning of the dog during chest compressions and the use of epinephrine and vasopressin during CPR. While epinephrine has been extensively studied, the evidence for vasopressin is less clear. The speaker explains the latest guidelines for the use of these medications. They conclude by highlighting the importance of considering individual patient characteristics and clinical judgment when determining the best approach to CPR.

Asset Caption

This is a presentation from the 2020 Critical Care Congress precourse, Cardiopulmonary Resuscitation, Electrolyte, and Acid-Base Disorders for the Veterinary Emergency and Critical Care Specialist. The Peculiar Physiology of Blood Flow During CPR and How to Optimize It was presented by Daniel Fletcher, PhD, DVM, DACVECC, and Manuel Boller, DVM, MTR, DACVECC.

The course covered topics including updates from research, electrolyte disorders commonly and less commonly seen in the critical care setting, importance of chloride and its role in resuscitation management and the kidney, and acid-base disorders, including physiology, blood gas interpretation, and treatment.
