Abstract

Reduced oxygen supply, excessive oxygen consumption, or insufficient oxygen utilization1 causes cellular and tissue hypoxia, which is characterized as shock. Hypoperfusion, for whatever reason, causes cells to malfunction due to insufficient oxygen and substrate supply. Initial resuscitation in shock patients involves administering fluids to raise preload and, by extension, cardiac output. It is crucial to avoid fluid overload and hypovolemia while treating shock patients. Pulmonary edema, increased intraabdominal pressure, and increased intracranial pressure are complications that may occur or worsen if fluids are given to a patient who is not responding. Therefore, before trying volume expansion, it is crucial to identify possible fluid responders. Researchers in this study assessed the efficacy of the passive leg raising test in assessing fluid responsiveness in patients with septic shock by measuring changes in mean arterial pressure and pulse pressure.
