Oxygen is a vital molecule essential for sustaining life, and its efficient transport from the atmosphere to the cells is a key concern in anesthesia. As anesthesiologists, understanding the nuances of oxygen’s journey, from its initial entry into the body to its ultimate utilization in cellular metabolism, allows us to optimize patient care, particularly during … Read more
The Oxygen Reserve Index (ORi) is a groundbreaking, non-invasive monitoring parameter that provides anesthesiologists with crucial insights into a patient’s oxygenation status. As a relatively recent innovation in the field of perioperative monitoring, ORi offers a new dimension to oxygen monitoring, especially in the moderate hyperoxia range, where traditional pulse oximetry reaches its limitations. By … Read more
Regional and local anesthesia are essential techniques in modern anesthesiology, offering benefits such as reduced systemic effects and improved postoperative pain control. However, these techniques are not without challenges, particularly regarding their impact on oxygen delivery (oxygen flux) and hemodynamic stability. An understanding of how regional and local anesthesia can influence oxygen flux is critical … Read more
On this Teacher’s Day, we pay homage to the pioneers and educators in anesthesiology who have shaped the speciality, making modern surgery safer and more effective. The evolution of anesthesia, from its rudimentary beginnings to its current state as a highly specialized field, owes much to the visionaries who dedicated their lives to teaching and … Read more
Introduction In recent years, significant advancements in smart oxygen delivery systems have transformed the landscape of respiratory therapy, offering anesthesiologists and healthcare providers powerful tools to enhance patient care. These innovations respond to the growing need for personalized, responsive, and adaptive respiratory support for patients in various clinical settings. From operating rooms to home care … Read more
During surgical procedures, maintaining adequate oxygen delivery to tissues is crucial for preventing cellular hypoxia and ensuring optimal patient outcomes. Oxygen flux, which refers to the delivery of oxygen from the lungs to peripheral tissues, is primarily determined by cardiac output (CO) and arterial oxygen content (CaO₂). The type of anesthesia utilized can significantly affect … Read more
