ODC Tutor vs NCLEX Review & Prep 2026

Title: The ODC App: A Guide to Understanding the Oxygen-Hemoglobin Dissociation Curve Introduction: The ODC app is a medical tool that allows users to visualize and understand the oxygen-hemoglobin dissociation curve, an essential concept in respiratory physiology. Developed by a team of medical professionals, this app offers a user-friendly interface that displays the relationship between partial pressure of oxygen (ODC's horizontal axis) and hemoglobin saturation (ODC's vertical axis) in a sigmoid curve. Features: The app's normal sigmoid curve can be shifted to the right or left, indicating the decreased and increased affinity of hemoglobin to oxygen, respectively. The app also displays the causes for the shift in the curve, helping users understand the factors that affect hemoglobin saturation. The application shows the fall in saturation of hemoglobin as the blood moves from the arterial to venous end, and the oscillating cursor indicates the heart rate which can be changed. The app displays both arterial and venous saturation and provides P50 value, which denotes the partial pressure of oxygen at which hemoglobin is 50% saturated (marked in the application). The ICU point is an important feature that the app highlights. It marks the point where partial pressure of oxygen of 60 mm Hg corresponds to a hemoglobin saturation of 90%. At this point, a small drop in pressure leads to rapid drops in saturation, indicating the need for close monitoring in critical care settings. Team Behind the App: The ODC app was developed by a team of medical professionals, including Dr. Satish Deopujari, a Professor Emeritus at Govt. Medical College Nagpur IGGMC, Adjunct Professor in Mechanical Engineering at VNIT Nagpur, Chairman Academics at Nelson Hospital Nagpur, Founder Chairman of the National Pediatric Intensive chapter, and President of the Society of Pediatric Cardiac Critical Care in Chandigarh. Dr. Lawrence Martin, Dr. Vivek Shivhare, and Dr. Shruti Deopujari were also part of the development team. Their collective experience in the medical field has contributed to the development of medical education and research in India.
