Quick Revision Facts Ep 11 | P50 | Digitalis Toxicity | Dr. MEK #anesthesiology #anesthesia

Episode 11 of Dr. MEK's Quick Revision Series! This episode covers essential high-yield medical topics for rapid revision, perfect for all medical exams, especially for anesthesia and medical viva prep. 🚀 Topics Covered in This Episode: 👉 Slowest Conduction Velocity – C Fibers ✅ C fibers have the slowest conduction velocity among nerve fibers (0.5–2 m/s). These unmyelinated fibers transmit chronic, dull, burning pain and autonomic signals. 👉 T Wave in Digitalis Toxicity ✅ In digitalis toxicity, the T wave typically becomes flattened or inverted, not increased in amplitude. Other ECG findings include ST depression, PR prolongation, and arrhythmias. 👉 P50 for Normal Adult Hemoglobin – 25 mmHg ✅ The P50 value for normal adult hemoglobin is approximately 25 mmHg, indicating the partial pressure of oxygen at which hemoglobin is 50% saturated. A right shift increases P50, favoring oxygen unloading, while a left shift decreases P50, increasing oxygen affinity.
