What is CO2 Narcosis? (Hypercapnia): Causes and Pathophysiology

How carbon dioxide narcosis and hypercapnia develop, including their etiology, pathophysiology, and clinical significance.

In this Video, we have explained what is #CO2 (carbon dioxide) Narcosis in blood, its etiology and #pathophysiology in detail along with #Hypercapnia. ________________________________________________________________ Topics: 0:00 | What is CO2 Narcosis? 1:37 | Hypercapnia 2:48 | causes of co2 narcosis 5:33 | Pathophysiology of co2 Narcosis _________________________________________________________________ Learn More: ecgkid.com _________________________________________________________________ In general, acute hypercapnia is the driving force behind CO2 narcosis. The etiology of CO2 Narcosis is complex, it's useful to categorize the potential causes into three categories: decreased minute ventilation, increased physiologic dead space, and increased carbon dioxide production. Hypercapnea is a condition in which the amount of carbon dioxide dissolved in the blood rises above the normal level. It can cause neuromuscular dysfunction and often leads to a depressed level of consciousness. The minute ventilation is the respiratory rate into tidal volume. Anything that affects the central respiratory center can have an impact on minute ventilation. There is another unique Condition in which CO2 Narcosis is present. It is oxygen-induced hypercapnia, which presents in some patients with COPD when given supplemental oxygen. Increased CO2 production According to current understanding, hypercapnia alters neurotransmitter levels involved in consciousness. Normal individuals do not experience alterations in consciousness until PaCO2 is greater than 75 mmHg. Carbon dioxide is fundamental for blood circulation in the brain. Pathophysiology of CO2 Narcosis
