Physiology of deep-sea diving is the predominant concept which has been brought under discussion in this sqadia.com medical video lecture. This V learning lecture provides a thorough comprehension of hyperbarism, Boyle’s law along with the nitrogen narcosis and oxygen toxicity. Furthermore, CO2 toxicity, decompression sickness together with the SCUBA diving has been explicated. Moreover, hyperbaric oxygen therapy alongside its uses have been elaborated.
Effect of Sea Depth on the Volume of Gases
In this lecture ´´Physiology of Deep-Sea Diving´´ is explained. Section one is about ´´Effect of Sea Depth on the Volume of Gases´´. At first hyperbarism is explained. Next is the elucidation of relationship of pressure to sea depth. After that educator reports the effect of sea depth on the volume of gases. Then Boyle’s Law is pursued. Lastly, effect of sea depth on the volume of gases is discussed.
Effect of High Partial Pressures of N and O2
Section two is about ‘’Effect of High Partial Pressures of N and O2’’. Educator started this section by elucidating nitrogen narcosis at high nitrogen pressures. In the next slide the process of nitrogen narcosis is explained. Then information is delivered on oxygen toxicity at high pressures. Moreover, acute oxygen poisoning is discussed. This is followed by Chronic Oxygen Poisoning.
Effect of High Partial Pressures of CO2
Section three is about ‘’Effect of High Partial Pressures of CO2’’. Educator’s prime focus is CO2 toxicity at great depths in the sea. Following this, CO2 toxicity at great depths in the sea is explained. After that symptoms of CO2 toxicity are reported. Moving onward, decompression of diver after excess exposure to high pressure comes under consideration. Then decompression sickness is pursued. At last saturation diving and use of helium-oxygen mixtures in deep dives is highlighted.
Section four is about ‘’SCUBA Diving’’. This section is started by the explanation of self-contained underwater breathing apparatus. In the next slide information is revealed on components of SCUBA diving apparatus. Then working of SCUBA diving apparatus is discussed. At last, educator highlights the limitations of SCUBA.
Special Physiological Problems in Submarines
Section five is about ‘’Special Physiological Problems in Submarines’’. In this section educator discuss escape from submarines and how it happens. Next focus is the health problems in submarine internal environment. Moreover, hyperbaric oxygen therapy comes under consideration. Finally, uses of hyperbaric oxygen therapy are pursued by the educator.
