Hyperbaric Oxygen Therapy in the management of foot ulceration and its Literature review

Hyperbaric Oxygen Therapy in the management of foot ulceration and its efficacy within the lower limb - Literature review Example Wound in lower limb are common and have tendency to turn chronic. There are basically 3 types of ulcers which can present in the lower limb. They are venous stasis ulcers, arterial or ischemic ulcers and neuropathic or diabetic ulcers. It is important to identify the type of wound because management and prognosis are different for different types of wound. Venous stasis ulcers are mainly located below the knee and in the inner aspects of the leg just above the ankle, like the medial malleolus (Gabriel and Camp, 2008). They occur when inadequate action of the calf muscle to pump out blood results in venous hypertension (Gabriel and Camp, 2008). The base of the ulcer is usually red, the borders are irregular and the ulcer may be covered with yellowish tissue. Fluid drainage is a characteristic feature of venous ulcer. The surrounding skin will be discolored and swollen and may feel warm (Gabriel and Camp, 2008). Ischemic or arterial ulcers are usually located in the feet, especially in regions where there is friction between toes or parts of feet with shoes, or when there is a deformity. They are more likely to occur in the periphery where there is decreased blood supply. The ulcer base is yellowish, grey or black and does not bleed (Gabriel and Camp, 2008). The borders are initially irregular and later have a regular appearance. Neuropathic ulcers commonly occur in diabetic patients and they are usually located at pressure points on the plantar aspect of the feet. Neuropathy causes loss of foot sensation and also changes in sweat-producing glands increasing the risk of being unaware of foot trauma, injuries and callosities. The ulcers appear punched out with the surrounding skin callosed. The ulcer may appear pink or brown (Gabriel and Camp, 2008). Lower extremity ulcers have varied prognosis and are associated with many complications. They are the

Assign 5 mjtjm - Assignment Example he author demonstrates the questions remains unanswered by stating that there is the absence of accepted viewpoints as the existing hypothesis were mainly on qualitative considerations that allowed different interpretation. The author chooses to use quantitative factors to answer the questions. The author mentions prior research carried out by Humphreys (1929 and others). The researcher considered that the variation of direct radiation was determined by the change in atmospheric transparency due to dust emitted during volcanic eruptions. However, the author disagrees with the findings arguing that the variation of the radiations could also be caused by increased atmospheric dust emitted by human activities1. The author uses observational images from the meteorological satellites, data from geological investigations on the level of volcanic activity and results of calculations of monthly mean values of radiation. There are no sampling issues involved in the research. The dependent variable in the study is that the changes in Earth’s temperature. The independent variables are the variations in the transparency of the atmosphere that depends on the level of volcanic activity. The hypothesis to be tested is precise as temperature change is related to change in solar radiations2. The author uses inferential statistics which is an appropriate approach based on the data available. The assumption is that the change in temperature and transparency in the atmosphere are linear. The author’s findings are that human activities influence the climate as the activities produce energy that produces heat that is an additional to the heat generated by the solar radiations. The author has an expectation that one of the glaciers expansions could reach the critical latitude that would result in complete glaciations of the Earth setting in. The author borrowed the conceptual definition from a piece of prior research3. The author concludes that human activities should be taken
