Since blood from donors it taken long before it has to be given to a patient, it is stored in the meantime in refrigerator to preserve it from getting spoiled. It can be […]
Hyperbaric oxygen therapy is currently used in various clinical treatment regimens like for treating carbon monoxide poisoning. These include decompression sickness, carbon monoxide poisoning, cyanide poisoning, gas embolus, gas gangrene, resistant anaerobic infections, and threatened split-thickness skin grafts. The mechanism of action in treating carbon monoxide poisoning purportedly involves increasing tissue oxygenation, which increases collagen
Synthetic oxygen carriers are also called as artificial blood or substitute blood. The Synthetic oxygen carriers are substances that can be used as alternatives to blood, when blood is required to be transfused to a patient. These Synthetic oxygen carriers or artificial blood is especially useful if due to some reason compatible blood is not
Hyperbaric Oxygen means delivering the oxygen above atmospheric pressure which is 760 mmHg (or 1 atm). Special hyperbaric chambers are made for providing hyperbaric Oxygen, which are very expensive. Hyperbaric Oxygen Uses A. Poisonings: Carbon monoxide poisoning (half life of CO at 1 atm is 214 minutes which can be reduced to 19 minutes at
Acute Systemic lupus erythematosus (Acute SLE) is a multisystem autoimmune disease caused by autoantibodies and the deposition of immune complexes. The disease affects primarily women and has a higher prevalence among African Americans. A series of clinical findings is associated with acute SLE.

The assessment of a patient with a tachycardia requires a systematic approach. First, the physician must determine whether the patient is experiencing evidence of hemodynamic compromise as a result of the tachycardia, which is generally not

This is an advanced method that can be carried out only in experienced and skilled hands especially like those of the anesthetists. A blind nasal intubation should always
Fetal distress can be caused by a host of factors; most notably, hypoxemia and hypovolemia are dangerous for the viable fetus. It is not uncommon for a pregnant patient to be affected by critical illness. Examples of nonobstetric maladies that lead to intensive care unit admission among pregnant women are hematologic issues (venous thromboembolism and pulmonary embolus,
The major complications of transfusion of blood are the following: 1. Transfusion Reactions : These reactions may be allergic or haemolytic: Haemolytic Reactions These are again divided in to Delayed Hemolytic reactions and Acute Hemolytic reactions. Allergic Reactions These are usually mild, manifesting as urticaria and are mainly due to plasma proteins. Treatment: Antihistamines (Avil)
Chronic oxygen deficiency is defined as a prolonged lack of oxygen to the body as that occurs in living in high altitudes or by having severe chronic lung disease. Chronic oxygen deficiency have the following effects : There is decreased mental efficiency due the prolonged deficiency of oxygen Sleepiness, headache, lassitude and fatigubility are also common Euphoria is also
