Carbon dioxide was discovered by Von Helmont and was isolated by Joseph Black in 1757. Physical properties of carbon dioxide were shown by Yandell Henderson in 1925 and J S Haldane in 1926. It was frequently used to stimulate respiration and there was provision for carbon dioxide cylinders on old Boyle’s machines. The physical properties of
The aim of the airway device is to prevent the tongue fail. The tip of airway gets inserted between tongue and posterior pharyngeal wall and thus prevents the tongue failing back on posterior pharyngeal wall. The various usages of the airway device are: As an alternative to intubation where difficult intubation is anticipated. Securing airway in
Cranial Perfusion Pressure is the blood pressure in the brain that is required to maintain adequate circulation in the brain and thus maintain the important cerebral functions. Very low Perfusion Pressure in the brain will result in inadequate circulation to the brain and reduced oxygen and glucose supply to the brain with which it functions. The
Hemolytic Reactions Hemolytic reactions can be: Acute Hemolytic reactions Delayed Hemolytic reactions: The Delayed Hemolytic reactions are seen after a few days of blood transfusion. Acute hemolytic reactions It is usually due to ABO incompatibility (mismatch reaction). The most common cause of these transfusion reactions is clerical error. There is intravascular hemolysis. Incidence is
