Common health effects of carbon dioxide include : • There is fall in peripheral vascular resistance but there is increase in mean arterial pressure. There is increase in blood flow towards skin and so more chances of oozing. • Directly it reduces contractile force of heart but indirectly increases cardiac output. It increases the sympathetic […]
In the atmosphere it is present in the concentration of 0.003%. It is stored as high pressure gas in the cylinders. There are several effects of helium Inhalation . The medical diagnostic utility is secondary to its low density, insolubility and thermal conductivity. • Molecular weight is 4. • Specific gravity is 176. • It
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
The European—American Consensus Conference in 1993 provided working definitions of Acute Lung Injury and ARDS to improve diagnostic consistency and interpretation of the results of clinical and epidemiological studies. Both Acute Lung Injury and ARDS are characterized by the presence of hypoxemia and pulmonary infiltrates without elevated left atrial pressure. The two conditions are distinguished
Electrical burn continue to be clinically and surgically challenging for surgeons and critical care physicians worldwide. Gross underestimation of the initial injury has repeatedly proven to increase morbidity and detrimental to the overall outcome. To briefly review, electricity is the flow of electrons through a conductor via the force of voltage. Voltage is categorized into
Despite the great strides made over the last decades in improving survival after thermal injury, infectious complications remain an important cause of morbidity and mortality. Nearly 50% of all burn deaths are related to infected burn. Several factors contribute to the high incidence and severity of infection in burn patients. First, a profound immune suppression
Missed injuries, commonly referred to as the trauma surgeon’s nemesis, are an expected occurrence in the management of multiply injured patients. The definition of a missed injury is institution specific. Generally speaking, however, a missed injury is an injury identified at some defined time after the initial assessment. Missed injuries are not frequently life-threatening. However,
Blood Type and Crossmatch is essential for the management of all surgical cases as well as critically ill patients. Although red cell membrane contains more than 300 antigens and 20 blood group antigens are known but still the most important Is ABO grouping because most serious mismatch transfusions reactions are usually caused by ABO incompatible
There are numerous uses of carbon dioxide in modern anesthesia. It is used : • To increase depth of anesthesia with volatile anesthetic agents by stimulating respiration.- • To increase cerebral blood flow during carotid artery surgery. • To produce hyperventilation during blind nasal intubation. • To stimulate the respiration after artificial hyperventilation. • It
Chest pain in the intensive care unit (ICU) is a common and potentially serious complaint. The differential diagnosis of noncardiac chest pain is broad, and the physician must not be limited to cardiac etiologies, although myocardial infarction and angina must always be considered. The initial approach to Noncardiac Chest Pain requires a rapid evaluation, history,
