Heliox is a mixture of Helium and oxygen being considered for use in asthma patients. Therapeutic strategies for patients with pulmonary medicine often employ bronchodilators or corticosteroids to reduce airway resistance and improve airflow. As an alternative strategy, viscosity and density of the atmosphere manipulated to the same desired effect. Air consists of 21% oxygen, with
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
Unstable tachycardias can be manifested by chest pain, shortness of breath, decreased urine output, mental status changes, or hypotension. 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

Following are the Hypoxia signs Psychological Hypoxia signs – Higher centers are first impaired in hypoxia due to deficiency of oxygen to the brain tissue. Psychomotor and emotional judgement is poor in the absence of oxygen. The mechanisms mediating cerebral vasodilation during hypoxia are not fully understood but may include neurogenic effects initiated by peripheral and neuraxial chemoreceptors,
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 capacity of deliberate Brain Hypothermia to protect the brain and other vital organs during periods of decreased oxygen delivery is used during cardiac surgery. The beneficial effects of Brain Hypothermia were empirically attributed to its ability to decrease cellular metabolism and thus delay the processes leading to irreversible cell death. Based on this, it
The Emergency Medical Treatment and Active Labor Act (EMTALA Act) was passed by the U.S. Congress in 1986 to prevent hospitals from rejecting, refusing, or transferring patients because they are unable to pay or because they have public health insurance. The main purpose of EMTALA Act is to ensure nondiscriminatory patient access to emergency medical
Clinical Causes of Hypoxia During Anesthesia Every doctor should know the answer to the basic question What causes Hypoxia . Factors responsible: 1. Preanaesthesia factors • Poor physiological status • Drug intake • Premedication with narcotics and sedatives depress the respiration • Decreased compensatory mechanism due to any cause 2. Decreased partial pressure and concentration of the inspired oxygen in
If you want to convert MMhg to CMh2o the following knowledge is important for this. Pressure is defined as the force per unit area. It can be applied either to a solid or a liquid interface at a point perpendicular to the surface and is represented by the height of the column that exerts a
Nitrogen is present in the atmosphere and it constitutes 78.08% of total air. Moreover, the use of nitrogen is growing very rapidly these days. Use of nitrogen in medicine is helpful as it can be used as diluent of oxygen in order to avoid oxygen toxicity. It is stored in either compressed air or in
