It may lead to (1) pulmonary embolism‚ if the thrombus dislodges and then lodges within the pulmonary arterial blood flow‚ and (2) postphlebitic syndrome‚ which consists of edema‚ pain‚ and skin changes due to destruction of venous valves. Doppler ultrasound scanning Imaging technique commonly used to measure blood flow. A transducer is placed on the skin and an image is displayed on a monitor that provides the exact position and severity of a blockage. Femoral angiography

Snorkeling (British spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask‚ a shaped tube called a snorkel‚ and usually swimfins. Spearfishing is an ancient method of fishing that has been used throughout the world for millennia. Early civilizations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks. Today modern spearfishing makes use of elastic powered spearguns and slings‚ or compressed gas

Dobutamine‚ a synthetic catecholamine bearing chemical structural resemblance to dopamine‚ is a beta-adrenoceptor agonist. It has remained the drug of choice in management of acute heart failure patients with systolic dysfunction. Mechanism of action: Clinically available preparations of dobutamine are a racemic mixture of (+) and (–) isomers and have complex pharmacological effects. While both isomers are full agonists at β1 and β2 receptors their effects on alpha receptors are contrasting. The

An evaluative study was carried out by Chalmers et al. in 2002 to assess three experienced nurses and radiographers performing angiographic procedures. They were provided training by a radiologist and were then instructed to perform either peripheral or renal angiograms by inserting a 3F catheter into the abdominal aorta from a femoral approach. Out of the total procedures performed‚ only 15 cases required the assistance of the radiologist. All the cases were reported as diagnostic by the radiologist

Symbicort - Budesonide and Formoterol Beta2 Agonist‚ Corticosteroid‚ Inhalant (Oral) Formoterol relaxes bronchial smooth muscle by selective action on beta2 receptors with little effect on heart rate. Formoterol has a long-acting effect. Budesonide is a corticosteroid which controls the rate of protein synthesis‚ depresses the migration of polymorphonuclear leukocytes/fibroblasts‚ and reverses capillary permeability and lysosomal stabilization at the cellular level to prevent or control inflammation
