Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
Discuss a five-step systematic approach to ECG interpretation?
An electrocardiogram (ECG) is a basic test that may be performed to assess the rhythm and electrical activity of the heart. Sensors linked to the skin detect the electrical impulses produced by your heart every time it beats. A machine records these signals, which a doctor examines to see whether they are odd. An ECG may be recommended by a heart expert (cardiologist) or any doctor who suspects the individual has a heart condition, including the primary care physician.
