Observe the rise and fall of the victim's chest and count the number of respirations out loud for one full minute. One respiration consists of one complete rise and fall of the chest, or the inhalation and exhalation of air. The normal respiratory rate for a healthy adult at rest is 12-to-20 breaths per minute.ne respiration consists of one complete rise and fall of the chest, or the inhalation and exhalation of air.

Hemoglobin electrophoresis (also called Hgb electrophoresis), is a test that measures the different types of hemoglobin in the blood.gb A 1 is the major component of hemoglobin in the normal red blood cell. Hgb A 2 is a minor component of normal hemoglobin, comprising approximately 2-3% of the total. Hgb F is the major hemoglobin component in the fetus, but usually exists only in minimal quantities in the normal adult.
DNA Gel Electrophoresis is a technique used to separate and identify DNA fragments based on size. DNA fragments of various sizes are loaded into a porous gel made from agarose â a carbohydrate found in red algae.ummary. DNA gel electrophoresis is a technique used for the detection and separation of DNA molecules. An electric field is applied to a gel matrix comprised of agarose, and within the gel, charge particles will migrate and separate based on size.
