HOW TO DETERMINE PCV (PACKED CELL VOLUME)

The Packed Cell Volume (PCV) Test 1. Objective: This is one of the oldest tests done in medical practice. The objective of this test was to determine the percentage of red blood cells (RBCs) in whole blood. It  also helped to assess the blood’s capacity to carry oxygen. ________________________________________ 2. Principle: The test was based on the principle that when blood was centrifuged, the red blood cells settled at the bottom of the tube, forming a packed column. The ratio of the packed RBC column to the total blood column gave the packed cell volume (PCV), expressed as a percentage. ________________________________________ 3. Materials: • Microhematocrit capillary tubes • Microhematocrit centrifuge • Plasticine or sealing clay • Microhematocrit reader • Lancet • Alcohol swab • Cotton ________________________________________ 4. Procedure (Microhematocrit Method): 1. The fingertip was cleaned with an alcohol swab and pricked with a sterile lancet. 2. Blood was collected into ...

Infants do not have well-developed swallowing reflexes and may choke if given small, rounded foods such as peanuts or hard candies.   Children, especially toddlers, also may choke on balloons, toys, coins, other inedible objects that they place in their mouth, and foods (particularly rounded, smooth foods, such as hot dogs, round candies, nuts, beans, and grapes). If the airflow is blocked, choking can be a medical emergency and needs urgent attention. Choking is a leading cause of injury and death among children, especially those younger than 4 years of age. The majority of choking-related incidents among children are associated with food, coins, and toys. According to the College ...

FIRST AID FOR CASUALTIES IN SHOCK

When a person is in shock, his or her organs aren't getting enough blood or oxygen. Shock may result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns, or other causes. The main symptom of shock is low blood pressure. Other symptoms include rapid, shallow breathing; cold, clammy skin; rapid, weak pulse; dizziness, fainting, or weakness. There are 5 TYPES OF SHOCK you should be aware of and be ready to respond to in emergencies; 1. SEPTIC SHOCK: septic shocks occur from infections affecting the whole body that lead to low blood pressure. It affects infants, the elderly, and persons with weakened immune systems. Bacteria, fungi, and some viruses–upon gaining entrance into the body—could elicit septic shock. 2. ANAPHYLACTIC SHOCK(Anaphylaxis):This is a severe allergic reaction affecting the whole body.

Tetrahydrocannabinol is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant.THC is the main psychoactive compound in marijuana. It's what makes people feel "high."  THC and its metabolites are stored in body fat before finally clearing out through the kidneys.  For someone who has used it daily for so long, your body will be completely saturated with the stuff for some time after quitting.  At 83 days, you're pretty much right on the edge of having it out of your system but just aren't quite there yet.  One-time use will usually stay in your system for 5-8 days. If you use cannabis 2-4 times per week and then stop, you'll test positive for 11-18 days. Long-time heavy users should expect positive results for at least 90 days after cessation and even up to 120 days for those who are larger or with a slow metabolism.  HOW TO REDUCE THC IN TH...

Honey Nutrition Facts & Health Benefits

Honey Nutrition Facts &  Health Benefits The sugar we all are accustomed to is produced in two principal ways, from beet or cane. In production sugar is extracted and refined, before consumption. Sugar is primarily made of sucrose. Honey, on the other hand,  is made by bees using the nectar of flowering plants and stored in combs until when collected for use. Honey is primarily made up of  Fructose, followed by glucose and sucrose. The sweet taste of honey is attributed to its higher fructose content, and fructose is known to be sweeter than glucose or sucrose. From the above  explanation, we see that honey is sugar (contains sucrose), but it's sweeter, safer to use and it isn't inflammatory.  In addition to its use as a natural sweetener, honey is used as an anti-inflammatory, antioxidant and antibacterial agent. People commonly use honey orally to treat coughs and topically to treat burns and promote wound healing. On the other hand,sugar is indeed inflamm...
