in educating the community regarding the efficiency and safety of the currently licensed vaccines. Polio has been the most feared illness during childhood. Polio has caused paralysis and most deaths in the past. A dramatic polio increase was experienced around 1910 all over the world. The regular polio epidemics served as a driving force towards the development of polio vaccines. (procon.org)The polio vaccine was developed in the year 1953 while its oral version followed after. According to American
Premium Vaccination Vaccine Immune system
Polio is known as the “crippling and potentially deadly infectious disease. It is caused by the poliovirus. The virus spreads from person to person and can invade an infected person’s brain and spinal cord‚ causing paralysis (can’t move parts of the body)”as said by the CDC. Jonas Salk encountered polio in everyday life and he started to create the vaccine. Now in the 21st century Polio is very rare and there is zero known cases in the US. Jonas Salk explored the many strings of the virus and used

How to Take a Pulse The pulse refers to the pressure of the blood pushing against the wall of an artery‚ (a blood vessel that carries blood away from the heart)‚ as the heart beats and rest. When taking a pulse you are counting beats per minute‚ (the rate) and recording three different facts about the pulse the rate‚ the rhythm‚ and volume of pulse. These facts are very important to complete information and help in assessing your patient. Also‚ when taking a pulse find arteries that lay close

THE INTERPRETATION OF THE POSITIVE VENOUS PULSE.* ALBION WALTER HEWVLETT‚ M.D. (Assistant Professor of AMedicine at thze Cooper Medical College‚ San Francisco‚ Cal.) INTRODUCTION. The normal venous pulse is characterized by the presence of two main waves. The first of these‚ the a wave‚ is due to the contractioni of the right auricle‚ and immediately precedes the carotid pulse. The other‚ or v wave‚ appears in the neck in early diastole coincident with the closure of the semilunar valves

How to Check a Patient’s Radial Pulse Whether you are thinking of going into the medical field as a doctor or nurse or starting at the bottom as a certified nurse assistant‚ you will need to learn the basics of taking vital signs. The very first vital sign you learn as a medical student is taking a pulse. Pulse measures the rate at which your heart beats. Also the rhythm and the strength (strong or soft) can be determined as well. Checking pulse helps determine the condition of your heart; and gives

Biology Task To investigate the effect of some factor affecting pulse rate Aim TO investigate how exercise affects the pulse rate. To do this‚ we took our normal pulse rate and then compared it with the pulse rate after exercise (walking). We kept all other factors constant so as to study the effect of exercise on pulse rate. Introduction Our heart is a muscle. It’s located a little to the left of the middle of our chest‚ and it’s about the size of our fist. There are lots of muscles all over

Pulse and Blood Pressure Lab (after lesson) Objectives: 1. To allow students to formulate and test hypotheses. 2. To allow students to practice taking pulse and blood pressure. Teacher notes: 1. Briefly review of how to take a pulse and a blood pressure (if necessary) 2. Instruct students to pair off 3. Students will fill out the lab worksheet which will help guide them in the lab. Answers to the questions: Using what you know about pulse and blood pressure‚ form a hypothesis about what

exercise on cardiovascular functions such as pulse rate‚ pulse lag‚ the PT interval‚ the TP interval‚ systolic‚ and diastolic blood pressure is noticeable after running down the steps of Long Hall and back up to the third floor. As Table 1 shows‚ the data support the initial hypothesis that the pulse rate will increase‚ the pulse lag will decrease‚ both the PT and TP intervals will decrease‚ and the systolic and diastolic blood pressure will increase. The pulse rate mean before exercise was about 78 beats
