Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. ultrasound is a safe and painless test that uses sound waves to make images of the abdomen (belly).
During the examination, an ultrasound machine sends sound waves into the abdominal area and images are recorded on a computer. The black-and-white images show the internal structures of the abdomen, such as the appendix, intestines, liver, gall bladder, pancreas, spleen, kidneys, and urinary bladder. The gel is applied to the scan area, before contacting the ultrasound probe to your Ultrasonic waves generated from the probe are reflected from the boundary of the tissue, and the probe receive reflected waves to make an ultrasound image. However, the larger the difference in acoustic characteristics between the two tissues, the stronger the reflection and the stronger the echo (white on the screen) appears. The acoustic properties (resistance) of each tissue are related to their density, which is greater in order of bone> soft tissue> fat> air. Therefore, if you apply ultrasonic probe without gel, 99.9% of ultrasonic waves are reflected at the boundary of air - soft tissue (body). Ultrasound image should show the difference between the tissues in body (normal-lesion, etc.), not the difference between the air and body.
To solve this situation, the gel is used. In other words, when the acoustic resistance of the two media is made equal by using gel, ultrasonic waves are transmitted to body without reflection.
The other purpose of the gel is the role of lubrication, which moves the probe smoothly when performing a ultrasound scan. If the gel is not used, it may be stiff and the patient may feel pain.
An ultrasound scan uses high-frequency sound waves to make an image of a person's internal body structures. Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person's abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. The ultrasound sound waves have a hard time traveling through air, so the gel prevents any extra air space between the probe and your skin in order to create a clear image of the fetus.
Survivors usually get rid of toxins and other chemicals found in refined food, and stayed away from ingredients that may be responsible for cancer growth. High fruits and vegetables intake is also a must for them. Furthermore, a lot of survivors made sure that they do something each day that made them happy, even just for a few minutes. Another common factor is having powerful reasons to stay alive. There are terminally ill people who are saying they don’t want to die, however, those people who tend to survive actually say they want to live and they will do anything just to live.
Body substance isolation is a system of infection precautions intended to reduce nosocomial transmission of infectious agents and also tries to reduce the risk of transmission of hepatitis B virus, human immunodeficiency virus, and other infectious agents to health care personnel.
The nurse should ask, "How much water do you drink every day?", "Do you take estrogen replacement therapy?", "Are you on steroids or other immune-suppressing drugs?".
<h3>What is bacterial cystitis?</h3>
The inflammation of the bladder is termed as cystitis.
When a part of the body becomes irritated, red, or swollen it is known as inflammation.
Urinary tract infection is the cause of cystitis. When bacteria enter the bladder or urethra and begin to multiply it causes UTI.
The bacteria enter your urethra or bladder and cause an infection. It can also result when normally growing bacteria in your body becomes imbalanced.
