What is medimist inhalation?

User Avatar
I am going to presume that you mean a MediMist Nebulizer. This is a machine used to administer medication to people in the form of a mist inhaled into the lungs. It is commonly used in treating cystic fibrosis, asthma and other respiratory diseases.

A diplomate in medical terms is someone with board certification. Well the answer could be (see below) A diplomat is a person usually works in the system of 'Ministry of Foreign Affairs' of a particular country and who represents their government when working in a embassy abroad.

Why flex head forward when inserting a ng tube?

this position helps place the Ng tube into the esophagus instead of the trachea by slightly blocking the airway and giving an open unresisting path into the esophagus.

Why is it dangerous to be exposed to X-rays but not or at least much less dangerous to be exposed to radio waves?

User Avatar
X-Rays lie at a different end of the electromagnetic spectrum to radiowaves. X-Rays are very high frequency and very small wavelength. This means they are very high in energy. As a chemist I can use X-Rays to knock electrons out from low lying orbitals or cleave covalent bonds....both are very dangerous to biological systems (kinda like being shot by tiny bullets, smashing things apart such as DNA and essential proteins). This also means we get radicals and other reactive species that will undergo unnatural reactions in our bodies (in many cases, they can be oxidising which is very dangerous in the highly reducing environment of our bodies). If X-Rays are like tiny bullets, radiowaves are like tiny pingpong balls. You get hit by one and it's not a big deal. They will transfer some energy to you....some will pass right through you. But generally do not possess enough energy to do any major harm. This is a very basic overview. If you want to dig a little deeper, look up 'electromagnetic spectrum' and note how the less harmful things appear on the low-energy (long wavelength) side of the IR and visible light as opposed to harmful radiation such as UV and X-Rays on the higher energy side.

How to determine X ray magnification factor?

User Avatar
Your magnification factor is SID divided by OID. [MF = SID/OID] So for example: If your SID was 40 and your SOD was 32 Your magnification factor = 40/32 = 1.25 -- This means the image will appear 25% larger than the actual object. (It's the size of 1 plus 25 percent more of the original.) Example 2 if you're trying to figure out original object size: Your object size equals your image size divided by the magnification factor (MF). [object size = image size/ MF] If you have an object on an image that measure 70 inches when your SID was 100 and your OID was 65, how big was the original object? MF=100/65= 1.54 (rounded) Object size = 65/1.54 = 42.21 The object imaged was 42.21 inches before magnification.

How do you find relief from dizziness?

User Avatar
Salt, Vinegar, Mustard, Nacho cheese, Pepper and Cayenne in small and equal proportions should be mixed to a cup of water and consumed. Blood circulation increases and makes you feel clearheaded and steady. A solution of Lemon juice, Black Pepper, Salt and Water is also an excellent solution for Dizziness. A mix of Honey and Apple Cider Vinegar is greatly helpful in clearing Dizziness quickly. Yoghurt mixed with orange, lemon and Tangerine peels relieves dizziness to a great extent. Chamomile tea or Peppermint when consumed restores normalcy. A massage with Lavender greatly helps in relieving dizziness. Pure ginger juice in small quantities relieves the pressure. Alternately ginger juice along with honey can be taken for better results, since honey has so many curative properties. If you want a remedy that doesn't include eating or drinks placing you head between your knees usually helps as well. You can also try motion sickness over the counter medication. If the condition persists, you should visit your doctor.

What is ligamentum flavum hypertrophy?

User Avatar
ligamentum flavum hypertrophy is a degenerative condition of the spine which most commonly occurs in the elderly where the tendons holding one vertebra to another thicken, decreasing the amount of room available for the spinal cord and the nerves that come off it. It may be associated with inflammation (arthritis) or osteoporosis. It is frequently treated surgically, and it can recur. This one seems a bit complex to answer easily, So if you follow the related link (Hypertrophy of Ligamentum Flavum in Lumbar Spinal Stenosis) you will find more information.

Why can't X-rays pass through lead?

User Avatar
X-rays can pass through lead. X-rays can pass through just about everything. Therapeutic level x-rays can pass through 10 feet of concrete and lead. However, in diagnostic x-ray only 1/4" of lead in the protective aprons is necessary to block most of the x-rays at that level of radiation. X-rays actually can pass through lead. But the amount of X-rays that is blocked is proportional to the density. E.g. Water has density 1 and lead has density 11.36. Therefore water lets pass 11.36 times more X-rays than lead.

Which sorts of materials are transparent to x-rays?

User Avatar
X rays are are able to penetrate less dense materials easily, such as muscle and skin tissue in medical situations or plastics and wood in other applications. As the material becomes more dense, the x rays penetrate less easily. Materials such as steel or bone in a medical setting are more dense along with such materials as lead and tungsten in engineering situations.
Asked in Health, Medical Technologies, MRI

How often can an MRI be performed on the same person safely?

User Avatar
MRI uses high magnetic fields and radio frequency and not x-ray. The procedure is generally safe and typically repeated examinations do not cause any problems. However, some MRI scans use a Gadolinium-based contrast agent, so repeating MRI scans within a few days may expose a patient to higher-than-expected levels of the contrast agent in the blood, which can be affected by kidney function. Patients should check with their doctor before having a repeat contrast MRI scan within a few days.

What Does Radiolucent mean that it can not be seen on a x ray or an ct scan?

User Avatar
Radiolucent indicates a structure which lets relatively more x-rays through than the adjoining structures. The radiolucent structure is black on film, and the radio-opaque structure is white. Everything is relative. From radiolucent to radio-opaque, in a progressive order are air, fat, water (soft tissues), bone, metal.
