The Harvard Medical School professor and researcher worked as a consultant in 1967, expanding the range of stethoscopes that continue to lead the market today. The top leading models are the Classic, the Master Classic, Cardiology and Master Cardiology stethoscopes. These stethoscopes remains at the top of the list in the UK and USA for incomparable excellence and sales among internists, nurses, medical students, pediatricians and cardiologists.

This innovative, diagnostic instrument has earned it’s fine reputation as the leader in stethoscopes with a product that provides years of superior performance and service, answering the question “what is a Littmann stethoscope”. The medical profession is a field where time is critical and the cost of an error incalculable. This line offers a wide variety of stethoscopes that deliver the finest, precision instruments and superior performance available today. All models meet strict medical auscultation requirements for all diagnostic specialists.

Classic stethoscopes produce high acoustic sensitivity performance. This instrument features two-sided chest pieces with non-chill rims and diaphragm for patient well-being and comfort. One side is equipped with a tunable diaphragm with a traditional bell function on the opposite side. Convenience is evident in design, with the ability to alternate between low and high-frequency sounds without turning the chest piece.

Master Class stethoscopes are a superior, portable, single-sided unit with excellent acoustic sensitivity in an award-winning design. It features a tunable diaphragm, allowing for low and high-frequency comparisons with patient-friendly, non-chill rim and diaphragm.

Cardiology stethoscopes serve listening for both low and high frequency sounds without turning the chest piece. The small side of the non-chill diaphragm serves pediatric and thin patients well. Precision instrumentation navigates around surgical dressings or bandages.

Master Cardiology stethoscopes are designed with a handcrafted, stainless steel chest piece that is single-sided for portability. A tunable diaphragm allows alternating between low and high-frequency auscultations simply with a pressure-change conveniently on the chest piece. Difficult sites or pediatric patients are easily accommodated with a special procedure adaptor.

Today, this line of precision stethoscopes offer multi-varied, diversified models for all medical professionals. Depending on the requirements of the medical specialty, the leader in stethoscope technology consistently meets the criteria that addresses medical diagnostic needs. Nurses, medical students and all medical specialties, including veterinarian practices, demand Littmann, the finest precision instrumentation available on the market.

Advancements in technology have produced electronic blue-tooth enabled stethoscopes with recorded playback for later study. As technology grows, so does Littmann stethoscope capabilities. When someone asks “What is a Littmann stethoscope”, it is fact that the entire medical community looks to this line of stethoscopes to consistently provide state-of-the-art medical instruments that are above and beyond the rest.

Physician Assistants (PAs) play an important role in the medical field. Physician assistants are health care professionals licensed to practice medicine under the supervision of a physician. Physician assistants perform a number of tasks that include: physical examinations of patients, arrange for diagnostic testing and take part in the interpretation of test results, assist with diagnosing and treating medical conditions, writing medical prescriptions, and counseling patients on health care. Basically Physician assistants have the authority to do almost everything a doctor can do.

Physician assistant jobs are all encompassing as they alleviate much of the burden placed on physicians. With such a burden placed on physicians in all areas of medicine that includes physician jobs practices and all medical areas in hospitals, physician assistants are in great demand making this career a good choice for people who want to earn a lucrative income while helping people in need. In addition, PAs will go to health institutions such as nursing homes for follow up health care. Many PAs can also be found working in specialty medical fields such as pediatrics, internal medicine, emergency medicine, major surgery, pediatrics, geriatrics, orthopedics, and more. One of the best benefits of a career as a physician assistant is you do not have all of the demands of a physician so you can have a life outside of the workplace.

To become a physician assistant, you will take most of the same classes as physicians, but you do have to participate in all of the same internships or residencies as physicians. Physician assistants must have graduated from an accredited physician assistant program and pass the national certification exam to obtain a license. Once one secure a physician assistant job, he or she will be under strict guidelines provided by the physician. The extent of the involvement by the physician assistant in the examination and carrying out of treatment will depend on the acuteness and complexity of the patient’s condition and the experience, training, and preparation of the physician assistant as evaluated by the physician. The physician and physician assistant will work together to delegate patient services, as well as the mutually agreed upon guidelines for practice.

Like the physicians they serve, physician assistants can follow many high paying and challenging career paths that are all very rewarding. If you are looking for a career in health care, self-motivated, enjoy helping others in need, and have a minimum of two years of university education, a career as a physical assistant may be the choice for you. A physician assistant program is often a 2 year program delivered over a 24 month period. The first year consists of clinical science courses and the second year includes clinical training delivered in the consecutive 12 month period. PAs are required to take ongoing medical education classes and must retake a re-certification test to maintain their national certification.

With physician assistant jobs now in great demand and expected to increase in demand in the coming years, the Physician Assistant medical profession is well worth considering for anyone looking for a rewarding career in the medical field.

What you need to take and how much you need to spend depend on how far from home you are planning to venture and, if travelling abroad, to which countries. What activities you have planned will also influence your decisions. If water sports such as boating or kayaking feature in your travels, then waterproofing is essential. Another consideration is how many people are travelling as will, naturally, any pre-existing medical conditions.

For individual adventure trips and activities involving water, a waterproof minimum individual kit containing plasters, butterfly closures, sterile gauze, tape, moleskin, safety pins and various wipes for bee stings, itch relief and cuts and scrapes might prove useful. This would be a good place to carry any personal medications or inhalers that might be required. These cost around GBP 10.00.

A basic first aid kit to keep in your vehicle for medium to long journeys would contain larger numbers of the items in the individual kit plus a vehicle sticker, disposable gloves, eyewash pods and a foil blanket. A kit containing these items for around ten people would be around GBP 17.00 or 18.00.

Bigger adventures mean bigger injuries, so a first aid kit for a more ambitious vacation might include items like blister plasters, zinc oxide tape, burn gel, over-the-counter painkillers of different types (some people cannot take aspirin or NSAIDs like ibuprofen), a forehead thermometer, wound closure strips, scissors, tweezers, and powderless vinyl gloves. These run to around GBP 16-18.

An extended kit for ten people might contain everything in the ‘bigger adventure’ kit, with the addition of a triangular bandage, sick bags, an instant cold pack and sun cream. This will cost around GBP 25.00.

For travel to remote areas or to third world countries, doctors with experience in these areas recommend taking scalpels, silk suture, hypodermic needles and syringes. Mosquito nets and water purification tablets might also come in handy in certain circumstances.

Always take more than enough prescription medication with you in its original packaging. It is a good idea to keep a small supply for immediate use separate from your main stock. This can be as simple as using one small and one medium sized bag. It is a good idea to keep copies of prescriptions with you for border inspections. The International Narcotics Control Board (INCB) have produced guidelines and information about specific countries regarding transporting medicines that affect the central nervous system (CNS). Certain over-the-counter painkillers containing small amounts of codeine are available over the counter in Great Britain but are not available in Belgium and may even be confiscated by customs officers in some countries, so it is essential that the traveller check details if they are planning to carry any CNS medicines with them to a foreign country. Limited amounts may be permissible provided it is accompanied by suitable documentation.

When travelling to a foreign country, always check with your doctor and ascertain from that country’s embassy what the regulations are before setting out on your journey.

Many things could happen on the road and it is vitally important that people take precaution so that they are not left unprepared for an emergency while they are traveling or simply driving in their car. They should never be left behind on camping or hiking trips. Emergencies are just what they claim to be, the immediate need for help.

A supply pack can be small or large depending on the available space for carrying. Small ones will have the most essential elements of a good kit while large ones will have plenty of extras. Where you are going, what you are doing and how much room you have to carry the pack will make a big difference as to the size you choose to put together.

A good pack will have some kind of communication. A flare gun is old school but still used today on boats and for people who are traveling long distances on foot. Today, we have technology that makes the flare gun seem like it might be unnecessary. It is better, however, to have some of the basics, some things that do not require batteries or some kind of advanced technology.

Speaking of batteries, a new unopened pack of every size available is always useful, with a flashlight or two to make sure the way is always lit. These are things that are often forgotten in first aid kits because the focus is usually more on caring for the health of a person who has been hurt somehow.

The medical supplies that are included in a good kit will cover any number of wounds or injuries. Alcohol swabs to cleanse the wound should be included. Bandages and sterile gauze packs are needed to cover up a wound so that it does not get dirty and become infected. An ACE bandage is something that may be needed and does not take up a great deal of space.

If there is room in the pack, it is a good idea to have some kind of sharp instruments, although they should be stored so that it is not dangerous to the user. There should always be some kind of antibacterial ointment or spray that can be applied to a wound to help guard against infection.

First aid kit essential supplies consist of many things that are often forgotten. If the objective is to have everything that might be needed, a list should be made and organization for space will be the key. If a small pack with bandages and ointment is all that is needed, there are ready made kits available at department stores everywhere. These will usually contain bandages, ointments, medical tape, guaze, alcohol swabs and other necessary items that will help someone dress a wound so that it will stop bleeding and resist infection.

A CT scanner passes over the patient lying on a special table and records the first x-ray image. It takes a series of x-rays around the patient’s head by moving around in small increments. The computer manipulates the collection of images to produce cross-sectional and sometimes 3D views of the head. The procedure takes about half an hour and is completely painless.

Molecules like oxygen or glucose can be labelled with radioisotopes and then injected into the blood stream. From there, they migrate to regions of the brain that are metabolically active. When a radioisotope breaks down, a neutron and a position are formed. When a positron inevitably collides with an electron, both particles are destroyed yielding two gamma rays. These gamma rays are visualized via the PET scan to display a functional image of the brain.

Magnetic Resonance Imaging employs a strong magnetic field along with radio waves to produce very detailed pictures of soft tissues such as the brain. Similar to CT, the patient lies on a special table that slides into the digital imaging system. It is essential that the patient removes all exterior metal jewelry, watches, etc, and does not have any internal metal implants that can interfere with the image and cause discomfort or even damage to the patient. MRI has been in routine use since the early 1980s.

The first MRI scanners had very little space for the patient and the scans took a long time to produce – as long as 45 minutes or more. In some people, this can trigger severe anxiety or a condition called claustrophobia (the fear of enclosed spaces). For this reason, as many as 20 per cent of patients refused to go ahead with the procedure. Modern equipment allows the patient to remain standing and fewer patients are refusing. If necessary, light sedation or cognitive behavioural techniques can make the patient more comfortable.

Functional MRI can detect increased use of oxygen and glucose as well as changes in blood flow to areas of the brain that are particularly active. It therefore provides a functional as well as anatomical picture of the brain.

Following injection with a special dye, a number of x-rays are performed. This technique produces a picture of the network of the brain’s blood vessels. This is called an angiogram.

Magnetoencephalography is a new method of imaging the brain. It measures the activity of the brain in real time. In patients who are diagnosed with seizures, MEG and MRI used concurrently can assist the neurosurgeon to identify and cut out the damaged tissue and leave healthy brain behind. MEG can determine the location of the lesion more accurately than MRI on its own.

The process of taking a picture – whether for family portraits or scientific purposes – was a chore in the early twentieth century. In actuality, the camera was not really that old at that point. It had not been so long ago when tin types and shutters that took hours to close were the norm for photographic activities. However, in the 1970s, scientists came up with a solution to this problem.

In order to avoid the operational weaknesses of the common camera then in use, they invented a form of digital imaging to use in scientific research and military missions, such as the KH-11 Program. This technology uses a simple computer to process images through very advanced technology. The actual process is really quite simple.

A picture can be created straight from a physical scene such as a snapshot of the beach or a close-up of dew on a rose. This can be accomplished through traditional means, such as through side-scan sonar, scanners, printed paper, analog mediums or photographic rolls of film. It can also be retrieved from a mathematical or geometric equation that is process into the computer, which creates a picture. This is also known as “rendering” or “synthesis.”

This process is now commonly used in day-to-day activities within hospitals, government agencies and law enforcement, which employs it within field of forensic science, which uses scientific methods to work out problems that are plaguing the legal world. However, as much as this has been used on a more technical scale, it’s recently been used to procure medical information for common patients.

“In Vivo” means “within the living” in a language known as Latin. This process employs the previously noted technology and acts as a sort of “application” to it. By its definition we can see that it is used in the experimentation of live organisms in contained and controlled environments. This is particularly true when dealing with their skin.

This process allows scientists to retrieve pictures of the layers of skin tissue and darken them, lighten them, search deep inside for problems. It’s extremely helpful in the way that it provides not only research to scientists studying living beings, but doctors may be able to help an ailing patient by procuring otherwise unattainable information that could lead to his recovery.

In 1994, this technology was inducted straight into the “Space Foundation Technology Hall of Fame.” Not only is it used in pictures, but it’s also used in pattern recognition, feature extraction, signal analysis, classification and more. It uses partial differential equations and neural networks. The beauty of it is that it can be used on an extremely complex level, or the level of the average camera.

Nearly everyone can achieve some level of health benefit by participating in a regular practice of a variety of poses. The health benefits are often categorized as either physical or mental in nature, though one could say that some of these benefits fit both. Irrelevant of how it is labeled, the good news is that with a little time each week, you could start to see some of these benefits in your own life.

From the standpoint of flexibility, strength and balance, there is much to be gained. There are poses that are specifically designed to address each of these factors. Flexibility is improved by stretching your body in ways that you might not normally experience. A gentle twist is an example of a pose that stretches your body and improves your flexibility. It is especially useful for those areas of your body that tend to hold tightness, like your shoulders, back and hips. Improved flexibility can help preserve range of motion and prevent injury.

Many poses force you to support your body in ways that are different than anything you have tried before. For example, the plank pose has the bulk of your weight supported by your arms, as only your hands and toes are touching the mat, while the rest of your body is attempting to be straight and level as a plank of wood. This is good for strengthening your arms, your back, your abdominal core, as well as your legs. It might look easy, but if done correctly you will really feel the effects of the plank position.

As you age, one of the most important factors to staying healthy is balance. Without it, you are at risk for a fall that can be a serious health risk. Improving your strength and flexibility will naturally aid you in balance. Couple that with specific balance poses, like the tree pose, where you balance on one leg, and you will begin to see an improvement in your body’s balance.

Another benefit associated with improved strength and flexibility is that it can help prevent back pain, or reduce it if you already experience this most common pain complaint. As you gain flexibility and strength, you gain awareness of your body positioning and alignment. This awareness helps you with how you carry your body, how you sit, and how you stand, often leading to a reduction in your back pain. If you are lucky enough to not have back pain already, this can help you prevent its onset.

There are a multitude of other potential physical benefits to a regular practice of your poses. Some that are mentioned in studies include overall fitness, improved muscle tone, maintaining a healthy weight, or possibly losing weight. By practicing special breathing exercises, called Pranayama, you learn to focus on your breath, and filling and emptying your lungs to the point that you have an increased awareness of your body’s use of breath. There are some who have achieved an improvement in their asthma symptoms by using these techniques.

Probably the biggest mental health benefit of your practice can be stress relief and management. While considered part of your mental health, managing your stress levels can also have a dramatic impact on your physical well-being. There is a strong relationship between stress and physical ailments. Through your practice you gain a calmness of your mind because of the concentration required to complete the poses. It is well known that physical activity can help reduce stress, but this level of concentration magnifies that benefit by pushing your stressful thoughts out of your mind as you focus on your poses.

Before starting any new exercise regimen, it is important to make sure you are healthy enough for the activity. If you have any doubts, see your physician before you start. With all the possible health benefits, there is a very strong likelihood that you can achieve some level of improvement from practicing yoga, no matter what kind of condition you are in today.
