How Pulse Oximeters Work Explained Simply.

Introduction
Pulse oximeters measure how much of the hemoglobin in blood is carrying oxygen (oxygen saturation).

If you work in healthcare (or have been patient !) you are very likely to have come across pulse oximeters. You can find them in areas such as operating rooms, recovery, critical care, wards, and ambulances.

Pulse oximeters are in common use because they are:
• non invasive
• cheap to buy and use
• can be very compact
• detects hypoxaemia earlier than you using your eyes to see cyanosis.

Oxygen Saturation
Pulse oximeters measure oxygen saturation. Before we learn the principles of how pulse oximeters work, we need to have an understanding of what oxygen saturation is.

We all know that we need oxygen for life. ( Some of you may find this section a little too basic. In that case, to skip this short section, click this link to go to next section Physical properties used in pulse oximetry)

Oxygen enters the lungs and then is passed on into blood. The blood carries the oxygen to the various organs in our body. The main way oxygen is carried in our blood is by means of hemoglobin. You can imagine hemoglobin molecules( Hb) as “cars” and the “roads” being our blood vessels. The oxygen molecules get into these cars and travel around the body till they reach their destination.

Physical properties used in pulse oximetry
Pulse oximetry uses light to work out oxygen saturation. Light is emitted from light sources which goes across the pulse oximeter probe and reaches the light detector.

If a finger is placed in between the light source and the light detector, the light will now have to pass through the finger to reach the detector. Part of the light will be absorbed by the finger and the part not absorbed reaches the light detector.

The amount of light that is absorbed by the finger depends on many physical properties and these properties are used by the pulse oximeter to calculate the oxygen saturation.

The amount of light absorbed depends on the following:
1. concentration of the light absorbing substance.
2. length of the light path in the absorbing substance
3. oxyhemoglobin and deoxyhemoglobin absorbs red and infrared light differently

Don’t worry ! All the above will be explained in the next sections:

The physical properties that a pulse oximeter employs will be explained using the probe shown below. A finger is shown inserted into the probe. Above the finger are the light sources that emit light. In the finger is an artery which carries the blood the pulse oximeter is interested in and a vein through which the blood leaves the finger. Below the finger is the light detector.

8 Supplements That Can Help Joint Pain

What Can I Do For My Joint Pain?
This is a common question I hear almost every day. Osteoarthritis, also known as degenerative joint disease, is very common in people especially over the age of 30.

The joints that are most commonly affected include the ones that take the most weight bearing and abuse such as the following:

• big toe
• knee
• hip joint
• spine

People who have sustained sports injuries are at greater risk of degeneration of the joint. Common every day activities do produce some wear and tear on the joints particularly if the body weight is increased. Even a 5 pound weight gain transmits five times which would equal 25 extra pounds of pressure to the lower body joints, so maintaining a normal body weight is very important.

Stretching and strengthening exercises are very important as they stabilize the joints. Since the tendons, joints and cartilage do not have any direct blood vessels, movement In the form of activity, specifically aerobic exercise that gets the heart rate up is important for diffusing both oxygen and nutrients into the joints.

Supplements and Medications To Help Joint Pain
1. Vitamin D
The number one supplement I recommend for joint health and overall musculoskeletal health is vitamin D3. Vitamin D is not a vitamin, but it is a pro steroid hormone. Humans can make vitamin D if they are exposed to the right ultraviolet light. However, most of my patients over age 50 are low in vitamin D (on blood testing with a 25-hydroxy vitamin D test). If you have joint pain consider starting 1,000 to 2,000 units of vitamin D per day and/or have your physician check your level.

2. Estrogen
Estrogen is important for musculoskeletal health, including joint health. There are estrogen receptors and cartilage and tendons. Postmenopausal women with low estrogen state may complain of joint pain and stiffness as their primary menopausal symptoms.
Low estrogen states can exacerbate tendinitis. Estrogen therapy is generally not given specifically for joint pain unless the woman is suffering from additional menopausal symptoms. There’s also evidence that women who undergo total joint replacements who are on post-menopausal estrogen do better than those not on hormone therapy. Talk to your women's health physician to see if estrogen is right for you.

3. Glucosamine and Chondroitin Sulfate
Glucosamine and chondroitin sulfate are one of the most common combination supplements that I recommend to women with joint pain, especially knee pain. Glucosamine has shown some protective benefit for knee arthritis in up to 70% of persons in divided doses of 1,000 to 1,500 mg per day.

The first time, I recommended the supplement several years ago I had a woman exclaimed, “That is what my veterinarian has me give my dog!” Dogs like other mammals do suffer from degenerative joint disease with aging.

Some studies have shown no benefit with glucosamine while others have shown reductions in joint pain - particularly the glucosamine sulfate salt. Various studies have shown the benefit of both glucosamine and chondrointin sulfate showing less pain and swelling and joint space narrowing, in doses of 800 to 1200 mg per day.

4. MSM
Methylsulfonlymethane (MSM) in doses of up to 6 g per day orally have been shown to reduce pain, improve function and reduce some stiffness. Long term studies aren’t available.

5. Turmeric
Turmeric is a spice containing curcumin, and taking 500 mg orally up to twice daily has been shown to have some anti-inflammatory, anti-oxidant, anti-cancer and perhaps anti-atherosclerotic effects. A side effect of turmeric can be increasing bleeding time, so patients on blood thinners and Coumadin need to be aware as well as some people who have G.I. distress.

6. Omega 3
Omega 3 fatty acids in doses of 2 to 4 g has been shown to reduce pain.

7. Ginger
Ginger is an herb that has anti-inflammatory, anti-cancer and anti-atherosclerotic effects and can be ingested, 3 g per day. Ginger is also used to treat nausea.

8. SAMe
S-adenosyl-L-methionine (SAMe) is a compound found naturally in the body.
A supplement form of SAMe has been used to help the liver, reduce joint pain and even elevate the mood.

Non-Drug Pain Management : Medvive TENS Unit

What is pain?
Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, pelvis, or you may feel pain all over.

There are two types of pain:

Acute pain usually comes on suddenly, because of a disease, injury, or inflammation. It can often be diagnosed and treated. It usually goes away, though sometimes it can turn into chronic pain.

Chronic pain lasts for a long time, and can cause severe problems

What are pain relievers?
Pain relievers are medicines that reduce or relieve pain. There are many different pain medicines, and each one has advantages and risks. Some are over-the-counter (OTC) medicines. Others are stronger medicines, which are available by prescription. The most powerful prescription pain relievers are opioids. They are very effective, but people who take them are at risk of addiction and overdose.

Because of the side effects and risks of pain relievers, you may want to try non-drug treatments first. And if you do need to take medicines, also doing some non-drug treatments may allow you to take a lower dose.

What are some non-drug treatments for pain?
There are many non-drug treatments that can help with pain. It is important to check with your health care provider before trying any of them:

Acupuncture involves stimulating acupuncture points. These are specific points on your body. There are different acupuncture methods. The most common one involves inserting thin needles through the skin. Others include using pressure, electrical stimulation, and heat. Acupuncture is based on the belief that qi (vital energy) flows through the body along paths, called meridians. Practitioners believe that stimulating the acupuncture points can rebalance the qi. Research suggests that acupuncture can help manage certain pain conditions.

Biofeedback techniques use electronic devices to measure body functions such as breathing and heart rate. This teaches you to be more aware of your body functions so you can learn to control them. For example, a biofeedback device may show you measurements of your muscle tension. By watching how these measurements change, you can become more aware of when your muscles are tense and learn to relax them. Biofeedback may help to control pain, including chronic headaches and back pain.

Electrical stimulation involves using a device to send a gentle electric current to your nerves or muscles. This can help treat pain by interrupting or blocking the pain signals. Types include
• Transcutaneous electrical stimulation (TENS)
• Implanted electric nerve stimulation
• Deep brain or spinal cord stimulation

Massage therapy is a treatment in which the soft tissues of the body are kneaded, rubbed, tapped, and stroked. Among other benefits, it may help people relax, and relieve stress and pain.
