Oxygen therapy for COPD is more than 60-70 years old. In this long period, a vast amount of knowledge has been gained of the advantages and dangers of the same. Newer ideas, experiments, and their evaluation is part of any scientific endeavor and oxygen therapy is the newest technique that aims at giving air enriched with oxygen to breath. One type is exertion induced COPD. Oxygen enriched air is to be breathed in only during the exercise. This is seen to increase endurance and efficacy of exercise. This helps patients to maintain or even improve their physical fitness improving the COPD also. The real need of long-term oxygen therapy is for those suffering chronic oxygen deficiency in their blood. The condition is called chronic hypoxemia or hypoxia. Long-term oxygen treatment will improve the quality of life and also lifespan. One suffers less shortness of breath. It slows or even prevents Right Sided Heart Failure, which is the normal consequence of COPD. Oxygen therapy for chronic COPD is resorted to after normal medical treatments for COPD have ceased to benefit the patient. There are different ways to introduce the oxygen. Oxygen concentrators, liquid oxygen devices and the more conventional oxygen cylinders can all be used to augment the oxygen into the air that is breathed. However, people who use oxygen therapy at home should be well aware of the dangers of oxygen. Even air enriched to seemingly low levels of 28% can cause conflagrations of unbelievable intensity. Any fuel will spontaneously catch fire in air that is of this level of enrichment. Portable systems even suitable for air travel are also available. Studies have shown that long term oxygen therapy (LTOT) improves one's life quality as well as lifespan. Patients need to breath the enriched air for at least 15 hours a day with as less interruptions as possible, and preferably continuously. The oxygen level in the blood is to be maintained in a narrow band of 88% to 92% saturation (titrated flow) against normal levels of 94% to 98%. To overcome the dangers of hypoxemia, the best thing to do is to use the pulse oximetry set to titrate oxygen delivery to achieve 88-92% saturation, a venturi mask' (or an air-entrainment mask) setting oxygen concentration to 25% to 28% concentration or in the absence of any of the above, a flow rate of oxygen by nasal prongs or catheter can be set 2 to 3 L/min. Modern research has shown better efficacy of delivering bronchodilator with a flow rate of 6L/min in acute exacerbation of COPD. The medical personnel should monitor the patient for complications of hypoxemia like carbon dioxide retention.

The world would be less interesting if everything in it didn't have a story about it. These stories or legends have a certain appeal to it. Once you are familiar with it, you would start seeing the object in a different light altogether. These stories would give you an insight into what makes it what it is!

Even your food and beverages have ancestors you can trace it back to. When you are sitting in a bar and sipping on some margarita, did you ever give it a thought about how it originated? Well, everything evolves and your favorite drink too has evolved. What was a simple margarita back then has been modified and now when you surf the internet for various margarita recipes, the list is endless.

The origins of margarita is a bit murky as there are many stories behind it. One such popular belief is that it was invented by Carlos Danny Herrera at his restaurant Rancho La Gloria near Mexico. He had created this drink for the vivacious Ziegfeld dancer, Marjorie King. The story states that Ms. King was allergic to all sorts of spirits other than tequila. So, Herrera tried making a special drink for his customer with tequila, lime, and some salt. And this is the recipe of the first ever margarita.

The second popular story is quite different. According to it, it was not some bartender who came up with the margarita recipe. Instead, it was a Texas socialite, Margaret Sames a.k.a Margarita Sames. It is believed that she had randomly mixed some spirits together and concocted this widely popular drink. However, if you wish to have a professional opinion, then the famous cocktail historian David Wondrich has something to say. After much research, he came to the conclusion that the margarita has evolved from a cocktail called daisy. Daisy was a mixture of citrus juice, alcohol and grenadine served with shaved ice. After a period of time, the Mexican tequila daisies became popularly known by its Spanish name margarita.

There are a lot of assumptions about how the famous drink came into existence and these stories give you something to ponder on. If you wish to try your hand at making the original margarita, pour some tequila, Cointreau and lime juice in a cocktail shaker with some ice and shake it vigorously. Strain the drink into a martini glass and soak half the rim in water and half of it in salt. Add a lemon wedge on the rim and there, your original margarita is ready to serve. You can look up different margarita recipes on the internet and become a savvy bartender at your house parties!

You want to rock that beautiful backless dress for a friend's wedding or that summer barbeque or simply wear it for a stroll in the park on a beautiful summer day. What is stopping you is back acne, more commonly known as bacne! Here are some ways to help get rid of bacne and prevent it from coming back. Causes Bacne could be due to many reasons like oil glands, genetics, stress, diet hormones, etc. It can be due to pore clogging thanks to workout sessions or the case of conditioner from your hair sticking to your back, bag straps or even unwashed bras straps. Treatment While you can always go to the dermatologist for quick solutions like an antibiotic or a topical treatment, there are some bath and body products you can try too. Look for products with salicylic acid and benzoyl peroxide. These are common acne-fighting ingredients. Salicylic acid helps in exfoliating and removing dead skin while benzoyl peroxide kills the bacteria that causes acne. Body washes: There's a range of bath and body products you can choose to fight bacne. Try a body wash with benzoyl peroxide. Try choosing a mild formula like so that the skin doesn't get dried out even if you decide to shower more than twice a day. Example, Clean & Clear Continuous Control Acne Cleanser. Moisturizer: Another bath and body product to consider is moisturizer. Yes, your back needs to be moisturized too. Look for products that 'oil-free' and 'non comedogenic. Like Philosophy Clear Days Ahead Oil-Free Salicylic Acne Treatment & Moisturizer. Exfoliator: Exfoliating is an important step when it comes to treating acne. It is important to remove dead skin cells, improve circulation and encourage generation of new skin cells. However, avoid scrubbing too much. Try the Neutrogena Body Clear Body Wash in Pink Grapefruit. Keep cool: Another way to treat bacne would be by keeping cool temperatures at night so that you don't sweat while sleeping and to wear loose cotton clothes while in bed so that your skin breathes. Deal with the scar: Acne can leave blemishes and scars on your skin. To get rid of the scars, you could always try a concealer. Vitamin E oil however, is a great way to get rid of scar and encourage formation of new skin cells. You can also opt for a chemical peel that will gently exfoliate the skin to reveal better looking, blemish free skin. But you might want to try that out after consulting with a dermatologist. Sunscreen products: Once you have gotten rid of bacne, maintain healthy skin by adding sunscreen to your routine, especially, if you tend to wear outfits that exposes your back a lot. Look for a light, oil-free formula that wont clog your pores. Look for a gel-like formula with vitamin C to keep inflammation at bay. In the meantime, keep stress levels in check, shower as soon as you exercise and rinse your back after you condition your hair to prevent bacne from recurring.
