 GLUDEAL AIRWAY ( oropharyngeal airway )

An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used in airway management to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway.


Insertion

OP airways in varying sizes

The correct size OPA is chosen by measuring from the first incisors to the angle of the jaw. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured. An alternative method for insertion, the method that is recommended for OPA use in children and infants, involves holding the tongue forward with a tongue depressor and inserting the airway right side up.

The device is removed when the person regains swallow reflex and can protect their own airway, or it is substituted for an advanced airway. It is removed simply by pulling on it without rotation.

Usage

Use of an OPA does not remove the need for the recovery position and ongoing assessment of the airway and it does not prevent obstruction by liquids (blood, saliva, food, cerebrospinal fluid) or the closing of the glottis. It can, however, facilitate ventilation during CPR (cardiopulmonary resuscitation) and for persons with a large tongue

All you need to know about the benefits of organic foods The word “organic” has taken the community of modern Indian parents by a storm, and there’s a reason for it. For years, we have known that the crops, vegetables and fruits bought at the marketplace are mostly grown with the help of fertilisers and pesticides. Today, we can do something different. We can opt for food that is grown without the harmful chemicals and pesticides. That’s where the organic food story begins. Hence, organic foods, which once belonged only on the shelves of premium health stores, have now moved into general supermarkets. Now, conventionally grown foods might give your kid the same amount of macro and micronutrients as organically grown ones. However, they do have a big difference. So, are organic foods healthier?

What are gallstones?

What are gallstones? Gallstones  begin with bile, a substance that helps with the digestion of fats and the absorption of certain vitamins. Bile is made in the liver and carried to the gallbladder, a small, pear-shaped organ that concentrates and stores it. The fat in food triggers the release of a hormone that causes the gallbladder to contract and release bile into the intestine. Gallstones are solid lumps that develop when the stored bile crystallizes. Most are less than an inch in diameter, but they can be as small as a grain of sand or as large as a golf ball. Most gallstones are composed mainly of cholesterol. The rest known as pigment stones  are made of calcium salts and bilirubin, a breakdown product of red blood cells. Cholesterol stones form when liquid bile in the gallbladder contains more cholesterol than the bile salts can dissolve. Cholesterol stones may also develop if the gallbladder doesn't contract and empty as it should. Pigment stones are a...
