Chlorofluorocarbon Pros And Cons

Bronchodilators also help patients with COPD. While this class of medication does not treat the underlying cause of the symptoms, the unruly inflammatory response, they do relieve problematic symptoms of the condition. Beta¬2-adrenergic agonists work to relieve acute bronchospasms by activations beta 2 receptors on smooth muscles. As the smooth muscle relaxes bronchodilation occurs and relief of the bronchospasm follows. Beta 2 agonist can be long or short acting and can be administered orally or inhaled. The short acting medications (SABA)are used to control acute attacks and are generally employed for quick relief of an ongoing attack. Long attacking agonist (LABA) are taking as a prophylaxis medication to stop the attack from happening before

When an asthmatic takes an inhaler “Albuterol sulfate”, the medication works by reducing the inflammation in the airway paths “bronchi and bronchioles” of the lungs, allowing the patient to breath without constriction or symptoms of asthma.

It is one of the most popular and portable forms of asthma medication. I have been using this type of inhaler as my primary means of receiving both daily medication and fast-acting “rescue” medication to manage my asthma for six years. I cannot exercise, spend time outdoors, clean or take part in many activates without taking both a daily medication inhaler and frequently a rescue inhaler several times during the activity. There is nothing like the relief of an inhaler when you cannot get in a breath or are coughing so hard your chest hurts. All three of my previous jobs and all of my hobbies are activities that cause me to experience asthma symptoms and I would not be the person I am today if I did not have those experiences. There are so many things I enjoy such as hiking, fencing and horseback riding that I would be unable to participate in at all if it were not for this life-changing invention. The inhaler has saved my life and allowed me to live a normal, active and healthy lifestyle. The inhaler is the topic of this paper because it has made a significant impact on my life and without this invention my world and life would be vastly

Perfluorocarbons (PFCs) are lab made chemical compounds that are linear and cyclic hydrocarbons who have a low molecular weight. Liquid Perfluorocarbons are formed when hydrogen ions in hydrocarbons have been replaced with fluorine atoms since they are neutral chemical compounds (Veni et al. 39). Perfluorocarbons are also chemically inert—not chemically reactive—due to the strength of the carbon-fluorine bonds (Anilkumar et al. 478). Perfluorocarbons are made into Perfluorocarbon artificial blood by adding water, salt and phospholipid surfactants to it, then the solution is then emulsified through high pressure homogenization—when two non-soluble liquids are turned into an emulsion—the solutions is then purified through a high temperature

Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. This means, that this inhaler helps you to breathe when you are experiencing troubles breathing from asthma symptoms.

It looks exactly like your typical inhaler. It performs in the the same way too, but without the albuterol.

Stevens, the dose should not be more than 2mg up to 4 times a day. This dose may be slowly increased, up to 32mg per day. The purpose of Albuterol is to dilate the bronchioles and prevent airway obstruction caused by the COPD. Due to its adrenergic properties, common side effects include nervousness, restlessness, tremor, headache, chest pain, and palpitations. Excessive use of inhalers could result in paradoxical bronchospasm. Albuterol binds to adrenergic receptors which lead to increased levels of cAMP. Kinases are activated by cAMP, inhibit the phosphorylation of myosin, and decrease intracellular calcium; intracellular calcium relaxes the smooth muscle airways. The nurse should assess the lung sounds, pulse and blood pressure before administering albuterol, and should be aware that nebulized forms of the medication may result in temporary low levels of potassium. Pulmonary function tests should be monitored prior to and during treatment. Mr. Stevens should prime the unit with four sprays before using, and should contact his primary care physician if shortness of breath is not relieved, or it is joined by diaphoresis, palpitations, dizziness, or chest pain. Mr. Stevens should also discard his canister after 200 sprays (Vallerand, 116).

ProAir® RespiClick (albuterol sulfate) is a dry powder inhaler that has no spray. Medication delivery is “breath-activated,” which reduces the need for hand-breath coordination during inhalation. Instead, you CLICK and inhale the measured dose of medicine (22)

Inhalants can be used in many different ways. The way that they are used depends on the type of inhalant. They can be “snorted”, or

Which that needs a healthy way of coughing practices and airway clearance techniques in the lungs. More further, a patient with CF need to take vitamins to treat intestinal blockage. Also, eating high fat food and drinking nutritional drinks helps replacing lost nutrients. However, in some cases a patient may needs to get fed through a tube in the stomach or even he may needs a surgery to a chest tube drainage to treat a collapsed lung. So obviously, a patient needs to take a mix of medicines to control his body and this disease, such as tobramycin, albuterol, hypertonic saline, cromolyn, prednisone, and pancreaze. Where tobramycin works as antibiotic to treat and control infections, and albuterol helps opening the airways in the lung to make it easier to breathe. Hypertonic function is to thin and clear mucus from airways in the lung and intestines. Moreover, cromolyn uses as a factor targets inhabitation of inflaming. Prednisone organizes steroids and fat in the body, and pancreaze uses as a digestive

The ozone should always stay in tact to protects the earth from UV radiation, which is harmful to humans (skin cancer) and also the earth (global warming). If allowed to build up indoors, VOCs often contribute to lightheadedness, headaches, allergies and more importantly has also scientifically proven harmful to asthma sufferers. As a matter of fact, according to Professor Roy Harrison, professor of environmental health at Birmingham University, there is a body of research on VOCs in the indoor environment which links them with those kinds of symptoms - headaches and not feeling so good (news.bbc.co.uk). After proven to have negative effects on the ozone layer as well as humans, the production of CFCs was shut down and in fact it’s banned in the US. Some scientists were not convinced by the act of banning CFCs in spite of all these evidences. “Given the large economic impact of a ban — it was estimated that industries relying on CFC production generated $8 billion in business and employed 200,000 people in 1974 — several scientists in the field advocated waiting a few years for science to make more progress on the issue before making any policy decisions.” (bio.sunyorange.edu)

How do CFCs or chlorofluorocarbons affect Canada’s Ozone layer. To answer this question we first have to understand chlorofluorocarbons and the earth's ozone layer. Chlorofluorocarbons are chemical compounds made up of three chlorine atoms. One fluorine atom and 1 carbon atom. There were many uses for CFCs ranging from, being used as coolants in refrigerants to propellants for aerosols to being used as solvents for dry cleaning. As CFCs are non- flammable and not very toxic we thought they were a revolutionary compound, but unfortunately CFCs were one of the leading causes for the depletion of our ozone layer. ozone is a type of oxygen, an ozone molecule consists of three oxygen atoms whereas a regular oxygen molecule only consists of two.

Scientists all over the world have been widely researching to find out ways in which the ozone layer is being destroyed through human actions. The ozone layer is gradually being destroyed by ozone depleting chemicals. These chemicals include chlorofluorocarbons (CFCs), hydroflourocarbons (HFCs), methyl bromide, halons, methyl chloroform and carbon tetrachloride among others (Ryding 173). These chemicals are used locally in coolants, fire extinguishers, solvents, pesticides, aerosol propellants and foaming agents.

Chlorofluorocarbons (CFC’s): CFC’s are lowering the average concentration of ozone in the stratosphere. “Since 1978 the use of CFC’s in aerosol cans has been banned in the United States, Canada and most Scandinavian countries. Aerosols are still used around the world and accounts for 25% of global CFC’s use”. (Miller 448). Spray cans discarded or leaking refrigerator and air conditioning equipment and the burning plastic foam products release the CFC’s into the atmosphere. Depending on the type, CFC’s stay in the atmosphere from 22 to 111 years.” Chlorofluorocarbons move up to the stratosphere gradually over several decades. Under high energy ultra violet (UV) radiation break them down and release chlorine atoms, which speed up the breakdown of ozone (O3) into oxygen (O2). Chlorofluorocarbons, also known as Freons, are green house gas that contributes to global warming. Photochemical air pollution is commonly referred to as “smog”. Smog is the contraction of the words smoke and fog, smog has been caused by water condensing on smoke particles, usually from burning coal. With the introduction of petroleum to replace coal economies in countries, photochemical smog has become predominant in many cities, which are located in sunny warm and dry climates with many motor vehicles.
