Surgical procedures involved in ‘fitting’ adult lungs in the child
In case, one or both lungs are affected by an infection where a lung transplant is carried out to replace the diseased lungs with healthy ones. Lungs which are used for transplantation are donated from people who are about died and had decided to donate their organs before their death. To make adult lungs fit a child, two procedural ways are followed. One of the ways involves trimming off the pieces of the lung that makes it match the size of the chest cavity of the child. In the second procedure, where the adult lungs are compared to the child, a small portion of the lung from the adult is used. This portion is referred as a lobe which is then used during transplant. (Orens, 2006).
The lungs from the recipient must be free from diseases such as pneumonia so that they do not cause complications during and after surgery. Other clinical procedures such as testing the blood groups of the donor and the recipient are carried out to reduce cases of rejection. Other clinical procedures that carried out includes diagnostic tests which are carried out to check the health of the patient. Sarah who undergone lung surgery received her lung from an adult hence the doctors preferred trimming the lung. It was the simplest way so as the lungs can fit in her chest. Several surgeons are involved in the process of lung transplant should take a short period as possible. The surgery was smoothly done as per the recommendations of the doctor who operated her as well as prove from her family that she is recovering exceptionally well (Higenbottam, 1988).
Mechanics of breathing, with respiratory structures Sarah will use to breathe using respiratory chapter 23a and 23b
Breathing is a mechanism that involves several integrated aspects. Breathing mechanism is an automatic mechanism in that the lungs and diaphragm contracts and relaxes without any stimulation. Mechanics of breathing first includes actions which are specific which occurs in the skeletal muscles. The skeletal muscles which are involved with this procedure are the muscles that are involved in breathing such as the internal and external intercostal muscles. The second mechanic of breathing is that the volume of the thoracic cavity changes. In case of breathing out, the size of the thoracic cavity decreases. On the other side, during breathing in the volume of the thoracic cavity increases. It significantly gives room for the lungs to contract as well as relax simultaneously.
The third process of breathing involves the changing of the pressure in the thoracic cavity in response to the changes in the volume of the lungs. The changes of decrease or increase in pressure in the thoracic cavity are based on the Boyles’s gas law. When the volume of the thoracic cavity increases, pressure decreases hence air is forced to enter into the lungs. When the volume of the thoracic cavity decreases, pressure increases, thus air is expelled out of the lungs. The forth mechanic involves pressure gradients which takes place in the thoracic cavity (Christie, 2010). Additionally, the fifth procedure involves changes in volume and pressure which are directly associated with the process of breathing. During and after the surgery, Sarah used life supporting machines which work as close to what lungs does by providing enough oxygen to all body parts as well as to remove toxic substances primarily from the body cells such as carbon (IV) oxide, which if left to accumulate would cause rapid death of the cells.
The success rate for her surgery and how it is done todayThe success rate of lung transplant depends on the center where the operation was carried out. In most experienced centers, the chances that death will occur within the first thirty days of transplant is as low as five percent translating that after the successful operation has been carried out, there are high chances of survival. The survival rate of one year lies between eighty to ninety percent with much dependence on the how the company is experienced. How complicated the condition is in a patient is directly related to the survival rate. Half of the patients who undergoes lung transplant live for about five years while a third of the patients make it to ten years.
In recent days, a lung transplant technology has continuously been improved making the process safer hence chances of survival are high. Many surgeons have been involved in the process of a lung transplant in many countries hence coming up with new ways of carrying out the process. The recent successful lung transplant which was carried out on Sarah in the United States is signified that the process is continued correctly than before where survival rate was low. Furthermore, a lung transplant is carried out in most experienced companies where success rates are continuously reported.

Lung cancer has been one of the deadliest diseases caused by excessive consumption of tobacco
Lung cancer has been one of the deadliest diseases caused by excessive consumption of tobacco. The government has responded to the rising levels of tobacco consumption by slapping a highly exploitative tax to both the tobacco farmer and the cigarette’s manufacturer. The question that stems out of this line of thinking aims at establishing a relationship between the rate of cigarette smoking and cigarette tax. For this research, we shall hypothesize that the higher the rate of cigarette taxation, the lower the smoking rates in the United States of America. The reasoning that leads to the development of this hypothesis is in accordance to the law of demand that states that, the higher the price of commodities the lower the consumption levels. Higher taxation levels are expected to increase the prices of the respective commodities. Some of the issues expected to shed some light on this topic include the impact of tobacco taxes and prices on the demand levels of cigarettes. This will be possible to access through the determination of a possible correlation between the two variables. Secondly, we shall use a measure of the proportion of individual income spent on the purchase of cigarettes. Previous studies have shown that a change in price leads to less than proportionate decline in the level of demand hence, the price elasticity of demand stands from -0.3 to -0,5. In this research, we shall determine the relationship between price and the level of cigarette demand.
Background
Ramsey’s rule holds that consumption taxes should be applied to those goods that enjoy low price elasticity. The major reason for this is to allow for minimization of the welfare losses associated with the taxation of such goods. In the recent past, many countries have moved to increase tobacco tax to reduce the levels of tobacco consumption. A good example is the United States where the welfare loss associated with tobacco far much outweighs the benefits that are associated with it. The agenda of the increased costs is that, the tobacco users should bear the full costs associated with the consumption of tobacco. However, they assume that the social costs arising can be quantified in monetary terms and their equivalents determined. A major topic that relates heavily to this topic is the use of tobacco tax as part of the public health policy. This is supported strongly by the externality costs that come along with the use of tobacco. However, this research aims at establishing the impacts of the taxes on the tobacco.
The history of cigarette smoking
In the United States, one can say that tobacco tax is much older than tobacco smoking. This is in the light that, tobacco law was developed out of the development of tobacco products such as snuff back in the late 18th century. It was not until mid-19th century that cigarette smoking became popular among the citizens. Alexander Hamilton introduced the first tobacco law in 1794 as the secretary to the treasury. The introduction of this law on tobacco products was successful as many amendments. It composed of major modifications that were repealed after it was realized that they had minimal impact on the federal budget. Despite the failure of this law, Hamilton’s idea of tobacco taxation remained a major topic and subject to the history of tobacco taxation in the United States.
Almost a decade later, the House of Representatives passed a major law on many similar products among them, tobacco. The passing of this law was aimed at raising funds that would be used in debt servicing after the union had acquired increasing debts over time. The law, passed in July 1, 1862 could not last as a whole. Shortly after the civil war financing was over, most of the substances that had been passed alongside tobacco were repealed but incidentally, tobacco remained as one of the substances that had to be regulated by the law. The tax revenues emanating from tobacco taxation was the government’s main source of revenue in the year 1868.
The federal government was the only entity that had imposed an exercise tax on tobacco until the 20th century when Iowa became the first state to enact a law to exercise tax on tobacco. This new tax was in addition to the federal tax making the taxation of tobacco gain significant weight on the producers. By the year 1950, about 40 states had enacted legislation to levy taxes on tobacco. The entire United States and Columbia district had enacted tobacco tax by the year 1969. Several other cities had also put in place their own citywide cigarette tax that aimed at collecting tax for the jurisdictions. Among these cities, we have New York and Chicago among others. New York had the highest levels of tobacco tax in the entire United States with a $1.5 levy on the city tax and $4.55 rate on the state and local level. The state of Missouri had the least tobacco taxes listing 17cents, far below the list of many other countries.
