How can a simple checkup help reduce your chance of death? First of all, the respiratory system is made up of the different organ that are responsible for taking in oxygen and removing carbon dioxide from your system. A couple of the organs that make up the respiratory system is the nose, mouth, trachea, the bronchial tubes, and many others. Since the respiratory system plays an important part in the body, it is important to have your regular checkups. There are many reasons why to get a check-up, one of the reason may be because of respiratory problems. This can become a serious issue because the body needs oxygen to support itself. A lack of oxygen can lead to brain damage or even death. Another reason to have a regular checkup is to if there …show more content…
Technology and physical examination used to assess the respiratory system has never been easy though, there have been many studies done to get to where we are today. Assessing the respiratory system can be as easy as asking a few questions or undergoing different test and examinations. A few of the questions a doctor might ask is what kind of exercise do you do, what do you eat, do you smoke, and/or does anyone in your family have any respiratory problems. Family history is taken into consideration because the patient could have inherited the problem. Another way to assess the respiratory system is through respiratory examination. Equipment that the doctor will use is a stethoscope and a pulse oximeter, which is used to measure the oxygen level in your blood. First, the doctor will count your respiratory rate. The normal breathing rate is about 12 to 20 breaths per minute for an adult (“Physical…”). They will also see if it's easy for you to breath or if you're having trouble. Next, the doctor will use the pulse oximeter to measure the oxygen saturation …show more content…
It’s easier to get a regular checkup than it is to get a late checkup and find out you’ve had cancer, and it could have been avoided just by getting a checkup before. Even though it took us many centuries to get to where we are not, does not mean we won’t discover something new later one. There are already many studies that are being done right now to prevent many diseases from starting. There could also be projects that are looking for a way to detect when a person will become severely ill and help us prevent it before it happens. We will just have to wait and see what our future will have in store for
Both tests are very useful for assessing the pulmonary and cardiac system health of the individual being examined. This involves examining the individual’s response to the test by assessing their BP, HR, oxygen intake abilities, and using this information to infer whether they have some type of internal impairment. This includes
Additionally, some of the general diagnostic and pulmonary function tests are distinct in emphysema in comparison to chronic bronchitis. In the case of R.S. the arterial blood gas (ABG) values are the following: pH=7.32, PaCO2= 60mm Hg, PaO2= 50 mm Hg, HCO3- = 80mEq/L. R.S.’s laboratory findings are indicative of chronic bronchitis, where the pH and PaO2 are decreased, whereas PaCO2 and HCO3- are increased, when compare to normal indices. Based on the arterial blood gas evaluation, the physician can deduce that the increased carbon dioxide is due to the airway obstruction displayed by the hypoventilation. Furthermore the excessive mucus production in chronic bronchitis hinders proper oxygenation leading to the hypoxia. On the other hand, in emphysema the arterial blood gas values would include a low to normal PaCO2 and only a slight decrease in PaO2 which tend to occur in the later disease stages.
The respiratory system undeniably serves a very important function in the body. Anyone who has had any event where they couldn’t breathe normally, or maybe not at all, recognizes the importance and mental peace that comes with being able to breathe stress free.
Ascertaining the adequacy of gaseous exchange is the major purpose of the respiratory assessment. The components of respiratory assessment comprises of rate, rhythm, quality of breathing, degree of effort, cough, skin colour, deformities and mental status (Moore, 2007). RR is a primary indicator among other components that assists health professionals to record the baseline findings of current ventilatory functions and to identify physiological respiratory deterioration. For instance, increased RR (tachypnoea) and tidal volume indicate the body’s attempt to correct hypoxaemia and hypercapnia (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). The inclusive use of a respiratory assessment on a patient could lead to numerous potential benefits. Firstly, initial findings of respiratory assessment reveals baseline data of patient’s respiratory functions. Secondly, if the patient is on respiratory medication such as salbutamol and ipratropium bromide, the respiratory assessment enables nurses to measure the effectiveness of medications and patient’s compliance towards those medications (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). Thirdly, it facilitates early identification of respiratory complications and it has the potential to reduce the risk of significant clinical
As the author highlighted in this book, the quickest way to be diagnosed for prostate cancer is to be screened for it; the same notion applies for many other diseases and illness. With the advent of the technological age, doctors are now able to see more than they did before, and therefore, are more quick to diagnose illnesses and cancers early. As Welch explains, the problem with that is that not all illness or cancers will kill you; some cancers will stick around, but never cause any harm. So, this leads to screening for cancers that were never going to kill a patient, that end up being detected early on and dealt with, thus giving credit to early screening as a success story. As Welch explains, most illnesses and injuries that undertake a natural course of events, without medical intervention, usually heal on their own. This is problematic because it creates this idea that medical intervention is helpful and necessary, when that is not always the case. In general, as a society, the benefits of medical care have been over-exaggerated, while the harms of medical care have been largely ignored. If Welchs’ instructions were followed, a closer examination of the effect of screenings and tests would be the new medical
The ability to carry out and document a full respiratory and cardiovascular assessment is an essential skill. The severity of illness can be initially evaluated by inspection, palpation, percussion, and auscultation. During analysis, specific locations of symptoms can be identified using landmarks such as the midaxiallary, midclavicular, and, the midsternal line. Indicate anterior or posterior thorax, and use the midaxillary line location when applicable (Bickley & Szilagyi, 2013).
An electrocardiogram (ECG) is one of the primary assessments concluded on patients who are believed to be suffering from cardiac complications. It involves a series of leads attached to the patient which measure the electrical activity of the heart and can be used to detect abnormalities in the heart function. The ECG is virtually always permanently abnormal after an acute myocardial infarction (Julian, Cowan & Mclenachan, 2005). Julies ECG showed an ST segment elevation which is the earliest indication that a myocardial infarction had in fact taken place. The Resuscitation Council (2006) recommends that clinical staff use a systematic approach when assessing and treating an acutely ill patient. Therefore the ABCDE framework would be used to assess Julie. This stands for airways, breathing, circulation, disability and elimination. On admission to A&E staff introduced themselves to Julie and asked her a series of questions about what had happened to which she responded. As she was able to communicate effectively this indicates that her airways are patent. Julie looked extremely pale and short of breath and frequently complained about a feeling of heaviness which radiated from her chest to her left arm. The nurses sat Julie in an upright in order to assess her breathing. The rate of respiration will vary with age and gender. For a healthy adult, respiratory rate of 12-18 breaths per minute is considered to be normal (Blows, 2001). High rates, and especially increasing rates, are markers of illness and a warning that the patient may suddenly deteriorate. Julie’s respiratory rates were recorded to be 21 breaths per minute and regular which can be described as tachypnoea. Julies chest wall appeared to expand equally and symmetrical on each side with each breath taken. Julies SP02 levels which are an estimation of oxygen
Cancer has been an active concern in our society for the past couple decades, since we truly discovered the nature of cancer and the potency it brings along with it. However, it was not until the mid-20th century that scientists were beginning to truly understand the origin of cancer. Scientists dating back all the way to the Renaissance, when they first began performing autopsies to learn more about the human body and form, noticed abnormalities but it never clicked that it was something much worse than it seemed. Research has continued since then, and it has continued to thrive even to this day. When James Watson and Francis Crick discovered DNA and it’s chemical structure in 1962, it opened up doors that even they could not expect. With the understanding of DNA and how it affected the way we look at life, came the beginning of the understanding of mutated DNA (which is a cause of the growth of cancerous cells). In this past century, researching scientists discovered that cancer is linked with the DNA that resides in a cell’s nucleus. By ways of damage to the cells via chemicals or radiation, or even introduction of a new DNA, the cancerous cells begin to form and duplicate. We are learning more and more about cancer and how to fight it, but we still have much more to learn.
Doctors may use a physical exam to diagnose asthma; they’ll listen to the lungs of the patient who was experiencing asthma symptoms with the use of a stethoscope. A chest x-ray could be used as well to determine the diagnoses by ruling out other lung diseases. The allergy test can also diagnose asthma because of the skin prick test which can determine what allergens could make the asthma symptoms worse or the ones that can trigger the asthma. Lastly, a blood test could also be useful in determining if they have asthma. In Mr. TG case, the results of his tests would determine that he does have asthma.
Continue by giving two slow breaths, one to one and a half seconds per breath. Watch for the chest to rise, and allow for exhalation between breaths. Check for a pulse. The carotid artery, on the side of the neck, is the easiest and most accessible. If breathing remains absent, but a pulse is present, provide rescue breathing, rescue breathing is one breath every three seconds.
A diagnosis is the first step in coming terms with effective asthma treatments. One way to test for asthma is a physical exam, which is where health professionals ask questions about signs and symptoms, and other possible health issues. Lung function tests can determine the amount of air that moves in and out as you breathe. (Mayo Clinic) Spirometry is another process that estimates the narrowing of bronchial tubes by checking how much air an individual can exhale after a deep breath and how fast the patient breathes out. Peak flow meters are a common test procedure for asthma.1 The peak flow meter is a device that measures how hard you breathe out or exhale. Lower readings on the meter shows a diminished lung capacity resulting in less effective breathing. It is generally a strong signal that an individual's asthma may be getting worse.2 These measurements are taken again after the use of bronchodilators such as Albuterol to open your airways. If the inhaler impr...
We now can find what specific cancer a patient has and where, and give them a variety of treatment options such as surgery, chemotherapy, radiation, and several other types of treatment including experimental drugs. But there is no 100% guarantee that these treatments work. Ancient physicians and surgeons knew that cancer usually came back after it was removed surgically and recognized that there was no cure once the cancer had spread, and thought that intervention may be more harmful that no treatment at all. Some people today still think of cancer as incurable and wait until the last minute to go to the doctor. Galen was a 2nd- century Greek doctor that claimed a breast cancer tumor could be completely removed if it was caught at an early enough
But, what are we doing about it? Do we have the technology to finally be able to put this deadly disease to an end? During the 15th century, scientists started grasping a better understanding of the human body. Giovanni Morgangi was the first to perform autopsies on patients to relate to their illnesses along with the finding of cancer after death. This laid the foundation of scientific oncology, the study of cancer.
There are 2 types of breathing, costal and diaphragmatic breathing (Berman, 2015). Costal refers to the intercostal and accessory muscles while diaphragmatic refers to breathing using your diaphragm (Berman, 2015).It is important to understand the two different types of breathing because it is vital in the assessment of the patient. For example, if a patient is suing their accessory muscles to aid in breathing then we can safely assume that they are having breathing problems and use a focused assessment of their respiration. Assessing respiration is fairly straightforward. The patient’s respiration rate can be affected by anxiety so a useful to avoid this is to check pulse first and after you have finished that, while still holding their pulse point, check their respiration rate. Inconspicuous assessment avoids the patient changing their breathing because they know they are being assessed which patients can sometimes do subconsciously. Through textbooks and practical classes I have learned what to be aware of while assessing a patient’s respiratory rate. For example; their normal breathing pattern, if and how their health problems are affecting their breathing, any medications that could affect their respiratory rate and also the rate, depth, rhythm and quality of their breathing (Berman, 2015). The only problem I found while assessing respiration rate was I thought it seemed a bit invasive looking at the
Patient will display adequate gas exchange as evidence by SaO2 values and respiratory rate consistent with baseline.
