Everyday amazing things happen in the human body. One of the things that happens is the way we take a breath, how we are able to use that breath to sustain life. As a breath is taken in, there’s many different physical and gas laws that take place to allow it to happen. With Hooke’s law I will be discussing what it is, how it relates to respiratory care, and the medical advances it may include.

ICU patients suffer from a broad range of pathologies, requiring MV, sedation and use of multiples devices, which do not allow patients to protect their airway (Augustyn. 2007; Kollef. 2004).

In conclusion, without the assistance of Poiseuille’s law, a patient with bronchial constriction would not get the adequate amount of oxygen to feed the tissues. Poiseuille’s law states that if the radius of a tube decreases by sixteen percent, the flow rate will decrease by half. In today’s modern medicine

Although when it happens, there can be a devastating impact on patients as well as to the multidisciplinary theatre team involved. Consequently, the DAS has produced a consensus set of guidelines for managing failed intubations in adult and paediatric patients, but there are as yet no such nationally-agreed guidelines in obstetrics, therefore each obstetric unit should have their own flowchart with regards to management of failed intubation (Brien and Conlon, 2013). Furthermore, in light of the latest DAS guidelines, several aspects of clinical anaesthetic practise have changed over recent years (Frerk at al, 2015). Amongst the changes are the use of new drugs such as rocuronium and suggamadex and using electronic video-laryngoscopes (Frerk et al, 2015). Further work had also looked at extending the period of apnoea without causing desaturation by optimising the preoxygenation process and adequate patient positioning (Frerk et al, 2015). As a result, updated guidelines for difficult intubations in adult patients were published in 2015; these guidelines provide a flowchart to be used when endotracheal intubation proves difficult or impossible and focus on the central importance of oxygenation while reducing the amount of airway interventions in order to minimize trauma to the delicate airway (Frerk et al, 2015). The main message of the revised guidelines is

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

I didn’t know what to expect with my observation with the respiratory therapist. All what I knew about them was they floated around and gave patients aerosol breathing treatments. I learned that a respiratory therapist does a lot more than that. They have access to the Pixis, and are able to give patients any type of respiratory medication. They teach patients how to correctly use inhalers. They educate their patients on way they have to do breathing treatments, or why they have to take certain respiratory medications. They also do an examination to find out what type of breathing treatment or oxygen device is needed to help a patient get the oxygen they need, or help with expanding their lungs, etc

The authors begin their initiation of the research article by stating their reason attention is needed to study the rate of accidental decannulation (AD). Due to the increment in the number of patients receiving protracted mechanical ventilation through artificial airway, much attention is needed to focus on how to reduce the morbidity and mortality rate of accidental decannulation. Not much recognition is given to the complications of AD compared to accidental extubation following translaryngeal intubation (White et al., 2012). According to the authors, the research was triggered by two sentinel events, hence a research for the identification of the causes of AD in LTACH and implementation of strategies to curb the situation.

Even though the consequence of saline instillation on a ventilator patient in the acute care setting is pneumonia or the patient may become hemodynamically unstable, this practice remain contentious, the practice of this procedure will also decrease the oxygenation. (Ayhan, et al., 2015),

By entering the field of respiratory therapy, one is entering a growing field of opportunity. There are continually emergent job opportunities in this field whereas there is also a rise of growth in the technology and developments in the field such as medicines, techniques, and other aspects.

Mr. Joseph is a 56-year-old has 30 smoking pack years. He was diagnosed 10 years ago with asthma/chronic bronchitis, arthritis of the knees, and congestive heart failure (CHF). Mr. Joseph weighs 350 pounds with a height of 6 feet, making his body mass index (BMI) of 47.5, much more than the recommended 25, and in fact his BMI places him in the morbid obesity classification. He takes medicines for his pulmonary conditions, along with a diuretic.

In the respiratory system, the mucus causes breathing difficulties, frequent respiratory infections and eventually permanent lung damage. The mucus builds up providing bacteria with a place to flourish. The most common infection comes from a bacterium called Pseudomonas aeruginosa. The body's response to P. aeruginosa includes inflammation, which causes episodes of intense breathing problems (Pseudomonas Genome Project, 1998). Normally the body will get rid of excess mucus by coughing before it's a problem but with the thick mucus involved in CF the body has a harder time to get rid of the thicker mucus. Lung disease is the usual cause of death in most patients (National Institutes of Health, 1995). In the digestive system, mucus can block the supply of enzymes used to break down food. The result of the blockage of such enzymes is malnutrition. The patient will have an excessive appetite but will not experience any weight gain. What is also evident is a failure to grow, CF was often misdiagnosed vaguely as "failure to thrive" when physicians didn't know the reason for this poor growth. Sweating is also a problem in people with CF. One of the basic defects in CF is the faulty transport of sodium and chloride (salt). People with CF lose excessive amounts of salt when they sweat. This causes the natural balance of salt in the body to be off balance, which may cause abnormal heart rhythms (National Institutes of Health, 1995).

Continuous Positive Airway Pressure or CPAP as it is known, uses forced air to keep a patients airway open. It has common uses that most people are familiar with such as sleep apnea. But it also used in emergency and hospitals routinely to treat sicknesses such as congestive heart failure. In this essay I will give a brief history on CPAP, a basic overview of its anatomy and the some of the many uses of CPAP and health benefits.

For the past 50 years acute respiratory distress syndrome or better known as ARDS, has been an issue in hospital intensive care units all around the world. The first “documented published scientific description dates back to 1821 when Laennec described the gross pathology of the heart and lungs and described idiopathic anasarca of the lungs; pulmonary edema without heart failure in a treatise on diseases of the chest.”1 Cardiac and non-cardiac issues were not taken into consideration as part of the cause at that time. The first definition dates back to Ashbaugh and colleagues in 1967.2 Though modern medicine has been around for hundreds of years, it wasn’t until hospitals designed intensive care units and began using mechanical ventilation

The respiratory system is the process responsible for the transportation and exchange of gases into and out of the human body. As we breath in, oxygen in the air containing oxygen is drawn into the lungs through a series of air pipes known as the airway and into the lungs. As air is drawn into the lungs and waste gas excreted, it passes through the airway, first through the mouth or nose and through the pharynx, larynx and windpipe – also known as the trachea. At this point it then enters the lungs through the bronchi before finally reaching the air sacs known as alveoli. Within the lungs, through a process known as diffusion, the oxygen is transferred to the blood stream through the alveoli (air ducts) where it is then transported inside
