Also, the paper will review literature on the effectiveness of the NIV treatment. Challenges on survival, Quality of life and compliance to NIV therapy According to the studies by Massimo, et al (2012, pp747), it was gathered that there are indications of early NIV positive pressure ventilation, which tend to increase the rate of survival. This was made in comparison with NIPPV. As such, NIV acts as a relief from challenges relating to survival rate in patients with high level of CO2 in their blood. A study by Pepin, et al (2008, pp360) indicates these challenges. According to the study, the challenges that these patients face are: fatigue, sleep patterns that are disturbed as well as breathlessness. The group also found out that NIV does not provide a prevention against weakening of the respiratory muscle that tend to progress. Acute exacerbations of a chronic Obstructive Pulmonary Disease better referred to as COPD, pose great challenge to the survival rate of a patient. In the periods that the patient is faced with worsening extremes, it adversely affects the patient’s health status. There is an escalating admission to hospitals and even rise of mortality rates (Angus, et al 2011, pp84). According to the studies by Fionnuala, et al (2007, pp60), it is approximated that the mortality rate of in-patient ranged from 4%-30%. The study goes on to indicate that patients that are admitted due to complications from acute Respiratory failure have a higher mortality rate. According to the study, the patients who are elderly and have co morbidities as well as those patients needing the ICU facilities were the most affected by the high mortality rate. According to the study by Monica, et al (2004, pp605), ventilation of the respiratory worsens to perfusion ratio and this result to a mechanism in the hypoxemia occurrence. This happens when psychological dead space enlarges. It also occurs when there is a rise in the ventilation waste. In the study by Suzy (2012, pp61), it was identified that increased resistance of the airway as well as the need for high minute ventilation tend to result to a limitation on the expiratory flow. Still, the study found out that a dynamic hyperinflation, enlarged threshold of the aspiratory load as well as respiratory muscle dysfunction result to a feeling of fatigue in a patient. Plant and Elliott (2003) studied that a rapid pattern of breathing, which is somehow shallow, occurs. This is due to the respiratory system efforts towards maintenance of enough ventilation in the alveoli. This happens when the elastic, resistive and loads of aspiratory threshold are introduced to the weakened muscles of the respiratory system. However, irrespective of an increment in stimulus of the centers of the respiratory system as well as swings in the large, negative intra-thoracic pressure, carbon dioxide is still retained and as such, acedemia occurs. Other studies by Rossi, et al (1995) and Ambrosino, et al (1997) established that severe COPD which is complicated by ARF, attain characteristics such as; right ventricular failure, encephalopathy as well as dyspnea and these pose as serious challenges to the survival of the patient. In regards to the studies by Eliott (2012, pp85), a vital intervening is advantageous to the patient with COPD is advisable. He suggested a clinical experience and this was an NIV treatment. Does NIV improve respiratory function or increase survival? A ...Download file to see next pagesRead More

...? a) What is the most likely explanation for this patient's change in mental status?  Introduction The most dominant causes of acute exacerbations of COPD entail overdose of drugs that suppress ventilator drive, as well as conditions that result to respiratory muscle weakness (Gay, 2004). Acute exacerbation of COPD represents an acute deteriorating of the patient’s baseline condition mainly characterized by dyspnea and enhanced volume and purulence of sputum. Depending on the severity of baseline COPD, further derangements can manifest, inclusive of hypoxemia, deteriorating hypercapnia with deteriorating lower extremity oedema, or altered mental status. The core goal in treating acute exacerbations of COPD centres on restoring... the...

A review of thirteen double-blinded randomized clinical trials, and eleven additional studies showed that COPD in patients taking inhaled corticosteroids have significantly fewer exacerbations. However, it was observed that there was a risk of cataract and open-angle glaucoma that was dose-related. The benefit of inhaled glucocorticoids was higher in patients with moderate to severe COPD, but no benefit was observed in individuals with mild COPD. Exercise is also a...

COPD

...COPD, an abbreviated word meaning chronic obstruction of the pulmonary disease is in itself a gradual disorder, disease that worsens with time. It is more often than not caused by cigarette smoking, either as a result of past history of heavy smoking or persistent act of the same. Among other causative factors like air pollutants and irritants, chemicals and dust particles, a cigarette smoking is the principal causing factor of COPD.There are awful consequences of this condition as it not only leads to serious mucous-coughs but also exhibits cut breath, tightening of the chest, and gasping of air, among other fatal conditions. To understand this condition, it is vital to revisit the mechanism of gaseous exchange as a...

...of air gets obstructed and hence unable to pass through the airflows often making such obstruction permanent. If patients suffering from asthma are not treated, then such patients tend to have a rigid element of obstruction of the airways leading to COPD. In COPD the limitation in the flow of air is progressive in nature. Moreover it leads to irregular inflammatory reaction of the lungs to lethal particles or harmful gases. The abnormal responses of the inflammations occur “throughout the proximal and peripheral airways, lung parenchyma, and pulmonary vasculature” (O’Connell Smeltzer et al, 2010, p.602). Since the inflammation is chronic in nature and there is a tendency of the body to...

I also comprehended the different levels of COPD and that taking a balanced diet is paramount in minimizing exacerbations. Moreover, it is important to receive pneumonia vaccines in every five years as well as influenza vaccine annually to avoid exacerbation. In addition, I learned that avoiding crowded areas during flu season and hand washing help to control infection. Lifestyle habits such as smoking affect the lungs causing COPD and the mouth leading to leukoplakia disorder (Shippee-Rice, Fetzer, & Long, 2012). I also comprehended that COPD patients can...

However, interacting long-acting Beta 2-agonists and theophylline to the patient results to generate a better spirometric change than administering a single prescription alone (Anne, 2014). Tiotropium recovers the patient’s health condition and decreases patients hospitalisations and exacerbations as opposed with regular ipratropium and placebo. Beta 2-agonists are a sort of bronchodilator medications. This means that they enlarge (dilate) and relax the patients air-passage in the lungs, making breathing relaxed. Research proves that inhaled beta2-agonists are active in treating signs of COPD and enhancing the lung utility as...
