The study by Berlowitz et al. (2009) clearly illustrates its aims from the onset, and provides a brief but concise background on the subject matter. They aim to uncover the feasibility of CPAP in the management of OSA patient who are tetraplegic. The article is a quantitative study, and utilizes statistical evidence in a clear manner. The study utilizes a cohort of patients in a spinal center. The research design is appropriate with regards to the objectives and setup of the study. The study conclusion is well justified. The findings of the study are applicable in the present paper, in that they prove the efficacy and feasibility of CPAP in OSA patients, with a focus on patients with other co-morbidities.
Alonso-Fernandez, Garcia-Rio, Arias et al (2008) conduct a study, which aims to add new knowledge, with regards to CPAP and the prevention of complications in patients with Obstructive Sleep Apnea. The study tests a hypothesis- CPAP therapy attenuates nitrate deficiency and oxidative stress. Both these two processes are imperative in the development of complications in patients with obstructive sleep apnea. The study utilizes a randomized controlled double blind research design. This design is appropriate in uncovering the efficacy of CPAP. Selection bias is minimized in the study, where 31 newly diagnosed OSA patients are randomized and compared to 15 randomly selected healthy individuals. Correct statistical analyses are conducted, thus enhancing believability of results. The findings of this study are imperative to the present study in that they prove the efficacy of CPAP in decreasing complications in newly diagnosed OSA patients. Therefore, the imperativeness of CPAP in early disease can be derived from the authors` conclusion.
Sweeting (2012) elaborates on the use of CPAP for people with OSA. The article is not a primary study; hence, a disadvantage. Nonetheless, the au...
