This assignment is a critique of a quantitative research study by Ayhan H. et al (2009) in which they compared two different methods in oxygen delivery in the early postoperative period. It was conducted in Turkey by well qualified people and it was published in the Journal of Advanced Nursing which is a journal with credibility.   The purpose of a critique is to try and determine the strength and weaknesses of a write up therefore it should highlight the significance and validity of what is being studied.(Lo Biondo – Wood and Harber   2006 ) This critique will consider the relevance of the research article in relation to practice. Ethical issues, data collection, data analysis and the sample used will be taken into consideration.   In conclusion the study will be compared with other related evidence.
Although there are several frameworks for doing a critique, the framework that will be used is that of Parahoo (2006) which requires the writer to evaluate the title, abstract, literature review, methodology, results, discussion and recommendations. The purpose of a framework according to Parahoo (2006) is to help in covering all aspects of the research as all sections should be critically analysed in order to establish credibility and conformity.
This study was seeking to compare the effectiveness of nasal cannulae to that of face masks.   It also looked at patient satisfaction levels in relation to the two delivery methods. No hypothesis was clearly given, leaving the reader to deduce from the background material. Burns and Grove (2005), state that researchers should quote a hypothesis early on in the study. However, they also say that in cases where the outcome cannot be predicted it is inappropriate to give one. It can therefore be said that the hypothesis was that ‘oxygenation status is affected by oxygen delivery method’. This was supported by statistics which show that twenty four people from the ‘face mask’ group removed their masks during the experiment as...
