Introduction

This paper will review the article Qualitative analysis of patients' intensive care experience during mechanical ventilation. This article was authored by Kefang Wang, Bing Zhang, Chunyan Li and Chen Wang appeared in the Journal of Journal of Clinical Nursing in 2008. As the title implies, this article deals with the medical ventilation in intensive care.

Methodology Used in the Article

The methodology used in this article is in-depth interviews of the patients. The in-depth interview is a qualitative method of analysis, which proceeds as a confidential and secure conversation between an interviewer and a respondent. By means of a thorough composed interview guide, which is approved by the client, the interviewer ensures that the conversation encompasses the topics that are crucial to ask for the sake of the purpose and the issue of the survey.

The method of the in-depth interview is appropriate if you need to gain an insight into individual evaluations of specific material. This method is the right one to choose if the primary objective with the survey, for example is to evaluate a new packaging, an advertisement or a storyboard. Namely the method can produce very precise and specific answers as well as an exhaustive and varied knowledge about individual determined experiences, opinions and motives, which the group interview and the quantitative methods cannot encompass.

The method of the in-depth interview is also appropriate if your subject and issue are in the nature of something controversial, sensitive or tabooed. One of the advantages of the in-depth interview is that there is time for the respondent, in peace, to further develop and give reasons for his or hers individual point of views - without being influenced by the opinions of other respondents.

Apart from that the method typical involves different techniques which encompass spontaneous, emotional and perhaps unconscious circumstances within the respondent.

An in-depth interview most often takes place in a private home, where the respondent is in his or hers natural surroundings. In this way, the respondent is relaxed and therefore open and willing to reply to the exhaustive questions. An in-depth interview typically varies between 1½ and 2 hours and is recorded on tape or video for the sake of the following analysis and the writing of the report. For the sake of the respondents, these recordings are deleted half a year after at the latest.

The design of the modern positive-pressure ventilators were mainly based on technical developments by the military during World War II to supply oxygen to fighter pilots in high altitude. Such ventilators replaced the iron lungs as safe endotracheal tubes with high volume/low pressure cuffs were developed. The popularity of positive-pressure ventilators rose during the polio epidemic in the 1950s in Scandinavia and the United States and was the beginning of modern ventilation therapy. Positive pressure through manual supply of 50% oxygen through a tracheostomy tube led to a reduced mortality rate among patients with polio and respiratory paralysis. However, because of the sheer amount of man-power required for such manual ...
