Aims and Objectives

To explore the perceptions and experiences of aged patients with acute respiratory failure who are receiving NIV treatment in order to understand the reasons behind voluntary withdrawal from a prescribed regime.


Non-invasive ventilation (NIV) has been shown to be effective in acute respiratory failure of various aetiologies in different health care systems and ward settings (Elliot 2005). In a study carried out by (Rupani et al 2009) results showed that (NIV) reduce mortality and intubation rates in patients with chronic obstructive pulmonary disease (COPD) and acute type 2 respiratory failure.

However, compliance with this form of treatment is frequently poor, which may lead to admission in Intensive Care Unit for tracheal intubation or death. I have worked on respiratory ward as clinician looking after patients receiving NIV treatment and what I discovered is that 1 in 5 patients admitted per week decline or voluntarily withdrew from treatment.   Given this background, I then got interested in investigating the patients$acirc; perception and experiences of being on NIV treatment.


A phenomenological approach formed by the ideas of Heidegger will be used.


The study aims to recruiting a maximum of ten patients to take part in semi-structured interviews following ethical approval. Patients are going to be recruited from Cardiff and Vale University Hospitals departments of respiratory medicine.

Relevance to clinical practice

The benefits of this research are that it will improve our understanding of the challenges faced by aged patients receiving NIV treatment. This will then provide clinical members with evidence for the development of new procedures; strategies or implementation$acirc; s aimed at reducing non compliance through the provision of best quality of NIV treatment possible.
