Study design	Randomised controlled cross-over trial
Secondary study design	Randomised cross over trial
Study type	Participant information sheet
Scientific title	The effects of improving oxygen concentration in the reduction of dialysis induced myocardial stunning - a pilot study
Study objectives	Increasing oxygen concentration by administering inhaled oxygen reduces the severity and frequency of haemodialysis induced myocardial stunning.
Ethics approval(s)	Trent Research Ethics Committee, 06/07/2009, ref: 09/H0405/18
Health condition(s) or problem(s) studied	Dialysis-induced myocardial stunning
Intervention	4 litres oxygen delivered by nasal cannulae during standard 4-hour haemodialysis.
Intervention type	Other
Primary outcome measure(s)	1. Myocardial stunning 2. Development of regional wall motion abnormalities Key observations are taken pre-dialysis (baseline) and 15 minutes prior to end of dialysis (peak stress) by cardiac echocardiography (for later offline semi-automated analysis for regional wall motion abnormalities).
Key secondary outcome measure(s)	Intradialytic haemodynamics; haemodynamic variables observed pre-dialysis, and throughout dialysis treatment, with continuous non-invasive measurement by finometer, and NICOM (bioreactance).
Completion date	01/11/2010
Reason abandoned (if study stopped)	Lack of staff/facilities/resources
