Brief summary
Heart failure (HF) is one of the most common causes of hospitalisation, particularly among the elderly. Breathlessness is a common reason for patients presenting to hospital. Although the use of oxygen in acute HF with hypoxaemia is well established, there is no evidence to support or refute the use of oxygen in chronic HF. The OXYGEN-HF Study seeks to test the hypothesis that oxygen administered in conjunction with a dyspnoea action plan will decrease rates of hospitalisation compared with air and a dyspnoea action plan and a dyspnoea action plan alone in patients with New York Heart Association Class III-IV heart failure.
Interventions
Heart Failure Dyspnoea Action Plan including strategies for symptom management and when to contact health professionals will be provided to participants at baseline and reinforced at 6 weeks, 3 months, 6 months. Participants will be instructed to use oxygen administered via nasal cannulae at 2-3 Litres per minute (approximately 28% oxygen) overnight while sleeping (approximated at 6-8 hours) and when short of breath over a period of 6 months. Symptom management instructions will be given in written and verbal form at baseline and each of the outcome assessment points at 6 weeks, 3 months and 6 months.
