Fatigue management refers to a structured set of strategies and techniques designed to help people with persistent tiredness understand, monitor, and reduce the impact of fatigue on their daily life. It is an important part of recovery for many cardiac arrest survivors, for whom fatigue is one of the most commonly reported and most disabling long-term symptoms.
Why fatigue after cardiac arrest is different
Post-cardiac arrest fatigue is not the same as ordinary tiredness. It is often described as a profound exhaustion that does not improve with rest, worsens with physical or mental effort, and can cause significant cognitive slowing. It may arise from a combination of factors: brain injury, the physical effort of recovery, disrupted sleep, medication side effects, emotional distress, and deconditioning.
Core principles
Fatigue management programmes are typically delivered by occupational therapists and draw on several interconnected principles:
- Activity pacing: spreading activities throughout the day and week, interspersing rest with effort rather than pushing through until exhaustion and then crashing
- Energy envelopes: understanding personal energy limits and planning activities within those limits rather than exceeding them and paying a high cost the following day or days
- Rest scheduling: building planned, deliberate rest periods into the day before fatigue becomes severe
- Prioritisation: deciding which tasks are essential, which can be delegated, and which can be dropped
- Sleep hygiene: improving the quality of night-time sleep to support daytime energy levels
Getting help
Occupational therapists, fatigue clinics, and long-term conditions services can provide structured fatigue management support. Some cardiac rehabilitation programmes include fatigue management components. GPs can refer survivors to appropriate services.
