A body suspended in a vertical position will suffer from blood pooling in the legs, draining the blood and therefor the oxygen from the brain. The symptoms of suspension syncope will start affecting the brain within 4 to 20 minutes.
All those ‘working at height’ must be trained in how to recognise, manage and prevent suspension syncope.
The rescue needs to be carried out as soon as possible to prevent the onset of the condition. A perfect rescue will be done as quickly as possible but as slow as is necessary to ensure the safety of both casualty and rescuer.
The current HSE guidance on treatment of the condition is that the casualty should be placed in the recovery position and normal principles of first aid applied.
Once rescue of a suspended casualty has been successful relevant first aid treatment should be provided.
