Brief summary
The brain pulse monitor is a new non-invasive method that uses light to monitor brain oxygen levels and blood flow. The purpose of the study is to determine if the brain pulse monitor accurately detects falls in brain oxygen and blood flow associated with stroke. The study will enrol adult patients with or at risk of developing a stroke. The target group are patients presenting to hospital with stroke, patients with sub-arachnoid haemorrhage that develop vasospasm and patients undergoing surgeries associated with a risk of stroke, such as carotid and cardiac surgery. The major outcome is to assess the accuracy of the brain pulse monitor to detect reduced brain oxygen and blood flow changes associated with stroke.
Interventions
The Brain Pulse Oximeter is a non-invasive monitor that uses light to detect brain oxygen levels and brain photoplethysmography (PPG) signals. This is a monitoring study that will assess a novel point of care monitor that detects stroke. The accuracy of this device to detect stroke will be compared with the current gold standard. Patients presenting with stroke will have the monitor placed on the head and monitored prior to and following acute treatment of stroke, whilst they remain in hospital for a maximum of 14 days. The monitoring will be undertaken by the research group which includes the stroke neurological service. The monitor's outputs will not be used to guide treatment.
