NHS & Clinical Guidance
Not medical advice. These are general reference ranges for healthy adults, based on NHS guidance. They do not apply to children, pregnant women, or people with pre-existing conditions — your personal normal range may differ significantly. If a reading concerns you, contact your GP or call NHS 111. In an emergency — chest pain, collapse, or severe breathlessness — call 999 immediately.
