When a patient suddenly loses consciousness, it is often referred to as syncope. Syncope is characterized by a transient loss of consciousness typically caused by a decrease in blood flow to the brain. This can happen as a result of various factors such as dehydration, standing up too quickly, or a medical condition that affects the heart or blood vessels.

In medical practice, recognizing syncope is crucial because it can sometimes indicate underlying health issues that may require further investigation. It is distinct from other conditions like a stroke, which involves an interruption of blood flow to the brain and presents with different clinical signs, or cardiac arrest, where the heart stops functioning and leads to the loss of consciousness due to a lack of blood circulation. A seizure also involves a loss of consciousness but is usually associated with abnormal electrical activity in the brain and might present with distinct physical symptoms such as convulsions.

Understanding syncope and its implications allows EMTs and other healthcare providers to gather appropriate information about the patient’s condition, determine the necessary interventions, and provide effective care on the scene or during transport.
