Obligatory medical device diagnostics.
- Electrocardiogram (ECG; recording of the electrical activity of the heart muscle).
- X-ray of the thorax (X-ray thorax/chest), in two planes.
Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Computed tomography/magnetic resonance imaging of the skull (cranial CT or cCT/cranial MRI or cMRI) – for suspected neurologic events and in all patients with coma of unclear genesis/origin.
- Angio-computed tomography (CT angiography (CTA); radiologic examination procedure in which blood vessels are examined with the aid of computed tomography (CT)) of the supraaortic vessels – in coma and in the absence of focal neurology (localized (focal) disease)
- Encephalogram (EEG; recording of the electrical activity of the brain) – provides information about the electrical activity of the brain; in the case of a first-ever epileptic seizure.
- Abdominal ultrasonography (ultrasound examination of the abdominal organs) – if a cause in the liver or kidneys is suspected.
