1. These stenoses can be more adequately identified and assessed with catheter cerebral venography and manometry . 2. The oxygen uptake is detected by manometry . 3. Esophageal manometry is not recommended for use in diagnosis, being recommended only prior to surgery. 4. Manometry is performed next to confirm.5. HRM systems also require advanced computer hardware and software to store and analyze the manometry data. 6. However, esophageal manometry is uncomfortable for patients and impractical to use in most sleep centers. 7. A test called esophageal manometry can examine the muscular action of the esophagus, including sphincter function. 8. Other techniques include manometry , balloon expulsion test, evacuation proctography ( see defecating proctogram ), and MRI defecography. 9. A normal endoscopy should be followed by manometry , and if manometry is also normal, the diagnosis is functional dysphagia. 10. A normal endoscopy should be followed by manometry, and if manometry is also normal, the diagnosis is functional dysphagia.
