Term Description

Difference (gap) between gastric mucosal (PgCO2) and end-tidal (EtCO2) partial pressures of carbon dioxide. PgCO2 is measured by gastric tonometry.

Part Description

LP76227-5   Tonometry
Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine the IOP. IOP is an important aspect in the evaluation of patients at risk for glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg). Source: Regenstrief LOINC
