A reflux episode is defined as esophageal pH drops below four. Esophageal pH monitoring is performed for 24 or 48 hours and at the end of recording, a patient's tracing is analyzed and the results are expressed using six standard components. Of these 6 parameters, a pH score called Composite pH Score or DeMeester Score has been calculated ...
Impedance–pH monitoring. Impedance–pH monitoring is a technique used in the diagnosis of gastroesophageal reflux disease (GERD), by monitoring both impedance and pH. [1] [2] Patients with ongoing symptoms while on proton-pump inhibitor (PPI) therapy are commonly diagnosed with impedance–pH monitoring while continuing their medications.
Gastroesophageal reflux disease treatments can include intense monitoring with a dual channel 24-hour pH probe for diagnosis of the severity of GERD. Other monitors such as nasopharyngoscopy can reveal glottis changes associated with the refluxes that occur.
Polysomnography (PSG) is a multi-parameter type of sleep study and a diagnostic tool in sleep medicine.The test result is called a polysomnogram, also abbreviated PSG.The name is derived from Greek and Latin roots: the Greek πολύς (polus for "many, much", indicating many channels), the Latin somnus ("sleep"), and the Greek γράφειν (graphein, "to write").

Beckman model 72 pH meter, 1960. 781 pH/Ion Meter pH meter by Metrohm. A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH. [2] The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode ...
A transesophageal echocardiogram, or TEE ( TOE in the United Kingdom and other countries such as Australia and New Zealand, reflecting the British English spelling transoesophageal ), is an alternative way to perform an echocardiogram. A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus. [1]
A mobility shift assay is electrophoretic separation of a protein–DNA or protein–RNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel). [4] The speed at which different molecules (and combinations thereof) move through the gel is determined by their size and charge, and to a lesser extent ...
