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, which is a global measure of esophageal acid exposure. A Demeester ...
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 ( GERD) or gastro-oesophageal reflux disease ( GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. [ 6][ 7][ 10] Symptoms include dental corrosion, dysphagia, heartburn, odynophagia ...
Chronic bronchitis, an inflammation in the major airways such as the bronchial tubules, causes the coughing of coloured sputum. Most carriers of chronic bronchitis have a history of smoking. Chronic bronchitis is on a spectrum of smoking-related lung disease also known as chronic obstructive pulmonary disease (COPD).
Heartburn, also known as pyrosis, cardialgia or acid indigestion, [2] is a burning sensation in the central chest or upper central abdomen. [3] [4] [5] Heartburn is usually due to regurgitation of gastric acid (gastric reflux) into the esophagus. It is the major symptom of gastroesophageal reflux disease (GERD). [6]
A urine test strip or dipstick is a basic diagnostic tool used to determine pathological changes in a patient's urine in standard urinalysis. [1] A standard urine test strip may comprise up to 10 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.
Penile plethysmography (PPG) or phallometry is a measurement of blood flow to the penis, typically used as a proxy for measurement of sexual arousal.The most commonly reported methods of conducting penile plethysmography involves the measurement of the circumference of the penis with a mercury-in-rubber or electromechanical strain gauge, or the volume of the penis with an airtight cylinder and ...
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, and so the pH meter is sometimes ...
