Ambulatory monitoring
Ambulatory monitoring is the recording of physiological signals, chiefly blood pressure, ECG, and activity, during patients' daily lives, using ABPM, Holter and patch recorders, and implantable loop devices.
Anorectal manometry
Anorectal manometry is a gastroenterology test measuring pressures and reflexes in the anal canal and rectum with a catheter to diagnose defecatory disorders and fecal incontinence.
Behavior Rating Inventory of Executive Function
The Behavior Rating Inventory of Executive Function (BRIEF) is a family of parent, teacher, and self-report questionnaires rating everyday executive function behaviors, first published in 2000 by Gerard Gioia and colleagues.
Cardio Ankle Vascular Index
Cardio-ankle vascular index (CAVI): a blood pressure-independent index of arterial stiffness from the aortic origin to the ankle, measured with the VaSera device; normal below 8.0, developed in 2004 from stiffness parameter beta and Bramwell-Hill equation.
Carotid-Femoral Pulse Wave Velocity
Carotid-femoral pulse wave velocity (cfPWV) is the gold-standard noninvasive measure of aortic stiffness, calculated as wave travel distance divided by carotid-to-femoral transit time, with a 10 m/s cut-off and standardized distance methods.
Displacement plethysmography
Displacement plethysmography is a family of diagnostic techniques measuring volume change of a limb or whole body by detecting displaced fluid or air, including air-displacement plethysmography.
Eating Disorder Examination questionnaire
The Eating Disorder Examination questionnaire (EDE-Q) is a 28-item self-report measure of eating disorder psychopathology, adapted from the EDE interview and introduced by Fairburn and Beglin in 1994.
EEG monitoring
EEG monitoring is the continuous or prolonged recording of the brain's electrical activity through scalp electrodes, used to detect seizures, including nonconvulsive ones, in intensive care.
Electromagnetic articulography
Electromagnetic articulography (EMA) is a biomedical technique that tracks tongue, lip, and jaw movements during speech with sensor coils, supporting phonetic research and clinical assessment.
EQ-5D
The EQ-5D is a standardized, self-administered questionnaire measuring health-related quality of life across five dimensions, developed by the EuroQol Group and widely used for computing QALYs in health technology assessment.
Fetal electrocardiography
Fetal electrocardiography (fECG) records the fetal heart's electrical activity to assess cardiac rhythm and wellbeing, using noninvasive maternal abdominal electrodes or a fetal scalp electrode applied during labor.
Fetal Heart Rate
Fetal heart rate (FHR), also called fetal heart monitoring via cardiotocography or electronic fetal monitoring, is the fetus's heartbeat rate, normally 110–160 bpm, used to assess fetal well-being during labor.
Fetal pulse oximetry
Fetal pulse oximetry is a labor-monitoring technique that measures fetal arterial oxygen saturation through a sensor placed after the membranes rupture, as an adjunct to fetal heart rate monitoring.
Heart Function Tests
Heart function tests measure cardiac electrical activity, pumping strength, valves, and blood flow: ECG, BNP blood tests, echocardiography, cardiac CT and MRI, stress testing, and angiography, with guideline-based selection by patient risk.
Kinetocardiography
Kinetocardiography (KCG), also indexed as vibrocardiography and apex cardiography, is the graphic recording of low-frequency (0-30 Hz) chest wall movements caused by cardiac impulses, introduced by Eddleman in 1953.
Laser Doppler flowmetry
Laser Doppler flowmetry is a non-invasive optical technique that measures blood flow in tissue from the Doppler shift of laser light scattered by moving red blood cells.
Lung clearance index
The lung clearance index (LCI) is a pulmonary function test that counts how many breaths it takes to wash an inert tracer gas out of the lungs.
Manometry
Manometry is a diagnostic technique that measures pressure inside the esophagus to assess muscle function and diagnose motility disorders, with high-resolution manometry using closely spaced sensors as the gold standard.
Multiple breath washout
Multiple breath washout (MBW) is a pulmonary function test that washes a tracer gas from the lungs during tidal breathing; its lung clearance index detects early obstructive lung disease even when spirometry is normal.
Multiple sleep latency test
The multiple sleep latency test (MSLT) is a clinical neurophysiological procedure measuring daytime sleepiness through five scheduled naps, the standard diagnostic tool for narcolepsy and idiopathic hypersomnia.
Perimetry
Perimetry is the systematic measurement of the visual field, presenting light stimuli at many locations to detect and monitor glaucoma and localize retinal and neuro-ophthalmic disease.
Phonocardiography
Phonocardiography (PCG) is a biomedical technique that records the heart's acoustic vibrations as a waveform, first performed by Einthoven and Geluc in 1894 and later flown on Gemini missions.
Phototesting
Phototesting is a dermatology diagnostic procedure applying measured doses of ultraviolet or visible light to the skin to reproduce and quantify abnormal photosensitivity, usually by measuring the minimal erythema dose.
Pressure-flow study
A pressure-flow study is an invasive urodynamic test that records bladder pressure and urine flow simultaneously during voiding, the reference standard for diagnosing bladder outlet obstruction in men.
Pulmonary Wedge Pressure
Pulmonary artery wedge pressure (PAWP, PCWP): left-sided filling pressure measured via balloon-occlusion with a Swan-Ganz catheter; thresholds 15 mmHg (rest) and 25 mmHg (exercise); imperfect surrogate for LVEDP.
Rechallenge (pharmacology)
Rechallenge is the readministration of a drug suspected of causing an adverse reaction, after the drug was stopped, to determine whether the reaction recurs; it is rarely ethically justified.
Transcutaneous Blood Gas Monitoring
Transcutaneous blood gas monitoring (tcPO2/tcPCO2, transcutaneous capnometry): noninvasive, continuous measurement of skin-surface oxygen and carbon dioxide partial pressures using heated electrodes, developed from 1972, routine in neonatal ICU.
Videourodynamics
Videourodynamics (VUDS) is a diagnostic urodynamic study combining cystometry and pressure-flow measurements with real-time fluoroscopic imaging, most valuable in neurogenic bladder dysfunction and complex lower urinary tract conditions.
Wave intensity analysis
Wave intensity analysis is a time-domain hemodynamic method, introduced by Parker and Jones in 1990, that quantifies forward and backward arterial waves from simultaneous pressure and velocity measurements.
