The aim of this study was to establish a standardized protocol for sleep endoscopy to differentiate obstruction patterns in obstructive sleep apnea (OSA). Target-controlled infusion (TCI) of the sedative was combined with real-time monitoring of the depth of sedation using bispectral analysis.

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results. The number in the measurement can be represented in different ways, including decimal form and scientific notation, which is...

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units. Units of measurement derived from the mathematical combination of SI base units are called SI-derived units. For example, the ratio of the SI unit for distance (meter; m) and the SI unit for time (second; s) gives the SI-derived unit...

Mechanical engineering is one of the oldest branches of engineering. It deals with designing, analyzing, and manufacturing machines and mechanical systems. To ensure precise and accurate calculations, units of measurement are used. They provide a standard system for expressing and comparing physical quantities. There are various well-known historical measurement systems, such as the Babylonian system, the Roman system, the Egyptian system, the Olympian system, the British system, and the Indus...

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds. Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...
FAQs
The light source and camera provide a direct view of internal surfaces, helping healthcare professionals identify areas that appear abnormal before guiding instruments to those locations. This approach links the tissue sample to a visually characterized site rather than collecting material without visual guidance. In cancer research, that connection supports more precise diagnosis and interpretation of tumor-related findings.
A collected specimen becomes especially valuable when researchers know its clinical and visual context. Endoscopy units can provide well-characterized tumor samples associated with the examined abnormal area, allowing investigators to connect tissue findings with diagnosis, staging, or biomarker analysis. This contextual information strengthens the usefulness of samples for studying cancer biology and evaluating research questions.
Biopsy obtains tissue from a selected area for examination, while polyp removal can provide a larger or more complete specimen from a visible lesion. Both procedures use the endoscope to target abnormal findings, but the resulting materials may support different analyses. In cancer research, these samples contribute to diagnosis, biomarker assessment, and the study of precancerous or cancer-related changes.
A cancer-focused examination may begin with visual inspection of internal organs, followed by identification of abnormal areas and targeted intervention. Depending on the finding, professionals can collect tissue or remove a polyp while observing the procedure through the endoscope. The resulting clinical observations and specimens can then support diagnostic assessment, staging, and subsequent research analysis.
These units contribute at several stages, including screening, diagnosis, staging, and biomarker analysis. Their procedures can generate both visual information and tissue specimens, allowing clinical findings to be considered alongside laboratory evaluation. This combination helps research teams investigate cancers more systematically, particularly when they need samples linked to a documented examination and patient outcome information.
A controlled endoscopy unit provides a structured setting for assessing new imaging methods, endoscopic therapies, and patient outcomes. Investigators can compare what the procedure reveals, what targeted interventions achieve, and how patients fare afterward. This makes the unit relevant not only to routine clinical care but also to research that examines whether emerging approaches improve cancer detection or treatment.
