Andmesignaale

Andmesignaale is a term that appears only occasionally in English-language sources and does not have a widely established definition in mainstream physiology or signal processing. In contexts where it is encountered, it is often used as a generic label for signals related to breathing, such as acoustic breath sounds or other physiological signals that accompany respiration. The exact meaning can vary by author, and the term itself is not standard in major medical or engineering references.

Etymology and variants. The form andmesignaale is not a standard term in Dutch, Scandinavian, or other Germanic languages. It may be a typographical variant or a regional coinage of related terms such as ademsignaal (Dutch for breathing signal) or andningssignal (Scandinavian equivalents meaning respiration signal). Because of its ambiguity, it is typically treated as a historical or informal label rather than a canonical term.

Domains and usage. In physiology and clinical monitoring, signals related to breathing are commonly studied under more established terms such as respiratory rate, tidal volume, flow, capnography, and acoustic respiration signals. In signal processing and sleep research, breathing-related signals are analyzed to assess sleep apnea, respiratory patterns, and autonomic regulation. Andmesignaale, when used, usually signals a category rather than a specific metric.

Measurement methods. Typical approaches include nasal/oral flow sensors, thoracic or abdominal effort belts, microphones for acoustic signals, spirometry for volume, and capnography for CO2 concentration. Interpretation focuses on rate, regularity, depth, and the coupling between respiration and other physiological signals.
