Summary
The non-nutritive suck (NNS) device accurately measures infant sucking behavior. This quantitative NNS assessment serves as a biomarker for predicting future development and identifying at-risk infants for early intervention.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Biomedical Engineering
Background:
- Non-nutritive suck (NNS) behavior in infants is a critical indicator of development.
- Quantifying NNS provides valuable insights into infant health and potential developmental trajectories.
- Existing methods for NNS assessment lack precision and user-friendliness.
Purpose of the Study:
- To introduce and validate a novel, transportable pressure transducer system for quantifying infant NNS behavior.
- To establish NNS parameters (duration, amplitude, frequency) as reliable biomarkers for developmental outcomes.
- To explore the utility of NNS assessment in diverse research areas, including feeding interventions, population studies, and environmental health.
Main Methods:
- Development of a user-friendly, transportable pressure transducer system to record NNS on a pacifier.
- Analysis of NNS signals to derive quantitative measures of burst duration (s), amplitude (cmH2O), and frequency (Hz).
- Application of the NNS device in various research contexts, including intervention studies, developmental characterization, and neurodevelopmental correlation.
Main Results:
- The NNS device successfully quantifies key NNS parameters with accuracy and reliability.
- NNS features have been correlated with feeding interventions, population-specific development, and neurodevelopmental outcomes.
- The device has been utilized to investigate the impact of in utero exposures on infant NNS development.
Conclusions:
- Quantitative NNS assessment using the developed device serves as a valuable biomarker for predicting feeding, speech-language, cognitive, and motor development.
- The NNS device facilitates the identification of infants at risk for developmental delays.
- Early intervention can be rapidly implemented based on NNS parameter correlations with neurodevelopmental outcomes.

01:16Measurement of Fluid Pressure
195
Fluid pressure is commonly measured using devices called manometers, which rely on liquid columns to indicate pressure differences. The height of a liquid column in a manometer reflects the pressure exerted by the fluid, providing a simple yet effective means of measurement. Different types of manometers serve specific purposes based on their configurations and the type of fluids involved.
A basic form of manometer is the piezometer, a vertical tube open at the top and filled with the same...

01:28Pipe Flowrate Measurement
685
In pipe flow measurement, orifice, nozzle, and Venturi meters are commonly used to determine fluid flowrates by constricting the flow area, which increases fluid velocity and reduces pressure. This pressure difference, governed by Bernoulli's principle and adjusted for real-world conditions, is essential for calculating flowrate. Each meter type is suited to specific applications based on accuracy, efficiency, and compatibility with various flow conditions.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
