Monitor Ventilation

Contribution of gular pumping to lung ventilation in monitor lizards.

A controversial hypothesis has proposed that lizards are subject to a speed-dependent axial constraint that prevents effective lung ventilation during moderate- and high-speed locomotion. This hypothesis has been challenged by results demonstrating that monitor lizards (genus Varanus) experience no axial constraint. Evidence presented here shows that, during locomotion, varanids use a positive ...

Is it time to monitor flow bias during mechanical ventilation?

The topic of data warehousing encompasses architec-tures, algorithms, and tools for bringing together selected data from multiple databases or other information sources into a single repository, called a data warehouse , suitable for direct querying or analysis. In recent years data warehousing has become a prominent buz-zword in the database industry, but attention from the database research c...

Does pulse oximetry accurately monitor a patient's ventilation during sedated endoscopy under oxygen supplementation?

INTRODUCTION Pulse oximetry (SpO2) measures oxygen saturation but not alveolar ventilation. Its failure to detect alveolar hypoventilation during sedated endoscopy under oxygen supplementation has been reported. The aim of this study was to measure the masking effect of oxygen supplementation in SpO2 when alveolar hypoventilation develops during sedated endoscopy. METHODS A total of 70 patien...

A Low-cost Technique to Monitor Ventilation Fan Operation at Animal Buildings

When measuring emissions of gases, particulate, and odor from animal buildings, the ventilation data are equally important as the concentration data, because emission rate of a pollutant is the product of its concentration and the ventilation rate. However, effectively measuring and monitoring building ventilation remains a technical challenge, especially in barns with numerous fans. Although s...
