Whole Body Plethysmograph – vivoFlow launches at EB 2019
Whole Body Plethysmograph – vivoFlow Launches at EB 2019 SCIREQ is preparing for the upcoming Experimental Biology Meeting that will take place in Orlando from April 6-9, 2019. At this meeting we launch our latest development: the vivoFlow – WBP (Whole Body Plethysmograph Chamber). The vivoFlow is fully compatible with our current system and has several design features which both […]
Obese Mice Study Proves to Use the Ideal Weight
Obese Mice Study Proves to Use the Ideal Weight When working with obese mice, what weight to use when performing flexiVent measurements? This question is quite an important one for two reasons. First, there is a substantial difference in weight between the obese subjects vs. the lean control group. For instance, obese mice can weigh […]
QuickPrime Measurements for Deeper Insight
QuickPrime Measurements for Deeper Insight What is the forced oscillation technique (FOT)? Simply put, the forced oscillation technique is: Pausing ventilation Sending a test signal to the lungs Measuring the subject’s response The test signal is either a single frequency (matching the breathing frequency of the subject) or made up of multiple frequencies. When adding […]
New Insights From Pressure-volume Loops
New Insights From Pressure-volume Loops Lung function measurements with the flexiVent frequently include Pressure-Volume (PV) loops for insight on the intrinsic elastic properties of the respiratory system. The typical maneuver slowly inflates the lungs in steps, from Positive-End Expiratory Pressure (PEEP; 3 cmH2O) to 30 cmH2O, and then deflate them in a similar way to generate a […]
Electronic Nicotine Delivery Systems (ENDS)
Electronic Nicotine Delivery Systems (ENDS) Electronic nicotine delivery systems (ENDS) are gaining in popularity in recent years. As a broad overview, an ENDS unit is a battery-powered device which heats up a metal resistive coil to produce an inhalable vapour of an e-liquid, without tobacco combustion. This e-liquid typically consists of Propylene Glycol (PG) and […]
First Idiopathic Pulmonary Fibrosis Mouse Model
First Idiopathic Pulmonary Fibrosis Mouse Model Congratulations to Dr. Beers and his team for developing and phenotyping the first idiopathic pulmonary fibrosis mouse model! Pulmonary fibrosis mouse model – why do we need them? Mouse models are an important research tool for preclinical scientists. Alternatives including cells and computer simulations do exist, however they are not […]
