Advanced Medical carries sophisticated spirometers from highly regarded manufacturers including CardioTech and Puritan.  Providing precise and accurate measurement of real time flow-volume loop, these specialized apparati measure ventilation, or the volume of air inspired and expired by the lungs.  Useful in identifying obstructive and restrictive ventilation patterns, spirometers are the primary tool of Pulmonary Function Tests (PFTs).  These devices aid in determining the cause of shortness of breath, evaluating contaminants’ effects on lung function, diagnosing acute and chronic lung diseases, screening lung function before surgery, and assessing the effects of medication.  These models are noted for their intuitive design, quick set-up, wide variety of applicable clinical settings, and extensive testing parameters.  Disposable flow sensors, which minimize cross-contamination and reduce clean up time, are available.
