Intended Use

The Micro I spirometer is intended to measure the maximal volume and flow of air that can be moved out of a patient's lungs. The system is intended for use with pediatric and adult patients over the age of 3 years in hospitals, physician offices, laboratories and occupational health testing environments.

Device Story

Micro I is a handheld, portable, microprocessor-based spirometer for measuring expiratory lung flows and volumes. Input: patient exhales into a disposable mouthpiece connected to a uni-directional digital volume transducer. Operation: transducer consists of an acrylic tube with a low-inertia vane on jeweled bearings; airflow creates a vortex causing vane rotation; rotation detected by infrared beam interruption producing electrical pulses. Software: onboard processor converts pulses to volume and flow rate; calculates indices including FEV1, FVC, FEV6, PEF, and FEF metrics. Usage: hospitals, clinics, laboratories, occupational health settings; operated by clinicians or trained personnel. Output: graphic monochrome LCD displays results. Benefit: provides objective pulmonary function data to assist in diagnosing and monitoring respiratory conditions.

Clinical Evidence

No clinical data provided. Substantial equivalence is supported by bench testing, including biocompatibility testing per ISO 10993-1, safety and EMC testing per IEC 60601-1 and IEC 60601-2, and performance verification against ATS/ERS standardization of lung function testing.

Technological Characteristics

Handheld spirometer; uni-directional digital volume transducer (acrylic tube, polyester vane, stainless steel pivot). Housing: PC/ABS Cycoloy C2800 with soft coating. Power: 2x AA NiMH rechargeable batteries. Display: 128x128 pixel backlit monochrome LCD. Connectivity: USB. Software: microprocessor-based, rule-based calculation of expiratory indices. Sterilization: turbine is cleanable/sterilizable.

Indications for Use

Indicated for pediatric and adult patients over 3 years of age requiring pulmonary function testing to measure lung volume and flow parameters.

Micro Diary K100928 Code BZG - 5.10 Predicate Device Company CareFusion ### 5.11 Device Description Description & function: The Micro I spirometer is a hand held portable microprocessor based device designed to measure expiratory flows and volumes. To perform a spirometry test the user first inserts a mouthpiece into the mouthpiece holder of the spirometer, which aligns it with the volume transducer. The unit is then turned on and displays instructions and prompts according to the device type. When prompted to do so by the operator, the patient inhales as deeply as possible, seals his/her lips around the mouthpiece and exhales as hard and as fast as possible until no more air can be exhaled. The device converts the airflow to an electrical signal, and the onboard software calculates the required values. ## Scientific Concept: The scientific concept which forms the basis of this device is the Carefusion uni-directional digital volume transducer. The transducer consists of an acrylic tube with a freely rotating vane supported on iewelled bearings positioned between a fixed swirl plate and a cross bar. As air is passed through the transducer, a vortex is created by the {2}------------------------------------------------ swirl plate, which causes the low inertia vane to rotate. The rotation of the vane is detected by the interruption of an infra red beam which produces an electrical pulse train at the output of a phototransistor. The number of rotations is proportional to the volume of air passed through the turbine, and the rate of rotation is proportional to the flow rate. Using the integrated software the Micro I calculates a range of expiratory indices. ### Significant physical & performance characteristics: Performance (measurements) Forced Expired Volume in 1 second (FEV1) Forced Expired Volume in 6 second (FEV6) Forced Vital Capacity (FVC) Forced Expiratory Ratio (FEV1/FEV6) Forced Expiratory Ratio (FEV1/FVC) Peak Expiratory Flow Rate (PEF) Mid Expiratory Flow (FEF25-75) Expiratory Flow at 75% of volume remaining (FEF75) Expiratory Flow at 25% of volume remaining (FEF75) Dimensions 162 x 61 x 30mm Weight 152g Display 128 x 128 pixel graphic backlit monochrome LDC Transducer type CareFusion Uni-Directional Digital Volume Power supply 2 x AA size NiMH rechargeable cells ## 5.12 Intended Use Statement The Micro I spirometer is intended to measure the maximal volume and flow of air that can be moved out of a patient's lungs.
