Indications for Use
The SPIRO PD spirometer is intended to be used by a patient under the instruction of a physician or respiratory therapist to test lung function in child, adolescent and adult. It is also intended to be used as a single-patient device only and can be used in the home, factory, hospital or physician's office. The SPIRO PD spirometer is indicated for the following age groups: 2-12 years Child 13-21 years Adolescent 22 and over- Adult
Device Story
SPIRO PD is a handheld, battery-powered diagnostic spirometer for measuring patient breath flow and volume. It uses a turbine transducer to convert mechanical rotation—caused by exhaled air—into electrical signals via infrared light interruption. The device is intended for single-patient use in homes, clinics, or hospitals. Patients operate the device under physician or respiratory therapist instruction. The device processes flow data to calculate pulmonary parameters (FVC, FEV1, FEV1/FVC, PEF, FEF 25-75%) and estimates lung age. Results, including flow/volume curves and severity indices, are displayed on a color touchscreen LCD. Data can be downloaded to a computer for review. By providing objective lung function metrics and symptom scores, the device aids healthcare providers in monitoring respiratory health and making clinical decisions regarding conditions like asthma or COPD.
Clinical Evidence
No clinical data was collected or assessed. Substantial equivalence was established through bench testing, including electrical safety (IEC 60601-1, -1-2, -1-4, -1-6), biocompatibility (ISO 10993), and a human factors study (n=45) demonstrating 92.5% ease-of-use and 97% label comprehension across all age groups.
Technological Characteristics
Handheld, battery-powered (3.7V Li-ion) diagnostic spirometer. Flow measurement via digital turbine transducer with infrared interruption. Features 320x240 color touchscreen LCD. Dimensions: 200x96x40mm; weight: 256g. Adheres to ATS guidelines. Predictive models: NHANES III. Biocompatibility per ISO 10993. Electrical safety per IEC 60601-1 series. Connectivity: data download to PC.
Indications for Use
Indicated for lung function testing in children (2-12 years), adolescents (13-21 years), and adults (22+ years) under the instruction of a physician or respiratory therapist.
Regulatory Classification
Identification

#### Device Description
The SPIRO PD spirometer is an instrument that acquires mechanical signals and processes the information provided by the signal related to the pulmonary function. For processing purposes, mechanical signals must be changed to electrical signals. The devices responsible for this change are called transducers. The SPIRO PD has a Turbinetype transducer. The turbine transducer performs transduction in two stages: The volume to be measured crosses the turbine vane and records its rotation that is proportional to that Volume, this rotation is detected by the interrupting of a beam of infrared light, the sensor of which converts the light received into a digital-type electrical signal.
