Spirometry Focused Feature Optimization

Spirometry – Lung Function Testing

A spirometer is a vital tool used to diagnose and manage many different types of lung diseases.  Spirometry products require high performance differential pressure sensors to accurately diagnose a patient’s lung functions. Additionally, these handheld units must provide highly accurate readings regardless of how the unit is positionally held. Today, additional measurements are typically required to ensure accurate results due to unstable sensor zero functionality. Positional sensitivity remains an ongoing issue with competing differential pressure sensing technology.

Advancements made possible and improved with Superior Sensor’s NimbleSense architecture minimize errors due to positional sensitivity issues. Proprietary Z-Track technology has been added to virtually eliminate zero drift enabling more effective patient diagnosis.

Spirometry provides a way to test a patient’s lung functions. It measures the lung capacity and volume under various test conditions. Some of the most common measurements are:

 

  • Forced Vital Capacity (FVC) which is the largest amount of air that you can blow out after you take your biggest breath
  • Forced Expiratory Volume (FEV1) which is the amount of air you can blow out of your lungs in the first second of exhalation.  
  • PEF (Peak Expiratory Flow), MVV (Maximum Voluntary Ventilation), TLC (Total Lung Capacity), and others enable doctors to identify and treat the various lung diseases.

For example, the value of FVC together with FEV1 can help diagnose the type of lung disease present. 

A low FEV1 value indicates that there is a blockage in the air flow out of the lungs – a critical item to be monitored for COPD (chronic obstructive pulmonary disease) patients. Spirometry is thought to be the most reliable way to test your lungs for COPD and asthma. Additionally, Spirometry testing determines the severity of the disease and is done to cross check the efficacy of a given lung treatment. 

Technology Optimizations for Spirometry
