**Guidelines for flexiVent Techniques & Measurements**

**\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** 

 

**Understanding the flexiVent Measurements**

The flexiVent combines all industry-standard measurements in one device, meaning you don't need to choose between Resistance / Compliance and PV Loops, or the Forced Expirations outcomes.

This document provides technical as well as physiological descriptions of the [flexiVent](https://www.scireq.com/flexivent/) perturbations / manoeuvres used to assess lung function in preclinical respiratory models. The usefulness of each family of pertubations / manoeuvres is also highlighted and examples of [research applications](https://www.scireq.com/applications/) where each can be used are included:

 

- Deep Inflation
- Single Frequency FOT: Resistance & Compliance
- Broadband FOT: Quick Prime, ***unique to the flexiVent***
- Pressure - Volume Loops
- Force Expired Manoeuvre (NPFE)
- Lung Volumes: ***unique to the flexiVent***
