Clinical Trial Summary

The goal of this observational study is to compare pulmonary health parameter measurements from the VQm PHM™ to existing clinical measurements. The main questions it aims to answer are:

• Confirm the performance of non-invasive pulmonary health parameter shunt fraction value found on the VQm PHM™ when compared to available reference measurements.

• Confirm the performance of non-invasive pulmonary health parameter pulmonary blood flow, functional residual capacity and physiological dead space found on the VQm PHM™ when compared to available reference measurements.

Description:

This is a multi-site, international, prospective, non-blinded, non-randomized, observational study. This study aims to compare measurements from the VQm PHM™ to existing clinical measurements, assess safety of the device and determine effects that standard clinical events have on the VQm PHM™ measurements. This study does not include changes to clinical care based on measurements from the VQm PHM™. Each patient will serve as their own control.

Intervention

Device:
• VQm Pulmonary Health Monitor™
The VQm Pulmonary Health Monitor™ (may be referred to as the VQm PHM™) is a a Class IIa, Health Canada approved medical device used as an adjunct monitor and is non-life supporting, providing clinicians with measurements of pulmonary function parameters of mechanically ventilated adult patients. The measurements provided are: Pulmonary Blood Flow (PBF) Shunt Fraction (Qsi) Dead space (VD): Functional Residual Capacity (FRC)
