NCT06548386

Brief Summary

The goal of this study is to assess the clinical feasibility of a novel, reusable, low cost gas analyzer that detects breath in chest drains in order to diagnose and heal air leaks. The investigators have developed prototype gas analyzers that attach to the outlet of any analog chest drain, and can be connected temporarily to the sampling port. They detect breath by measuring CO2, O2, and pressure, in order to supplement the information provided by the bubbles in the water seal.

Outcome Measures

Primary Outcomes (1)

  • Accuracy alone

    Whether gas analysis can accurately assess for air leak

    One year

Secondary Outcomes (1)

  • Using VI as well

    One year

Interventions

Patients enrolled in this study will undergo both VI and pleural gas analysis to assess for air leak following surgical chest tube placement. For pleural gas analysis, an outlet gas analyzer will be kept on the outlet port of the chest drain for the entire duration of time that a chest tube is in place. We plan to collect both continuous data, looking for intermittent spikes and gas changes, along with episodic data collected during specific air leak assessments. The gas analyzer may better be able to measure an air leak during these specific procedures conducted twice per day, but it will also be used at the outlet port of the chest drain the rest of the time to continuously check for an air leak throughout the hospital stay.
