Assessment of Ventilation Using Respiratory Volume Monitor Compared to Capnography During Intravenous Sedation
Assessment of Ventilation Using Respiratory Volume Monitor During Sedation With Intravenous Propofol as Compared to Capnography in Patients Receiving Intravenous Sedation.

Detailed Description
Rationale for Proposed Research: Continuous respiratory monitoring using the ExSpiron System will be particularly beneficial to patients receiving intravenous propofol breathing spontaneously with natural airway. Assessment and management of respiratory function and early intervention when indicated is a multifaceted, complex task often complicated by the unavailability of a cohesive and continuous monitoring system to guide clinical decisions. The ExSpiron system is designed for these patients and is intended to address some of the limitations of the current generation of hospital monitors and to provide healthcare providers with continuous real-time data regarding the patient's respiratory status. Recent RVM data has shown that stratification of patients based on the MV % of predicted, prior to opioid dosing has made it possible to identify patients who are at risk for further decrease in MV and opioid-induced respiratory depression (OIRD).
- In the spontaneously breathing, non-ventilated patient, current monitoring devices do not provide continuous, objective non-invasive, continuous real time information of important respiratory parameters such as TV, MV and RR.
- Current monitoring of non-intubated patients mostly relies on oximetry data, subjective clinical assessment and occasionally EtCO2 measurements. In appropriate clinical settings, the ExSpiron system can provide direct quantitative measure of ventilation parameters for use in clinical assessment and trend prediction as well as response to medications and other interventions.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in minute ventilation, tidal volume, and end-tidal carbon dioxide following propofol
Time Frame: Starting approximately 10 min prior to colonoscopy and continuing until end of colonoscopy (average time: 45-60 minutes)
|
Minute ventilation (MV) and tidal volume (TV) measured by the Respiratory Volume Monitor will be reported as percent of baseline established during normal breathing prior to sedation.
The percent decrease in MV and TV following propofol will be compared to changes in end-tidal CO2 measured by capnography.
The amount of time between propofol doses and changes in MV and TV and EtCO2 will be quantified and compared.

Starting approximately 10 min prior to colonoscopy and continuing until end of colonoscopy (average time: 45-60 minutes)

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of Respiratory Rate measurement by Respiratory Volume Monitor and Capnography
Time Frame: Starting approximately 10 min prior to colonoscopy and continuing until end of colonoscopy (average time: 45-60 minutes)
|
Respiratory rate measurements from the respiratory volume monitor and capnography will be compared.
The percent time that a respiratory rate reading is available will be quantified and compared.
|
Starting approximately 10 min prior to colonoscopy and continuing until end of colonoscopy (average time: 45-60 minutes)
