ANALYSIS OF ENVIRONMENT AND POPULATION DURING MICROSTREAM(TM) SIDE STREAM CAPNOGRAPHY UTILIZATION

R. A. Wales1


Background: Microstream side stream capnography is applied to intubated and non-intubated patients. Health care practitioners have provided information related to utilization of this technology to the manufacturer. This analysis examines 30 cases submitted for evaluation. These observations are from user’s applications wherein the outcomes are positive and the users desired to share their experiences. This analysis was undertaken to better understand Mircostream side stream capnography utility.

Method:
Reviewed data included provider submissions of previously unpublished cases. Cases were separated based on clinical environment. Populations are described within the environment. The uncovered data was submitted from 1999 – 2005 (therefore no PCA data is included).

Results: Thirty cases were uncovered representing: 1) EMS/ED, 19 cases, mean age 50, r = 4 – 88 yrs, 14 male, 5 female; 2) Ventilation, 5 cases, mean age 47.7 yrs, r = 37 wks – 78 yrs, 1 male, 4 female; 3) Sleep, 3 cases, mean age 9.6 yrs, r = 3 d – 20 yrs, 2 male, 1 female; and 4) Sedation, 3 cases, mean age 55.7 yrs, r = 13 yrs – 83 yrs, 2 male, 1 female. Thirteen patients where non-intubated and seventeen patients were intubated. One of the non-intubated patients received NPPV using a capnography filter line and full-face mask.

Conclusion:
In this evaluation of providers clinical application, EMS / ED reported the highest number of cases. Reports from EMS / ED included capnography for evaluation of chest compression, airway status, and sedation in the ED. Ventilation reporters describe capnography applications in difficult to wean, ventilator disconnect, sepsis, and one NPPV. Sleep reporters describe capnography utility in OSA, apnea, and hypoventilation. Capnography in sedation reporters describe EP lab use, non-intubated MAC use, and pediatric endoscopy to monitor ventilation response to sedation.

Conclusion:
The patient mix, 19 male, 11 female, 3 days to 88 yrs, treated in the field and in hospitals confirms extensive clinical utility of ventilation monitoring by capnography. This range of application confirms Mircostream side stream capnography has clinical value across a wide range of intubated and non-intubated patients throughout multiple environments.
