Abstract

Introduction: Baseline capnographic parameters are founded upon research about environments close to the sea level, which requires their validation and standardization in high-altitude scenarios.

Objective: To determine baseline partial end-tidal (Pet) CO2 levels in surgical patients attended at Hospital Vicente Corral Moscoso, located at 2,560 meters above sea level.

Methods: An observational, descriptive and cross-sectional study was conducted in the anesthesiology and resuscitation service at Hospital Vicente Corral Moscoso, in the period from January 2019 to March 2020. A population of 534 patients included in the sample was studied.

Results: Baseline PetCO2 levels were predominantly in the range between 28-31 mmHg, with a mean of approximately 28 mmHg. Half of the patients had estimated partial pressure (PA) O2 levels between 65-69 mmHg, with an overall mean of approximately 68 mmHg. The application of the Kruskal-Wallis test evidenced a statistically significant influence of the type of surgery, mean arterial blood pressure and respiratory rate during capnography measurement over baseline PetCO2 levels.

Conclusions: Baseline PetCO2 levels in surgical patients in the city of Cuenca had a mean of approximately 28 mmHg; such values were evidenced to receive the influence, with a statistical significance, of emergency surgery, mean arterial blood pressure and respiratory frequency.
