摘要

INTRODUCTION: Congestion is common during spaceflight, and congestion medications have been used on the International Space Station (iSS). While congestion has been attributed to fluid shifts, fluid equilibrium is reached during the first week of flight but congestion still continues to" be reported. Congestion has anecdotally been reported in relation to ISS CO_2 levels; this evaluation was undertaken to determine if an association exists. METHODS: Reported headaches (HA), congestion symptoms, and CO_2 levels were obtained for ISS expeditions 2-31, and time-weighted means and single-point maxima were determined for 24-hour (24hr) and 7-day (7d) periods prior to each weekly private medical conference. Multiple imputation addressed missing data, and logistic regression modeled the relationship between probability of reported event of congestion or HA and CO_2 levels, adjusted for possible confounding covariates.The first seven days of flight were not included to control for fluid shifts. Data were evaluated to determine the CO_2 concentration required to maintain the risk of congestion below 1 % to allow for direct comparison with a previously published evaluation of CO2 concentrations and HA.
