Study of the Effects of Iron Levels on the Lungs at High Altitude
NCT00952302 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 33
Last updated 2009-08-06
Summary
The study hypothesis is that body iron levels are important in determining the increase in lung blood pressure that occurs in response to low oxygen levels. The purpose of this study is to determine whether this is true at high altitude, where oxygen levels are low.
