Table 4 Comparison of cerebral blood flow velocities at high altitude

From: Smoking is associated with the incidence of AMS: a large-sample cohort study

Index

Non-smoker (n = 130)

Smoker (n = 225)

Systolic velocity

105.98 ± 17.06

101.12 ± 14.27a

Diastolic velocity

49.78 ± 10.19

47.04 ± 8.73a

Mean velocity

69.64 ± 12.96

66.43 ± 11.04a

  1. aP < 0.05 compared with non-smokers. Due to technical problems, only a subset of subjects (n = 355) underwent cerebral blood flow velocity tests.
