Overview

Acute hypoxia may impair executive/inhibitory and somatosensory processing; hypothesis-generating, needs confirmation before clinical relevance.

Structured PICO

Does acute hypoxia impair cognitive processing in healthy subjects?

P
Population
15 healthy subjects
I
Intervention
Acute normobaric hypoxia (breathing 12% O2)
C
Comparator
Normoxia (breathing room air)
O
Outcome
Peak amplitudes and latencies of Go-P300 and No-go-P300 (electroencephalographic event-related potentials)surrogate

Acute normobaric hypoxia impairs neural activity in motor executive and inhibitory processing without affecting somatosensory processing.
