Abstract:

The effects of smoking withdrawal on complex time-shared performance and physiological responses were studied at a simulated aircraft cabin altitude of 6,500 ft. Seventeen habitual smokers, nine women and eight men 23 to 59 years of age, served as subjects. Time-shared performance of monitoring, tracking, mental arithmetic, and problem solving tasks were measured by the Civil Aeromedical Institute CAMI Multiple Task Performance Battery MTPB in two 4-h test sessions, one in which smoking was permitted at 12-h intervals and a no-smoking session. Corollary physiological measurements involved urinary hormones epinephrine, norepinephrine, and 17-ketogenic steroids, carboxyhemoglobin levels COHb, and heart rate HR. Overall composite scores for MTB performance revealed decrements during withdrawal which were statistically significant p .05 decrement in tracking and a tendency toward longer reaction times in one monitoring task during withdrawal. These performance decrements were associated with significantly lower HR p .001 and lower p .05 ratings of attentiveness during withdrawal from smoking. These findings support a cautious approach to the prohibition of smoking on the flight deck for aircrew members. Author
