gforces: G-induced loss of consciousness

In GLMsData: Generalized Linear Model Data Sets

G-induced loss of consciousness

Description

Loss of consciousness induced by G-forces)

Usage

data(gforces)

Format

A data frame containing 8 observations with the following 3 variables.

Subject

the initials of the subject; a text identifier

Age

the age of the subject, in years; a numeric vector

Signs

whether the subject showed syncopal blackout-related signs: a factor with levels 0 (No) and 1 (Yes)

Details

Military pilots sometimes black out when their brains are deprived of oxygen due to G-forces during violent manoeuvres. Glaister and Miller (1990) produced similar symptoms by exposing volunteers' lower bodies to negative air pressure, likewise decreasing oxygen to the brain. The data lists the subjects' ages and whether they showed syncopal blackout related signs (pallor, sweating, slow heartbeat, unconsciousness) during an 18 minute period.

Source

The data were obtained electronically from OzDASL (http://www.statsci.org/data/). The Details above were obtained from this webpage.
