Investigation of the Effects of Hypocapnia upon Cerebral Haemodynamics in Normal Volunteers and Anaesthetised Subjects by near Infrared Spectroscopy (NIRS)
The effect of alterations in arterial carbon dioxide tension (PaCO2) upon the cerebral blood vessels was first described in 1930 by Wolff and Lennox and quantified in 1948 by Kety and Schmidt. Since then many stu...

An Automated System for the Measurement of the Response of Cerebral Blood Volume and Cerebral Blood Flow to Changes in Arterial Carbon Dioxide Tension Using Near Infrared Spectroscopy
Since it was first described by Jobsis in 1977, near infrared spectroscopy (NIRS) has become widely used as a non invasive technique for monitoring the blood and tissue oxygenation of intact organs and to date...

Measurement of Changes in Cerebral Haemodynamics During Inspiration and Expiration Using Near Infrared Spectroscopy
Near infrared spectroscopy (NIRS) has been employed over the last decade to monitor the changes in tissue oxygenation of intact organs (Jobsis 1977, Brazy et al. 1985, 1986, Ferrari et al. 1986a, 1986b, Hampso...
