Whiteley J, Farmery A, Gavaghan D, Hahn C
Respir Physiol Neurobiol
. 2003 Jun;
136(1):77-88.
PMID: 12809800
We develop tidal-ventilation pulmonary gas-exchange equations that allow pulmonary shunt to have different values during expiration and inspiration, in accordance with lung collapse and recruitment during lung dysfunction (Am. J....

Br J Anaesth
. 2002 Aug;
88(6):771-8.
PMID: 12173192
Background: Measures of impairment of oxygenation can be affected by the inspired oxygen fraction. Methods: We used a mathematical model of an inhomogenous lung to predict the effect of increasing...

Whiteley J, Turner M, Baker A, Gavaghan D, Hahn C
Respir Physiol Neurobiol
. 2002 Jul;
131(3):269-84.
PMID: 12126927
We investigate the effects on arterial P(CO(2)) and on arterial-end tidal P(CO(2)) difference of six different ventilation patterns of equal tidal volume, and also of various combinations of tidal volume...

Whiteley J, Gavaghan D, Hahn C
J Theor Biol
. 2001 Apr;
209(4):431-43.
PMID: 11319892
Inert gas exchange in tissue has been almost exclusively modelled by using an ordinary differential equation. The mathematical model that is used to derive this ordinary differential equation assumes that...

Whiteley J, Gavaghan D, Hahn C
Math Biosci
. 2001 Feb;
169(2):153-72.
PMID: 11166320
In this study we investigate the equations governing the transport of oxygen in pulmonary capillaries. We use a mathematical model consisting of a red blood cell completely surrounded by plasma...

Respir Physiol
. 2000 Nov;
124(1):65-83.
PMID: 11084204
The tidal breathing model conservation of mass equations for the sinewave technique have been described for a homogeneous alveolar compartment by Gavaghan and Hahn, 1996 [Gavaghan, D.J., Hahn, C.E.W., 1996....

Collier J, McInerney D, Schnell S, Maini P, Gavaghan D, Houston P, et al.
J Theor Biol
. 2000 Nov;
207(3):305-16.
PMID: 11082301
After many years of research, the mechanisms that generate a periodic pattern of repeated elements (somites) along the length of the embryonic body axis is still one of the major...

J Theor Biol
. 2000 Jun;
204(4):575-85.
PMID: 10833357
The coupled conservation of mass equations for oxygen, carbon dioxide and nitrogen are written down for a lung model consisting of two homogeneous alveolar compartments (with different ventilation-perfusion ratios) and...

Whiteley J, Gavaghan D, Hahn C
J Theor Biol
. 1999 Dec;
201(4):271-9.
PMID: 10610756
We investigate the effect of the width of ventilation-perfusion distributions on arterial blood oxygen content. We assume that the perfusion within the alveolar volume is a continuous function of ventilation-perfusion...

J Appl Physiol (1985)
. 1999 Jul;
87(1):161-9.
PMID: 10409570
The tidal breathing lung model described for the sine-wave technique (D. J. Gavaghan and C. E. W. Hahn. Respir. Physiol. 106: 209-221, 1996) is generalized to continuous ventilation-perfusion and ventilation-volume...
