BACKGROUND: In normal subjects intravenous adenosine infusion has been shown to stimulate ventilation with a consequent fall in arterial partial pressure of carbon dioxide (Paco2), probably by an action on the carotid bodies. The objective of this st

We used single inspiratory capacity breaths of 5, 6 or 8% CO2 in air to obtain ventilatory responses in normal subjects, with ensemble averaging of repeated runs to define stimulus and response (Protocol 1). We also compared the effect of an inspirat

The partial pressure of carbon dioxide in arterial blood is an important operator in the control of breathing, by actions on peripheral and central chemoreceptors. In experiments on man we must often assume that lung alveolar PCO2 equals arterial PCO

Single breath tests have several obvious advantages. They are easy for the subject to do. They may be undetectable by the subject, if tidal volume inhalations of low inspired CO2 concentrations (FICO2) are given. The short duration of the response ma

The importance of carbon dioxide in the control of ventilation during exercise was tested by emptying CO 2 stores by voluntary hyperventilation. Healthy subjects were studied after 3 min hyperventilation down to an end-tidal P CO 2 of about 20 mmHg o

1. We used digital filtering techniques and segmental analysis to dissect a series of respiratory variables into three components: (a) outlying values, including deep breaths or sighs; (b) random variation; (c) non-stationary baseline variation. 2. R

Three normal subjects performed rest--exercise transitions on a cycle ergometer, from rest to unloaded pedalling (0 W), 50, 100 and 150 W. Each experiment was performed in triplicate, with randomized work load order, in two sessions. Ventilation was

Summary In this paper, a comprehensive mathematical model of the human respiratory system is presented. This is capable of reproducing events occurring within the respiratory cycle and can be used as a test-bed for examining alternative hypotheses re

We bench-tested a commercially available instrument for measuring respiratory impedance (Siregnost FD5: Siemens) and found that resistance (R) and phase changes were accurately recorded in models. In a single human subject, total respiratory resistan
