Effects of alveolar dead-space, shunt and V/Q distribution on respiratory dead-space measurements.
BACKGROUND Respiratory dead-space is often increased in lung disease. This study evaluates the effects of increased alveolar dead-space (Vd(alv)), pulmonary shunt, and abnormal ventilation perfusion ratio (/) distributions on dead-space and alveolar partial pressure of carbon dioxide (Pa(co(2))) calculated by various methods, assesses a recently published non-invasive method (Koulouris method) ...

Background. Respiratory dead-space is often increased in lung disease. This study evaluates the effects of increased alveolar dead-space (VDalv), pulmonary shunt, and abnormal ventilation perfusion ratio ( _ V= _ Q) distributions on dead-space and alveolar partial pressure of carbon dioxide (PACO2) calculated by various methods, assesses a recently published non-invasive method (Koulouris metho...
متن کاملAspiration of dead space in the management of chronic obstructive pulmonary disease patients with respiratory failure.
INTRODUCTION Carbon dioxide clearance can be improved by reducing respiratory dead space or by increasing the clearance of carbon-dioxide-laden expiratory gas from the dead space. Aspiration of dead space (ASPIDS) improves carbon dioxide clearance by suctioning out (during expiration) the carbon-dioxide-rich expiratory gas while replacing the suctioned-out gas with oxygenated gas. We hypothesiz...
متن کاملThe respiratory dead space measured by single breath analysis of oxygen, carbon dioxide, nitrogen or helium.
Fowler ( 1 ) estimated the respiratory dead space in man by recording simultaneously and continuously the nitrogen concentration and the volume flow at the mouth during a single expiration, following a breath of oxygen. Such an expiration may be divided into three phases. In the first part of expiration there is virtually no nitrogen. This is followed by an S-shaped rise in nitrogen concentrati...
