The Relationship Between Peak Oxygen Consumption and Pulmonary Function Indices: Measured by Spirometry and Allometry Equation in Male Students

Purpose: Allometry is a method to express the relationship between physiological and anatomical variables. It can be used to measure the vital capacity through mathematical equations. This study aimed at evaluating lung function indices to estimate the maximal aerobic power by respiratory gas analysis device and the allometric equation. Methods: This study was a descriptive and correlational r...

Stimulation of oxygen consumption and superoxide anion production in pulmonary macrophages by N-formyl methionyl peptides.

A number of metabolic changes occur when phagocytic cells (i.e., polymorphonuclear neutrophils (PMN)) interact with certain soluble and particulate stimuli (reviewed [l-4]). These metabolic changes include an increase in oxygen consumption, stimulation of hexose monophosphate shunt activity, superoxide anion production (O;), hydrogen peroxide prnduction and chemiluminescence. It has been propos...

Prospective study of cured meats consumption and risk of chronic obstructive pulmonary disease in men.

Cured meats are high in nitrites. Nitrites generate reactive nitrogen species that may cause damage to the lung. The objective is to assess the relation between frequent consumption of cured meats and the risk of newly diagnosed chronic obstructive pulmonary disease (COPD). Between 1986 and 1998, the authors identified 111 self-reported cases of newly diagnosed COPD among 42,915 men from the He...

The pulmonary physician in critical care c 2: Oxygen delivery and consumption in the critically ill

Early detection and correction of tissue hypoxia is essential if progressive organ dysfunction and death are to be avoided. However, hypoxia in individual tissues or organs caused by disordered regional distribution of oxygen delivery or disruption of the processes of cellular oxygen uptake and utilisation cannot be identified from global measurements. Regional oxygen transport and cellular uti...
