Abstract Knowledge of respiratory mechanics is fundamental for correct use of mechanical ventilation and full understanding of the impact of lung disease during anesthetic administration. The role of the respiratory system is to deliver oxygen to cells so that respiration can occur.

Design of a Lung Simulator for Teaching Lung Mechanics in Mechanical Ventilation
Archivos de Bronconeumología ((English Edition)), 2007Over the last 10 years, noninvasive ventilation has become a treatment option for respiratory insufficiency in pulmonology services. The technique is currently included in pulmonology teaching programs. Physicians and nurses should understand the devices they use and the interaction between the patient and the ventilator in terms of respiratory ...

Canadian Journal of Medical Sciences, 1952
A practical mechanical heart and lung is described in which glass syringes are used to replace the ventricles. The pistons of the syringes are operated by a special cam rather than a simple crank. Thus the volume changes in the syringes are made to follow those of the mammalian ventricles.

Mechanical properties of the lung
British Journal of Diseases of the Chest, 1960Summary (1) The pressures developed at the mouth at different chest volumes, when relaxing against an obstruction, characterise the elastic properties of the lung and chest wall. During movement additional pressures are necessary to overcome frictional forces due to the frictional resistance of the lungs and chest wall and the resistance to ...

Alterations of the mechanical properties of the respiratory system are so constant in adult respiratory distress syndrome (ARDS) to be considered an integral part of its definition [1].

Clinics in Chest Medicine, 1982
The adult respiratory distress syndrome is pulmonary edema with low heart pressures and hypoxemia. Based on experimental models of the human disease, it is likely that functional injury to the lung includes pulmonary vasoconstriction, a loss of hypoxic vasoconstriction, increases in resistance to airflow across the lungs, decreases in lung compliance ...

Lung remodeling mechanisms in chronic lung diseases
Current Opinion in Allergy & Clinical Immunology, 2014To summarize the new knowledge on tissue remodeling in the context of lung diseases. Tissue remodeling includes changes in cells: differentiation; response to growths factors, hormones, or environmental factors; and composition of the extracellular matrix. So, can one trigger cause them all or are they independently regulated?New evidence from clinical

Mechanisms of Acute Lung Injury
Clinics in Laboratory Medicine, 1983The role of the complement system in generating an acute inflammatory response in the lung, manifested particularly by the presence of neutrophils, and the role of these neutrophils in altering lung microvascular permeability are examined. Although it is not possible at this time to reconcile all the experimental data so as to provide a unifying ...

Mechanical impedance of the lung periphery
Journal of Applied Physiology, 1997Hantos, Z., F. Peták, Á. Adamicza, T. Asztalos, J. Tolnai, and J. J. Fredberg. Mechanical impedance of the lung periphery. J. Appl. Physiol.83(5): 1595–1601, 1997.—The mechanics of the regional airways and tissues was studied in isolated dog lobes by means of a modified wave-tube technique.

The mechanical memory of lung myofibroblasts
Integrative Biology, 2012Fibroblasts differentiate into the highly synthetic and contractile myofibroblast phenotype when exposed to substrates with an elastic modulus corresponding to pathologically stiff fibrotic tissue. Cellular responses to changes in substrate stiffness are typically analyzed after hours or days, which does not enable the monitoring of myofibroblast ...
