In this study, the optimal human respiratory control model proposed earlier was modified to include the nonlinear respiratory mechanics by replacing the resistance with a lumped viscous resistance of the flow through total respiratory system, and a resistance of flow which is proportional to the power of flow rate. To evaluate the effect of the nonlinear respiratory mechanics in the optimal res...

Assessment of respiratory mechanics can play a central role in the management of critically ill patients undergoing artificial ventilation because of acute respiratory failure (ARF) [1]. This is a condition defined by a rapid deterioration in pulmonary gas exchange that may be due either to alterations in the mechanical properties of the respiratory system leading to ventilation–perfusion misma...

nasal mucosa has an extraordinary nerve supply with unique geometry that encompasses complex physiology. among these, side-specific predilections to the respiratory and autonomic centers are the interesting issues that have been raised about the consequences of the nasal irritations. the aim of the study was an evaluation of how intranasal stimulation influences lung mechanics and determines wh...

This study aimed to investigate the association between respiratory mechanics and autonomic modulation in morbidly obese patients. We evaluated 10 morbidly obese subjects (BMI=52.9±11.2kg/m(2)), aged 23-58 years. Assessment of respiratory mechanics was done by the forced oscillation technique (FOT), and cardiovascular autonomic function was recorded by heart rate variability analysis (HRV). The...
