Sleep and Respiratory Physiology in Adults
Clinics in Chest Medicine, 2014 Respiration during sleep is determined by metabolic demand; respiratory drive is determined by a central respiratory generator. Changes in pharyngeal dilator muscle tone resulting in increased upper airway resistance and collapsibility contribute to ...

Emergency Medicine Clinics of North America, 1989
A basic review is presented of the anatomy and physiology of the airways and the alveolar - capillary interface. Lung volumes are defined, as are terms used in pulmonary function testing, and alveolar ventilation is discussed. Five common mechanisms of arterial hypoxemia are explored and some common examples are presented, and the value and limitations

Abstract This chapter synthesizes the major concepts underlying the control of breathing in sleep relevant to normal physiology and sleep-related breathing disorders. It identifies the central organization of the respiratory network and explains the key concepts and principles underlying the differential effects of sleep on respiratory ...

Evaluation of chest ultrasound integrated teaching of respiratory system physiology to medical students [PDF]
American Journal of Physiology - Advances in Physiology Education, 2017 Ultrasound imaging is a widely used diagnostic technique, whose integration in medical education is constantly growing. The aim of this study was to evaluate chest ultrasound usefulness in teaching respiratory system physiology, students' perception of ...

Respiratory Physiology at Altitude
Journal of the Royal Army Medical Corps, 2011The changes in respiratory physiology that occur with increasing altitude are driven by the fall in the partial pressure of oxygen that occurs with decreasing barometric pressure. At altitude, respiratory system changes occur which impact on each step of the oxygen cascade that occurs within the body.

RESPIRATORY PHYSIOLOGY IN PREGNANCY
Clinics in Chest Medicine, 1992In conclusion, it is important to appreciate the anatomic and physiologic adaptations in pregnancy in order to accurately diagnose and treat cardiopulmonary disease states in the gravid woman. Without knowing what constitutes normalcy in pregnancy, inappropriate diagnosis and interventions may occur.

Respiratory Physiology of Seizures
Journal of Clinical Neurophysiology, 2009Comonitoring of seizures and respiratory function with pulse oximetry has shown that ictal respiratory changes (IRCs) accompany tonic-clonic convulsions and even partial seizures, especially those of temporal lobe origin. IRCs occur in children and adults, and diminished central drive is frequent, although peripheral obstruction is observed ...

Pediatrics, 1963
It is to be hoped that the British Medical Bulletin is sufficiently known and appreciated on this side of the Atlantic. The appearance of numbers on hypothermia, fetal and neonatal physiology (excellently edited by R. A. McCance), human genetics, and the adrenal cortex, as four of the six issues in the last 2 years, indicates how timely are the ...

Respiration provides oxygen (O2) and removes carbon dioxide (CO2) for the body. An extraordinary anatomic arrangement of functional units (the alveoli) delimited by extra-thin walls (epithelium and endothelium) creates the interface for gas exchange between air and blood.
