Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
The book describes how to use breathing as a medium for self-regulation and self-reflection and how balanced breathing thus helps to promote mental and physical health and alleviate symptoms resulting from imbalanced breathing. The authors describe applications of psychophysical breathing therapy in many areas of life, developed by both themselves and other professionals trained by them. The approach of the book is based on the interactional aspects between mind and body. A person's breathing style influences their relation both to themselves and to others - and vice versa, and thus mental and also physical health. A comprehensive theoretical description of the psychophysical regulation of breathing and the consequences of imbalanced breathing is complemented by material derived from the authors' extensive clinical experience. Psychological orientations used by the writers include object relations theories, and psychodynamic, cognitive, brief and group therapy theories. As a new aspect the writers introduce how breathing patterns are learnt in early interaction. The writers also acknowledge how physical factors affect and interact with psychological factors in producing imbalanced breathing.

Book Description
Lung disease affects more than 600 million people worldwide. While some of these lung diseases have an obvious developmental component, there is growing appreciation that processes and pathways critical for normal lung development are also important for postnatal tissue homeostasis and are dysregulated in lung disease. This book provides an authoritative review of fetal and neonatal lung development and is designed to provide a diverse group of scientists, spanning the basic to clinical research spectrum, with the latest developments on the cellular and molecular mechanisms of normal lung development and injury-repair processes, and how they are dysregulated in disease. The book covers genetics, omics, and systems biology as well as new imaging techniques that are transforming studies of lung development. The reader will learn where the field of lung development has been, where it is presently, and where it is going in order to improve outcomes for patients with common and rare lung diseases.

Book Description
We start life with a breath, and the process continues automatically for the rest of our lives. Because breathing continues on its own, without our awareness, it does not necessarily mean that it is always functioning for optimum mental and physical health. The opposite is true often. The problem with breathing is that it seems so easy and natural that we rarely give it a second thought. We breathe: we inhale, we exhale. What could be simpler? But behind that simple act lies a process that affects us profoundly. It affects the way we think and feel, the quality of what we create, and how we function in our daily life. Breathing affects our psychological and physiological states, while our psychological states affect the pattern of our breathing. For example, when anxious, we tend to hold our breath and speak at the end of inspiration in a high-pitched voice. Depressed people tend to sigh and speak at the end of expiration in a low-toned voice. A child having a temper tantrum holds his or her breath until blue in the face. Hyperven tilation causes not only anxiety but also such a variety of symptoms that patients can go from one specialty department to another until a wise clinician spots the abnormal breathing pattern and the patient is successfully trained to shift from maladaptive to normal breathing behavior.

This book represents an updated review of the physiology of the carotid body chemoreceptors. It contains results in the topics at the frontiers of future developments in O2-sensing in chemoreceptor cells. Additionally, this volume provides data from studies carried out in other O2-sensing tissues including pulmonary vasculature and erythropoietin producing cells. It is a prime source of information and a guideline for arterial chemoreception researchers.
