Providing supplemental oxygen is an essential element of emergency care. Anyone expected to use a medical oxygen device can benefit from this program. The text effectively outlines the importance and

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.

CLICK HERE to download the first 50 pages from Climbing the Seven Summits * First and only guidebook to climbing all Seven Summits * Full color with 125 photographs and 24 maps including a map for each summit route * Essential information on primary climbing routes and travel logistics for mountaineers, with historical and cultural anecdotes for armchair readers Aconcagua. Denali. Elbrus. Everest. Kilimanjaro. Kosciuszko. Vinson. To a climber, these mountains are known as the Seven Summits* -- the highest peaks on each continent. If you've ever dreamed of climbing Denali or Everest, or joining the even more exclusive "Seven Summiters " club, then Climbing the Seven Summits is the guidebook you need to turn your dream into reality. With Mike Hamill as your guide, you will discover different approaches to tackling the list, as well as details on what you'll need to plan an expedition and what to expect from each climb. For each mountain you'll learn about documents and immunizations, expedition costs, training, guiding options, climbing styles, best seasons, essential gear, day-by-day itineraries, summit routes, maps showing approaches and camps, regional natural history, cultural notes, and even post-climb activities like going on safari in Africa or wine-touring in South America. Throughout you'll also find helpful and inspiring stories from the likes of Conrad Anker, Vern Tejas, Damien Gildea, Eric Simonson, and other famed climbers. Special insider tips from Hamill, based on his years of experience, as well as full-color photographs of each peak round out this collectible guidebook. And, because there remains some controversy about whether Kosciuszko in Australia or Carstenz Pyramid on the island of New Guinea is the "seventh summit," this guidebook to the Seven Summits actually covers eight mountains! *Within mountaineering circles there is debate over which peaks are considered the official Seven Summits. For the purposes of this guidebook, the Seven Summits are based on the continental model used in Western Europe, the United States, and Australia, also referred to as the 'Bass list.'

Compartment syndrome is a complex physiologic process with significant potential harm, and though an important clinical problem, the basic science and research surrounding this entity remains poorly understood. This unique open access book fills the gap in the knowledge of compartment syndrome, re-evaluating the current state of the art on this condition. The current clinical diagnostic criteria are presented, as well as the multiple dilemmas facing the surgeon. Pathophysiology, ischemic thresholds and pressure management techniques and limitations are discussed in detail. The main surgical management strategy, fasciotomy, is then described for both the upper and lower extremities, along with wound care. Compartment syndrome due to patient positioning, in children and polytrauma patients, and unusual presentations are likewise covered. Novel diagnosis and prevention strategies, as well as common misconceptions and legal ramifications stemming from compartment syndrome, round out the presentation. Unique and timely, Compartment Syndrome: A Guide to Diagnosis and Management will be indispensable for orthopedic and trauma surgeons confronted with this common yet challenging medical condition.

The purpose of this guidance document is for the appropriate selection procurement utilization and maintenance of oxygen concentrators. This document also focuses on recommendations for the appropriate use and maintenance of oxygen concentrators in an effort to increase the availability management and quality of oxygen concentrators and ultimately to improve health outcomes in LRS. This document is intended to serve as a resource for the planning and provision of local and national oxygen concentrator systems for use by administrators clinicians and technicians who are interested in improving access to oxygen therapy and reducing global mortality associated with hypoxaemia.

"Hypoxaemia is a major contributor to child deaths that occur worldwide each year; for a child with pneumonia hypoxaemia increases the risk of death by up to 5 times. Despite its importance in virtually all types of acute severe illness, hypoxaemia is often not well recognized or well managed, more so in settings where resources are limited. Oxygen therapy remains an inaccessible luxury for a large proportion of severely ill children admitted to hospitals in developing countries. This is particularly true for patients in small district hospitals, where, even if some facility for delivering oxygen is available, supplies are often unreliable and the benefits of treatment may be diminished by poorly maintained, inappropriate equipment or poorly trained staff with inadequate guidelines. Increasing awareness of these problems is likely to have considerable clinical and public health benefits in the care of severely ill children. Health workers should be able to know the clinical signs that suggest the presence of hypoxaemia and have more reliable means of detection of hypoxeamia. This can be achieved through more widespread use of pulse oximetry, which is a non-invasive measure of arterial oxygen saturation. At the same time oxygen therapy must be more widely available; in many remote settings, this can be achieved by use of oxygen concentrators, which can run on regular or alternative sources of power. Having effective systems for the detection and management of hypoxaemia are vital in reducing mortality from pneumonia and other severe acute illnesses. Oxygen therapy is essential to counter hypoxaemia and many times is the difference between life and death. This manual focuses on the availability and clinical use of oxygen therapy in children in health facilities by providing the practical aspects for health workers, biomedical engineers, and administrators. It addresses the need for appropriate detection of hypoxaemia, use of pulse oximetry, clinical use of oxygen and delivery systems and monitoring of patients on oxygen therapy. In addition, the manual addresses practical use of pulse oximetry, and oxygen concentrators and cylinders in an effort to improve oxygen systems worldwide."--Publisher's description.
