Hypoxia might sound funny. It isn’t. He is conscious enough‚ fortunately‚ to understand what’s going on‚ but he lacks oxygen to make even the slightest move on the yoke. One might think it is easy to just muster all the strength one can and push the yoke to lower the altitude‚ however... Supplemental oxygen is available to pilots as a secondary source of oxygen usually as a pressurized mask in larger aircraft. Gradual loss of cabin pressure can go unnoticed by pilots and cause hypoxia over a period

HYPOXIA Introduction Hypoxia is simply a lack of oxygen at the tissue level of the body due to a decreased partial pressure of oxygen in the inspired air. Hypoxia is serious‚ because it may lead to death. Diseases of the blood‚ the heart and circulation‚ and the lungs may all produce some form of hypoxia. There are four types of hypoxia: (1) the hypoxic type‚ in which the oxygen pressure in the blood going to the tissues is too low to saturate the haemoglobin; (2) the anaemic type‚ in which

Hypoxia Hypoxia; sometimes referenced to as a “dead zone”is a lack of oxygen in the water. Aquatic organisms require adequate dissolved oxygen to survive. The occurrence of Hypoxia‚ or low dissolved oxygen has increased substantially. In “1960 there was 12 documented cases of U.S. Coastal areas experiencing Hypoxia‚ now there is over 300 hundred.”(Diaz & Rosenberg.2008.SAH.p11.) The inability of immobile species‚ such as mussels and oysters‚ to escape these low oxygen areas‚ makes

AVIATION FIRST AID Introduction: The aviation first aid course introduces crews to first aid in an aviation environment‚ and ensures they have basic‚ essential knowledge to treat and care for passengers. First aid is the provision of initial care for an illness or injury. It is usually performed by non-expert‚ but trained personnel to a sick or injured person

Hypoxia is the main physiological complication when ascending to high altitudes. The percentage of oxygen in the atmosphere stays the same‚ but the partial pressure and barometric pressure begin to drop on rising to a higher altitude. The level of altitude‚ rate of ascent‚ and duration of exposure all determine the body’s response to hypoxia. The physiological responses to high altitude hypoxia are divided into two categories. First there are acute responses known as accommodation‚ which refers to

Introduction First Aid is the medical care given to an ill or injured person before the arrival of professional responders. First aid is basic medical care given to an ill or injured person by a non-professional in an emergency. What is interesting is the purpose of first aid; to prevent further harm - for example‚ if someone has collapsed in the middle of a road where they might not be seen‚ you want to make sure that they won’t get hit by a car too. To preserve life - so to prevent them deteriorating

Studies of drowning and near drowning of children and adults suggest that victim survival depends on the presence of both hypothermia and the MDR‚ as neither alone can provide adequate cerebral protection during long periods of hypoxia. Future research is suggested to improve patient care. INTRODUCTION Drowning and near-drowning incidents are leading causes of mortality and morbidity in both children1 and adults2. Over the past 30 years‚ there has been considerable interest
