Vivid animation and real-life examples demonstrate the respiration process, including the transfer of oxygen into the bloodstream and the effect of exercise on the respiratory system.  

Exercise tolerance test(aka Exercise ECG testing) Used to: Confirm the diagnosis of angina Give an indication of the severity of CAD – thus allowing you to asses risk. This can be done either in a patient with CAD, or in somebody with CAD who has had a previous MI.    

A 15 year old girl who had been previously fit and well presented to the child and adolescent mental health services (CAMHS) team with weight loss, irregular menstrual periods, excessive exercise, restriction of energy intake during the day, and binging during the evening, followed by vomiting. Her symptoms had been present for a year, since her father had experienced a myocardial infarction. Clinically her symptoms were in keeping with anorexia nervosa, as shown by her completed eating disorder questionnaire.1 Her body mass index (BMI) was 16 and her weight for height was 85% of the median (50th centile) for age and sex. She had a distorted body image, believing her stomach and ankles were too fat, and she had an extreme fear of gaining weight.  

England’s Department of Health must be prepared to loosen its grip on the management of the NHS and allow new organisations the freedom to perform their roles, a new survey has found.  

Medical Research Council dyspnoea scale in COPD 1: Not troubles by breathlessness except on strenuous exercise. 2: Short of breath when hurrying or walking up a slight hill. 3: Walks slower than contemporaries on the level because of breathlessness, or has to stop for breath when walking at own pace. 4: Stops for breath after about 100, or after a few minutes on the level.

Lack of exercise affects a woman’s risk of developing heart disease more than other known risk factors, including being overweight, new research has shown.1  

Athletes beware - endurance training may make it more likely that you will need a pacemaker, scientists believe, although exercise is still good for us, they say.

Exercise-associated hyponatremia (EAH) typically occurs during or up to 24 hours after prolonged physical activity, and is defined by a serum or plasma sodium concentration below the normal reference range of 135 mEq/L. It is also reported to occur in individual physical activities or during organized endurance events conducted in austere environments in which medical care is limited or often not available, and patient evacuation to definitive care is often greatly delayed. Rapid recognition and appropriate treatment are essential in the severe form to ensure a positive outcome. Failure in this regard is a recognized cause of event-related fatality. In an effort to produce best practice guidelines for EAH in the austere environment, the Wilderness Medical Society convened an expert panel. The panel was charged with the development of evidence-based guidelines for management of EAH. Recommendations are made regarding the situations when sodium concentration can be assessed in the field and when these values are not known. These recommendations are graded based on the quality of supporting evidence and balance between the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians.  

This study was conducted to better define the pathophysiology, risk factors, and therapeutic approach to exercise-associated hyponatremia. Medical records from all participants in the 1998 Suzuki Rock ‘N’ Roll Marathon® who presented to 14 Emergency Departments (EDs) were retrospectively reviewed to identify risk factors for the development of hyponatremia. Hyponatremic patients were compared to other runners with regard to race time and to other marathon participants seen in the ED with regard to gender, clinical signs of dehydration, and use of nonsteroidal anti-inflammatory drugs (NSAIDs). An original treatment algorithm incorporating the early use of hypertonic saline (HTS) was evaluated prospectively in our own ED for participants in the 1999 marathon to evaluate improvements in sodium correction rate and incidence of complications. A total of 26 patients from the 1998 and 1999 marathons were hyponatremic [serum sodium (SNa) ≤135 mEq/L] including 15 with severe hyponatremia (SNa ≤ 125 mEq/L). Three developed seizures and required intubation and admission to an intensive care unit. Hyponatremic patients were more likely to be female, use NSAIDS, and have slower finishing times. Hyponatremic runners reported drinking “as much as possible” during and after the race and were less likely to have clinical signs of dehydration. An inverse relationship between initial SNa and time of presentation was observed, with late presentation predicting lower SNa values. The use of HTS in selected 1999 patients resulted in faster SNa correction times and fewer complications than observed for 1998 patients. It is concluded that the development of exercise-associated hyponatremia is associated with excessive fluid consumption during and after extreme athletic events. Additional risk factors include female gender, slower race times, and NSAID use. The use of HTS in selected patients seems to be safe and efficacious.
