Acute Mountain Sickness (AMS) is a well described disease process that occurs as a result of rapid exposure to high altitude. High altitude headache (HAH) is defined as the presence of headache in the setting of a recent increase in altitude. When HAH is associated with nausea, vomiting, fatigue,
Acute mountain sickness (AMS) is a common ailment in people venturing over 2500 meters altitude. It is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude. It presents as a collection of nonspecific symptoms, acquired at high
The number of people traveling to altitude for work or for recreation is rising, and increased media attention towards these activities has also raised the profile of altitude related illness. The most effective preventive measure for acute mountain sickness (AMS)-gradual ascent-is frequently
Acute mountain sickness (AMS) is one of three syndromes of altitude illness. It is very common when people venture over 2500 meters altitude. This illness is mainly induced by acute exposure to low partial pressure of oxygen at high altitude that will cause a pathological effect on humans. It
Introduction : very long distance mountain trail which is particularly demanding for the organism. This kind of competition is likely to have an impact on the athlete's health and / or physical integrity. It is assumed that many participants may use medication in an attempt to i) prevent and /or
Acute mountain sickness (AMS) is a constellation of symptoms including headache, sleep disturbance, fatigue, dizziness, and nausea, vomiting, or anorexia that commonly occurs in travelers ascending to altitudes above 2,500m. AMS incidence varies based on altitude and ascent profile with rates
The exact mechanisms by which AMS develops remains poorly understood. Interestingly, brain and spinal cord swelling due to low oxygen levels can also occur in the period following surgery to treat thoracic and abdominal aortic aneurysms, dangerous swellings of the major blood vessel in the body.
Enrollment:
A total of One hundred healthy male and female participants (group of 25 at a time) will be enrolled by study administrators at Owens Valley Lab, White Mountain Research Station. Pregnant women will be excluded. The study enrollment period will run for approximately 12 days over 4
Altitude affects human health and well being through its effect on tissue oxygenation by altering the partial pressure of oxygen in the gas that enters the lungs. The partial pressure of any component of a mixed gas is equal to the total pressure of the gas multiplied by the fraction of the gas that
Subjects Subjects with type 2 DM, of both genders, aged between 40 and 65 years, without coronary artery disease, characterized by a negative maximum exercise test, will be studied. This study will be carried out at the Prevention and Cardiovascular Rehabilitation Unit Unicardio, in Hospital Santa
The primary endpoint of this research study is to prove safety in healthy subjects breathing humidified hypoxic inspiratory gas mixture for 5 days.
The secondary endpoint of our study is to describe the physiological and biochemical changes during the 5-day hypoxic period and the 2 days after return
There are approximately five million pediatric surgeries performed in the United States every year, and approximately 50% of pediatric patients experience significant stress and anxiety before their surgery. High anxiety can result in increased postoperative pain, increased analgesic consumption,
