Causes of shortness of breath includeasthma, bronchitis, pneumonia, pneumothorax, anemia, lung cancer, inhalation injury, pulmonary embolism, anxiety, COPD, high altitude with lower oxygen levels, congestive heart failure, arrhythmia, allergic reaction, anaphylaxis, subglottic stenosis, interstitial lung d...
Again, these space suits are designed only for emergency use -- in case the cabin pressure fails or the astronauts have to eject from the spacecraft at high altitude during liftoff or re-entry. We will discuss the current space suit (Extravehicular Mobility Unit or EMU) that is used for ...

Atmospheric pressure decreases with increasing altitude. 1. How this would impact a mountaineer as they ascend mount Everest? 2. As the atmospheric pressure changes, how and why would it affect gas exchange? How is a lentic ecosystem different from a lotic ecosystem? How do plants adapt to a...
have to request that from the air traffic controller who knows and also sees all the planes in the area on the radar. Vertical separation between planes has to remain, so sometimes there is a plane somewhere that we need to create distance horizontally with until we can change the al...
How well you’ll cope on a mountain has little to do with how fit you are. Credit: wynand van poortvliet unsplash, CC BY-SA Every year, thousands of people travel to high-altitude environments for tourism, adventure-seeking, or to train and compete in various sports. Unfortunately, these ...
Students have had to stay at home and take classes online. Basic outdoor activities have also been cancelled. Families have had to face the changes forced by the pandemic and cope with the new norm. How can we keep our families active and happy when normal life has...
The rapid climate change on the QTP has led to obvious spatial variability in the distribution of SOS, which is mainly manifested by the obvious delay of SOS in the high-altitude areas in the southwest and the trend of advancement in most other regions, while the interannual variation of SOS...
Just check out this chart below to see for yourself: When it becomes too difficult for the body to keep up with the oxygen levels your cells need, that’s when altitude sickness begins to occur. High altitude is considered anything over 5000 feet (1500 meters) above sea level. Altitude si...
A study published May 13 in the journalSciencereported that Tibetans are genetically adapted to high altitude. Now a separate study pinpoints a particular site within the human genome — a genetic variant linked to low hemoglobin in the blood — that helps explain how Tibetans cope with low-oxyg...
