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

A cabin pressurization system accomplishes several functions in providing passengers comfort and safety. It maintains a cabin pressure altitude of approximately 8‚000 feet at the maximum designed cruising altitude of the airplane‚ and prevents rapid changes of cabin altitude‚ which may be dangerous to the passengers and crew. In addition‚ the pressurization system

differential that exists across the respiratory surface. At higher altitudes‚ where the atmospheric pressure is lower‚ the partial pressure of oxygen is also lower. The partial pressure differential of oxygen‚ therefore‚ is also lower‚ and the organism effectively receives less oxygen when it breathes‚ even though the percentage of oxygen in the air remains constant. This lack of oxygen is why humans carry oxygen when ascending to high altitudes. Humans who live in mountainous regions‚ however‚ can become

African Sleeping Sickness Human African Trypanosomiasis‚ known as sleeping sickness‚ is a vector-borne parasitic disease. Trypanosoma which are the parasites are protozoa transmitted to humans by tsetse flies. Tsetse flies live in Africa‚ and they are found in vegetation by rivers and lakes‚ gallery-forests and vast stretches of wooded savannah. Sleeping sickness occurs only in sub-Saharan Africa‚ in regions where tsetse flies are endemic. There are many regions where tsetse flies are found‚ but

Thankfully the sickness is not created by people that is a good sign that we will know if you are that person who knows everything about the plague. The one and only way to get infected is get bitten by an infected flea on a dead rodent. The sickness first spread to China first in 1334 then spread to Europe and killed 60% of the population in Europe. The sickness is not airborne‚ so it’s not you can catch it
