70 yr old female with pneumonia
high altitude causes vessels in lungs to constrict, which increases pressure in lungs, which leads to fluid leakage from vessels into the alveoli
Moved to Denver, CO from Fort Worth, TX (increased altitude)
Effects of symptoms
wet, wheezy cough caused by pulmonary edema
fluid in lungs caused by
fast, shallow breathing caused by lungs not being able to bring in air at full capacity
Solubility of a gas in a liquid depends on the partial pressure of the gas in the air and the volume of the gas that dissolves in the liquid
The sum of all partial pressures is equal to the atmospheric pressure
Pressure of a gas decreases as the volume of the container increases

Partial pressure decreases at higher altitudes
Respiratory Alveolar Physiology
O2 diffuses from alveoli to capillaries across the respiratory membrane due to the partial pressure of O2 in blood being lower than the partial pressure of O2 in the alveoli. The simple squamous epithelium ct allows this diffusion. The simple cuboidal epithelium ct, which secretes surfactent, prevents alveolar collapse.
Inflammation decreases the lungs ability to adequately fill with air as it increases the pressure in the lungs which makes it harder for atmospheric air to rush in.
If left untreated, will lead to death due to O2 deprivation
This causes the cardiovascular system to try to work harder to get more O2 in body and can lead to infection spreading to the heart which will cause heart failure. The immune system is causing inflammation which is decreasing their capacity to fill with air.
Direct cause is the increased altitude which increased pressure in lungs and led to fluid leakage from the vessels into the alveoli
