Embolism can occur when an embolus, or blood clot, forms around a heart valve that is not working properly, or is released within the arteries to the brain, causing a stroke. The effects of a stroke may include temporary dizziness. However, if the embolus travels to the vestibular system, it can cause severe dizziness.
Step 6: Position the portable air conditioner a few feet from the window. Connect the exhaust hose (if you need to lengthen it, pull gently) to the opening in the window panel fixture. Depending on the model, the hose should lock, twist or snap into place. Step 7: Plug in the power cord and prepare to cool off.
20' x 20' = 400 square feet. 400 square feet = at least 12,000 BTUs. As such, if your room measures 400 square feet, you will need a portable air conditioner that offers 12,000 BTUs of cooling.However, please note that the figures in the chart above are estimates based on average room conditions in a moderate climate. BTU is a unit of energy that is commonly used in the power, steam generation, and heating and air conditioning industries. Generally speaking, a portable air conditioner's BTU rating describes its power and cooling capacity. Naturally, the higher the BTUs, the stronger the portable AC.
