Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) reaches temperatures of 300 °C (572 °F) to 450 °C (842 °F).
Symptoms of Teflon Flu. According to the Poison Center, people can feel the following symptoms after inhaling fumes from PTFE-coated products: headache. fever or elevated temperature. shivering or ...
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from ... “This inhalation of a foreign substance elicits an immune ...
A recent record number of cases of polymer fume fever, also known as "Teflon flu," are putting a spotlight on one of the most common causes of the condition, the use of nonstick pans. Over 265 ...
Functional residual capacity (FRC) cannot be measured via spirometry, but it can be measured with a plethysmograph or dilution tests (for example, helium dilution test). Average values for forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1) and forced expiratory flow 25–75% (FEF25–75%), according to a study in the ...
ETFE resins are resistant to ultraviolet light. An artificial weathering test (comparable to 30 years’ exposure) produced no filtering and almost no signs of film deterioration. [4] ETFE systems can control light transmission through the application of plasma coatings, varnishes or printed frit patterns. [5]
A convenient, safe method for generating TFE is the pyrolysis of the sodium salt of pentafluoropropionic acid: [6]. C 2 F 5 CO 2 Na → C 2 F 4 + CO 2 + NaF. The depolymerization reaction – vacuum pyrolysis of PTFE at 650–700 °C (1,200–1,290 °F) in a quartz vessel – is a traditional laboratory synthesis of TFE.
Diagnosis of pneumonia is made clinically, rather than on the basis of a particular test. [13] Evaluation begins with a physical examination by a health provider, which may reveal fever, an increased respiratory rate , low blood pressure (hypotension), a fast heart rate (tachycardia) and changes in the amount of oxygen in the blood.
