Possibility #2 Not all asthmatics wheeze throughout an attack. Some don't wheeze at all. Sometimes lack of wheezing means they are no longer compensating so the lungs are hyper-inflated to the max and wheezing can't happen. Neither lung sounds nor O2 sats are good indicators for asthmatics. Peak- Flow meters are the best way to determine the status.
1 Answer. 0. The upper limit temperature for pressure service is 140 degrees Fahrenheit. ln structural pipe, gravity flow application in stable oils; the upper thermal limit is considered to be in the range of 160F for long term exposure; and up to 180 degrees Fahrenheit for short-term intermittent exposure.
Salmonella bacteria are killed by temperatures above 55Â°C (130Â°F). The rate at which bacteria are destroyed depends on temperature, species, acidity (pH), and humidity (Angelotti et al.). Ten minutes at 65Â°C (150Â°F), or less than two minutes at 70Â°C (160Â°F), are both about as effective as an hour at 60Â°C (140Â°F).
