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.
What is the melting temperature of polyethylene melting point?   Low-density polyethylene (LDPE), used e.g. for transparent zipbags or covers for the 50-CD round boxes, melts at approximately 105 - 110 degrees Celsius. Can be used conâ¦stantly at about 80 degrees, and withstands 95 degrees Celsius for a short time.   High-density polyethylene (HDPE), used for supermarket plastic bags, motor oil and laundry detergent bottles, melts at a slightly higher temperature, 130-137 degrees Celsius.
