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.
Concrete should not be exposed to temperatures 20ÂºF above the minimum placement temperatures. ACI 306R-88 Chpt 7.4 11. The temperature of the concrete and the ambient air and recorded at least twice in 24 hr period. Temperatures should be taken at more than one location, on edges and corners. 12. mix. APWA 03 30 04 2.5 E1 4. Non chloride admixtures may be used but placement, curing and protection requirements must be observed. APWA 03 30 10 3.4 A2 5. Temperature of concrete as placed should be as close to the minimum recommended value as possible (55Âº F) ACI 306R-88 Chpt 3.1 6.
