Pulmonary embolism (PE) can occur without deep vein thrombosis (DVT). Pulmonary embolism (PE) and deep vein thrombosis (DVT) usually occur as part of the same process. While most DVTs happen in the legs, they can also occur in other parts of the body such as the arms. If a DVT is suspected, it is important to have a quick diagnosis and treatment to prevent PE.

Propane is a hydrocarbon (C 3 H 8) and is sometimes referred to as liquefied petroleum gas, LP-Gas or LPG. Propane is produced from both natural gas processing and crude oil refining. It is nontoxic, colorless and virtually odorless. As with natural gas, an identifying odor is added so the gas can be readily detected.
