Corticosteroids are also used supportively to prevent nausea, often in combination with 5-HT3 antagonists (e.g. ondansetron). Typical undesired effects of glucocorticoids present quite uniformly as drug-induced Cushing's syndrome.
Common causes. A gas explosion occurs when the gas/air mixture reaches a critical value, then any spark, flame or heat source can ignite the mixture. The explosion is caused when the rapidly expanding, burning gas is confined and builds up pressure. As the pressure builds, something has to give, and in a home gas explosion it is usually the windows.
If the noise happens only when your furnace comes on and it takes several seconds or even minutes before hot air comes, the furnace burners may be dirty. Dirt on the furnace burners allows gas to accumulate in the furnace before the gas ignites. This delayed ignition from that big gas buildup causes the loud bang. Itâs like a mini-explosion. Please donât ignore this noise as delayed ignition can crack your furnaceâs heat exchanger. And once thatâs cracked, youâll need a new furnace. Have a professional clean the furnace burner if this is the cause of the noise. If you hear the noise a few feet away from the furnace, then the problem is likely with the air ducts. When your furnaceâs blower starts, itâs both sucking in air from your home and blowing it out through supply ducts.
