Medical Forum / Diseases and Disorders / Sinusitis / February 2007Re: Hard nose blowing
Copyright © 2000, the Infectious Diseases Society of America. Abstract Intranasal pressures were measured in adults during nose blowing, sneezing, and coughing and were used for fluid dynamic modeling. Sinus CT scans were performed after instillation of radiopaque contrast medium into the nasopharynx followed by nose blowing, sneezing, and coughing. The mean (±SD) maximal intranasal pressure was 66 (±14) mm Hg during 35 nose blows, 4.6 (±3.8) mm Hg during 13 sneezes, and 6.6 (±3.8) mm Hg during 18 coughing bouts. A single nose blow can propel up to 1 mL of viscous fluid in the middle meatus into the maxillary sinus. Sneezing and coughing do not generate sufficient pressure to propel viscous fluid into the sinus. Contrast medium from the nasopharynx appeared in ges1 sinuses in 4 of 4 subjects after a nose blow but not after sneezing or coughing. --->A single nose blow can propel up to 1 mL of viscous fluid in the middle meatus into the maxillary sinus.

Thick , sticky with high resistance to flow. Gluey goo which may or may not contain whatever is in the goo when it enters. If the goo is totally without any harmful pathogens , then no problem. But it's probably better to rinse out the goo before we try to shotgun the goo , in my opinion. All sinus goo is not created equal, and goo characterization research should be a rich area of study. Will someone in the medical community PLEASE drop some SYTO 9 nucleic acid stain and Propidium iodide on the goo? Apply some of these probes used to study waste water on sinus goo and you will be supprised what you find. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=106222 http://probes.invitrogen.com/lit/bioprobes25/part06.html On 2/20/07 6:29 AM, in article f9ed3649b7a0b92455cc4726e3289a7c@localhost.talkaboutsupport.com, "loxaluck" > is it good or bad to propel viscous fluid into the maxillary sinus? No, its not bad, its VERY bad. is it better than to leave the viscous fluid in the middle meatus ? people blow their nose all the time... >is it better than to leave the viscous fluid in the > middle meatus ? > >people blow their nose all the time... ..And lots of people develop sinus problems too. ..My past experiences has confirmed to me that nose blowing can make a sinus condition worse. Thus, I would say: don't do it. ...But if you don't want to take that advice and wish to continue blowing your nose, then go for it. ...Jon
