PAWP readings - page 2
I'm looking for information about standards ralated to manual wedging of PA caths and frequency of such. We are having a "war in our facility about frequency of wedging in absence of direct MD... Read More
Mar 31, '02On the vented vs spontaneously breathing patient. If your vented patient is overbreathing the vent then it is considered a spontaneous breath and you would read the PAWP at the peak not at the valley. Whereas ventilator breaths are read in the valley. I just learned this last Fall from Dr. Tom Ahrens. So unless your patient is paralyzed then be sure to watch whta type of breath your patient is taking is it spontaneous (their own initiated breath) or ventilator forced breath....Hope this helps. As far as how often to wedge. I learned every 4 hours. Then learned whenever you thought the patient needed it(change in condition, BP, HR, etc.). I would suggest talking to the surgeons or cardiologists who most often use Swans how often they would like PAW readings.....Then take it to your manager to be looked at when and if your policies are reviewed..........Just my .02 worth
Apr 2, '02A good site (free) to learn all about PA's and such is
Just a tidbit. I've looked into the site and it seems pretty decent.
Sep 10, '02Wow, I am surprised to learn of the frequency of wedging at other places! Where I work we wedge q2h and even more often if needed. However, our patients generally do not have a Swan for more than two or three days. We do have a very high acuity of patients and alot of times the PA diastolic does not correlate with the wedge pressure. We generally treat off the wedge.
