peep - interndoc

[ArchivalUser]

which one hemodynamic parameter that you would like to monitor:

a.sytolic BP
b. urine output
c. cardiac output
d. systemic vascular resistance
e.central venous pressure

[ArchivalUser]

peep you will like to monitor cardiac output

but later one urinary output peep cause siadh

cardic output depends upon heart rate and stroke volume and stroke volume depend upon venous return venousreturn depend upon blod pressure so monitor systolic bllod pressure

blod pressure also depend upon cardiac output as well as systemic vascular resistance so mnitor that also

cvp also depend upon co and venous return


so basically if you monitor cardic output you monitor everything so iwill monitor cardiac output

[ArchivalUser]

for a moniter which is easier Systolic BP or CO ?? I guess Bp is easeier as well s informative ..coz if it decrease then the perssure in chest is high

[ArchivalUser]

we need cardiac output because peep is a procedure wher you give mechanichal ventilatation with end expiratory pressure and if you give more peep and this can cause obstructive shock meaning blood from lung cannot reach left chambers and cardiac output will decrease , so byy seeing cardiacoutput we will know whether pressure of peep is ok or not and we can adjust it.

well bp == co x svr

but bp can be falsely elevated or less due to vasoconstriction but forward flow may not be there

but if cardic output is ok means the blood must have come out of left chamber towards the body

so cardiac output is more direct and reliable

but iamnot sure of my explanation but it suits me for the timebeing

[ArchivalUser]

actually may 20 can explain it, i suppose

I thought we monitor Co in PEEP for the risk of pneumothorax.

[ArchivalUser]

We have to measure CO because PEEP causes decreased venous return to left heart because of increased pleural pressure and decreased RV ejection due to increased transthoracic pressure(alveolar minus pleural). This causes a decrease in LV output, especially in patients with compromised LV filling.
In addition to this, PEEP when in high amounts can cause barotrauma and tension pneumothorax, which increases the pressure on the heart , causes hypoxia and impairs venous return. Another reason to watch the CO.

[ArchivalUser]

CO is to monitored by PEEP.

whats the answer Interoc?
