ARDS WKST

type of pulm edema seen in ARDS

is non-cardiogenic cause by heart failure

in ards, lung compliance inc/dec

dec compliance causes lungs to become more

why lung compliance changes in ARDS (3)

hypoxemia that responds poorly to supplemental oxygen administration is termed:

treatment for ARDS

PCWP in ARDS will most likely be

static compliance provides info about the

static comp values are often as low as

increase ppl, static compliance =

relationship btwn ppl pressure and static lung comp is

ratio of carbon dioxide to oxygen consumed is termed

what makes RQ high

what makes RQ low

what RQ is more ideal for ARDS pt?

most common etiologic factor associated with the development of ARDS

ppl pressure should be monitored in an attempt to keep the value less than

ppl pressure less than 30 helps by reducing the risk of

mech ventilation strategies in ards includes

goal of this strategy is to dec high airway pressures, reduce over distension of the lungs, and dec rish of barotrauma

used in conjuction w/ pressure control to allow more time for inspiration thereby increasin alveolar contact time w/ oxygen

decrease high airway pressures, reduce overdistension of the lungs, and decrease risk of barotrauma while maintaining adequate min vent

level of peep at which oxygenation improves w/out compromising cardiac output

level of peep in which a pa02 of >60 is achieved on an fi02 of <60

measure of the partial pressure of oxygen in mixed venous blood and is an indication of oxygen consumption by the body is termed as

normal values of pv02

chest radiograph findings of a pt w/ ARDS (2)

use of small vt or inverse i:e ratio to keep the ppl pressure less than 30 may result in hypercapnea but is acceptable to have hypercapnea as long as the pt's pH is greater than 7.20
