high doses of CS are used initially for
|
moderate to severe asthma exacerbations
|
|
in the setting of acute pulmonary edema...
|
100% O2 must be provided often under positive pressure the patient is maintained in the upright position with legs dangling if possible to assist fluid redistribution from the lungs
|
|
IV loop dieuretics are used in acute pulmonary edema because
|
not only diurese but cause increased venous capacitance with the usual starting dose of furosemide being 20-80mg IV...sublingual NG also causes redistribution and can be administered
|

patients requiring nitrodrip because of high BP require what
|
art line
|
|
may be of limited benefit in patients presenting with acute pulmonary edema

|
|
dyspnea occurs in 75% of pregnant women by when
|
30th week 2/2 higher diaphragm, blood redistribution and progesterone causing increased CO2 sensitivity...the physiologic dyspnea of pregnany rarely increases in severity in the final weeks
|
|
life threatening causes of dyspnea in the pregnant patient are
|
preeclampsia and PE
|
|
which dyspnea patients need to be admitted
|
patients requiring supplemental O2 to maintain Oxygenation and those with distress...also recommended in in someone with unstable angina having dyspnea even if they respond to therapy in the ED
|
|
normal A-a gradient
|
2-10 but this increases with age and may be as high as 30 in elderly
|
|
A-a gradient calculated by
|
(713)FiO2- PaCO2/0.8
|
|
causes of an A-a gradient
|
1. V/Q Mismatch (ex: PNA, CHF, ARDS, atelectasis, etc)
2. Shunt (ex: PFO, ASD, PE, pulmonary AVMs) 3. Alveolar Hypoventilation (ex: interstitial lung dz, environmental lung dz, PCP PNA) |
|
best CXR for dyspnic
|
PA and Lateral however a portable AP is often necessary at bedside
|
|
CXR worrisome for PE
|
a normal one in the setting of Hypoxemia
