Unit 1: Pulmonary Edema Flashcards
Pulmonary edema occurs from diseases that result in…
FVO!
Causes of Pulmonary Edema (7)
- HF
- RF
- ARDs
- High altitudes (vasoconstriction leading to capillary leakage)
- Brain trauma
- Rapidly expanding lung
- Laboring AFAB (due to FVO)
We said pulmonary edema could result from a “rapidly expanding lung,” but when might we see this?
Pt with a pneumothorax that gets a chest tube, which rapidly expands the lungs
Removal of fluid from the pleural space quickly
What patient population is most at risk for developing Pulmonary edema? Why?
Older adults; Higher incidence of HF
As the amount of blood ejected from the left ventricle diminishes, the hydrostatic pressure builds in the pulmonary venous system and results in fluid-filled alveoli and pulmonary congestion..
What mental status changes would we see with pulmonary edema? Why? (4)
- Confusion (disorientation)
- Restlessness
- Anxiety
- Lethargy
Decreased O2 to the brain
What early S/S in older adults might we suspect for pulmonary edema?
Confusion!
Gramps be talkin’ none sense again
Objective S/S of pulmonary edema (7)
- Crackles in lung bases
- Dyspnea (at rest)
- Cough (irritating + persistent)
- Pink, frothy sputum
- Tachycardia leading to dysrhythmias
- Altered BP
- Reduced U/O
Late S/S: diaphoresis + cyanosis
In what situations would hypotension be present along with pulmonary edema? What else might we see?
Decreased cardiac output (Ex. caused by an acute MI or left-sided HF)
Decreased Urine output
What’s suuuper important to document about the lung sounds heard r/t pulmonary edema?
The precise location of the crackles!
B/c the level of fluid progresses from the bases to high levels in the lungs as the condition worsens
What’s the simplest nursing intervention we should perform if we suspect pulmonary edema?
Reassurance!
“Chill tf out brother”
Nursing Interventions r/t to Pulmonary edema:
- Raise HOB
- Oxygen
- SpO2 + VS
- Meds (or IV access to admin them)
Medical Mx of pulmonary edema aims to reduce ______ and _______ on the heart.
Reduce preload (pulmonary venous return) and afterload (systemic vascular resistance) on the heart
What medications do we use for pulmonary edema? (3)
Indicate whether the med reduces preload, afterload, or both.
- Diuretics (preload)
- Nitroglycerin (preload + afterload)
- Morphine (afterload + maybe preload)
What medication would we use if we had pulmonary edema aaand hypotension?
Ionotropic support (increase the squeeze/contractility of the heart) = positive inotropes
Ex. dobutamine
If a renal failure patient develops pulmonary edema, what do?
Ultrafiltration
*she said HF pt’s in her lecture…. ?
