1
Q

Cardiogenic pulmonary edema

A
  • CHF–> MCC
  • Cardiomegaly on XR
  • Responds to O2
2
Q

Noncardiogenic pulmonary edema

A
  • Damage to the alveoli or capillary without elevation of the pulmonary capillary wedge pressure.
  • Ex: ARDS and PE
  • Does not respond to O2
3
Q

Neurogenic NCPE

A

Subarachnoid hemorrhage, head trauma

4
Q

Re-perfusion NCPE

A

Lung injury, occurs after surgery

5
Q

Re-expansion NCPE

A

S/p rapid expansion of collapsed lung in pneumothorax

6
Q

Opioid overdose NCPE

A

Heroin overdose, tx: Naloxone (Narcan)

7
Q

Salicylate NCPE

A
  • Salicylate toxicity/poisoning, ASA OD

- Tx: Sodium bicarb

8
Q

Inhalants NCPE

A
  • Cleaning products, chlorine gas, ammonia
9
Q

Virchows triad for PE

A
  • Vascular intimal trauma: damage to inner lining of vessel
  • Ex. HTN, smoking, ICDA, trauma, surgery
  • Venous stasis: blood not in motion - stagnation thrombi
  • Ex. Long flights, a.fib, pregnancy, obesity, varicose veins
  • Hypercoagulable state: thick sludgy blood, sticks and forms clots
  • Ex. BC pills, malignancy
10
Q

Manifestations for PE

A

dyspnea (MC sx), tachypnea (MC sign), tachycardia (MC ekg finding)

11
Q

MC diagnostic test for PE

A

CTA

12
Q

Gold standard diagnostic test for PE

A

Pulmonary angiography

13
Q

WHO classification for pulmonary HTN grade 1

A
  • Pulmonary arterial hypertension (PAH)

- idiopathic, familial, HIV, women, poor prognosis

14
Q

WHO classification for pulmonary HTN grade 2

A

Left heart disease (MC)

15
Q

WHO classification for pulmonary HTN grade 3

A

Lung disease and or chronic hypoxemia

16
Q

WHO classification for pulmonary HTN grade 4

A

Chronic thromboembolic disease

ex. Recurrent PE

17
Q

WHO classification for pulmonary HTN grade 5

A

Miscellaneous

18
Q

Pathophysiology of pulmonary HTN

A
  • Passive resistance in pulmonary venous system
  • Hyperkinetic
  • Obstruction
  • Pulmonary vasoconstriction
19
Q

ARD pathology

A
  • neutrophil activation in the systemic and pulmonary circulation.
  • Occurs secondary to another inflammatory process.
  • Massive intrapulmonary shunting of blood
20
Q

MCC of ARDS

A

Sepsis

21
Q

ABG testing in ARDS you’ll find

A

All ABGs are possible to see

22

A

PCWP low <18

23
Q

ARD management you want to avoid

A

fluid overload and permanent damage ie honeycombing
