232
Q
A

Reduced FEV1 to FVC ratio

Normal to increased FRC, RV, and/or, TLC

Responsiveness to bronchodilators

233
Q
A

Theophylline

234
Q
A

Increase in physiologic dead space

235
Q
A

Physiologic dead space

236
Q
A

Leukotriene C4

Prostaglandin D2

237
Q
A

Avoid intubation

238
Q
A

Morphine

Aspirin

239
Q
A

Acetylcholine

240
Q
A

Airway resistance

241
Q
A

Decreased elastic recoil and low lung compliance

242
Q
A

Emergence may be prolonged

Q
A

Emphysema

245
Q
A

Hypertrophied mucous glands and chronic inflammation

246
Q
A

Prolong the expiratory time

247
Q

Chylothorax + Lymph

Pleural effusion + Serous fluid

Pyothorax + Pus

Fibrothroax + Organized blood clot

248
Q
A

Flood the surgical field with normal saline

Dobutamine

249
Q
A

Increase expiratory time

250
Q
A

Carbon monoxide inhalation

251
Q
A

1st step + Increase oxygen concentration

2nd step + Apply CPAP 10 cm H2O to nondependent lung

3rd step + Apply PEEP 5-10 cm H2O to dependent lung

4th step + Resume two lung ventilation
