obstructive may be due to?

↓ pulmonary compliance
alveolar ventilation perfusion mismatch
restrictive of alveolar distend
peripheral airway stenosis
2/15

which is the cause of respiratory failure?

anemia
pneumonia
metheoglobinemia
cyanide intoxication
3/15

oxygen therapy for type II respiratory failure is?

low concentration in nasal tube and slowly flow
high concentration in nasal tube and slowly flow
low concentration in nasal tube and quickly flow
high concentration in nasal tube and quickly flow
4/15

respiratory failure always refer to?

severe dysfunction of internal respiration
severe dysfunction of external respiration
dysfunction of elimination of CO2
disorder of hemoglobin for transport gases
5/15

chronic obstructive pulmonary diseases may lead to?

inspiratory dyspnea
hyperventilation of alveolar
expiratory dyspnea
dead spece like ventilation
6/15

ventilation disorder lead to?

PaO2↓, no altered for PaCO2
PaO2↓, PaCO2↓
PaO2↓, PaCO2↑
no altered for PaO2,PaCO2↑
7/15

the most common cause of chronic respiratory failure is?

infection of upper respiratory tract
chronic obstructive pulmonary disease
embolism of pulmonary arery
overdoes of sedatives or anestetic agents
8/15

pulmonary hypertension always secondly to chronic obstructive pulmonary disease because?

pulmonary arteriole constriction
↑ of cardiac output
PaCO2 ↓
formed of microthrombus
↑ of blood volume
9/15

dead space-like ventilation refer to?

hypoventilation in some alveolar
↓ ( V/Q) in part alveolar
right-to-left shunt
↑ (V/Q) in part alveolar
10/15

thype II respiratory failure is diagnosed by?

PaO2 < 50 mmHg(6.67 kPa),PaCO2 > 60mmHg(8 kPa)
PaO2 < 60 mmHg(8 kPa),PaCO2 > 50mmHg(6.67 kPa)
PaO2 < 50 mmHg(6.67 kPa),PaCO2 > 40mmHg(5.33
kPa)
PaO2 < 70 mmHg(8 kPa),PaCO2 > 40mmHg(5.33 kPa)
11/15

which of following may result in functional shunt?

embolism of pulmonary artery
↓ pressure of pulmonary artery
pulmonary edema
contraction of pulmonary arteriole
12/15

sedative agents overdosed lead to depressed of respiratory center and blood gases may altered?

PaO2↓, no altered for PaCO2
PaO2↓, PaCO2↓
PaO2↓, PaCO2↑
no altered for PaO2,PaCO2↑
13/15

the difference between functional shunt and true shunt is?

PaO2 ↓
PaCO2 is normal
PaO2 may not ↓
difficult to improve PaO2 by ure oxygen inspired
no help to improve PaO2 and PaCO2 by the therapy
of ↑ ventilation
14/15

which disease may lead to restrictive hypoventilation?

paralysis of glottis
poliomyelitis
tumor in trachea
chronic obstructive pulmonary disease
edema of glottis
15/15

pulmonary consolidation result in?

functional shunt
true shunt
(V/Q) ↑
wasted ventilation
