RS failure

Question 1

Type 4 RS failure

Answer 1

Under perfusion of RS muscle
due to shock : Pulmonary edema
decrease supply of RS muscle

Mx : ET tube with IPPV
shock : Impella / Inotrops

Question 2

Type 3 RS failure

Answer 2

Peri operative atelectasis
-GA : decrease FRC - collapse of basal lung segment
-O2 saturation less
Inadequate Analgesia
- pain cause hyperventilation
- CO2 wash out lead respiratory alkalosis

Mx : O2 supplements
Chest Physiotherapy
Incentive spirometry

Question 3

Type 2 RS failure

Answer 3

decrease pO2 , increase pCO2
DIAPHRAGMATIC PARALYSIS or
HYPOVENTILATION

Mx : Tight fitting face mask
SpO2 > 90%
DIAPHRAGMATIC PARALYSIS : ET tube with IPPV

Question 4

Type 1 RS failure

Answer 4

decrease pO2 , decrease/normal pCO2
HYPERVENTILATION

Mx : low volume ventilation
Prone position
Neuromuscular blockage
