fundamentals of resp care 1

Question 1

causes of atelectasis

Answer 1

• low inspiratory tidal volume
• post op- pain
• upper abdominal surgery or thoracic surgery
• use of narcotics

Question 2

effects of atelectasis

Answer 2

• decreased lung compliance

- -decreased residual volume

Question 3

clinical signs of atelectasis

Answer 3

• starts to develop in first 24 hours after surgery
• worse over next 24 hours
• increased temp & WOB (work of breathing)
• tachycardia and tachypnea

Question 4

outcomes of incentive spirometry use

Answer 4

• absence of signs or improvement of lung collapse
• decrease RR
• normal HR
• normal CXR
• improvement of PaO2 and AaDO2

Question 5

difference between flow and volume incentive spirometer

Answer 5

flow- measures flow rate of inspired gas and displays it as volume, indirect measurement
volume- directly measures the inspired volume of each breath
