Test 3 Ch.6

Question 1

Ideal Body Weight (IBW) equation for males

Answer 1

106+6 (H in inches- 60) /2.2

Question 2

IBW equation for female

Answer 2

105+5 (H- 60)/ 2.2

Question 3

What is the acceptable initial VTof IBW?

Answer 3

6 to 8 mL/kg

Question 4

What is the acceptance initial RR?

Answer 4

10 to 20 breaths/min

Question 5

For pts which airway obstruction and resistance are high

Answer 5

An initial Vt of 6 to 8 mL/kg for IBW

Question 6

For pts with chronic or acute restrictive disease an initial VT of RR of

Answer 6

8-12 breaths/min

Question 7

For ARDS pts an initial Vt of

Answer 7

4- 6 mL/kg

Question 8

In ARDS an RR of ____-_____ is acceptable

Answer 8

15-25

Question 9

As suggested in restrictive disease lower

Answer 9

VT and higher RR are used in ARDS

Question 10

ARDS protocol (3)

Answer 10

• Low Vt
• high RR
• high PEEP

Question 11

What is Minute Ventilation equation?

Answer 11

VE=VT x F

Question 12

Example of VE: VT is 700, RR is 15

Answer 12

10,500 or 10.5

Question 13

If RR is increased, the pt may have what? and why?

Answer 13

Higher minute ventilation, b/c pt is working hard to breathe

Question 14

The movement of air in &out of the lungs

Answer 14

Minute Ventilation

Question 15

If RR is decreased the pt may have what? and why?

Answer 15

Lower minute ventilation , b/c pt is not working hard enough to breathe

Question 16

How fast the inspired gas will be delivered is called?

Answer 16

Rate of gas flow

Question 17

Shorter I- times result in

Answer 17

higher peak pressures

Question 18

Slow flows may reduce

Answer 18

• peak pressure
• improve gas distribution
• increase mean airway pressure (pMean)
