  74. What characteristics are contained in a Flow-oriented Incentive Spirometry (IS or SMI) device?
    • -The patient�s inspiratory flow rate causes a float to rise in a canister
    • -The patient should maintain an inspiratory flow that slowly elevates the ball
    • -Rapid inspiration will cause the float to rise too quickly but will not maintain it in a suspended position
    • -Slow inspirations do not generate sufficient flow to raise the float
  75. What characteristics are contained in a Volume-oriented Incentive Spirometry (IS or SMI) device?
    • -The patient inspires until a preset volume of gas is inhaled
    • -Indicators are used to motivate patients and indicate when desired volume is achieved
    • -Most systems are designed to require a sustained inspiration before the achieved volume indicator is activated.
