    Study Notes

    Incentive Spirometry

    • Sustained maximal inspiration (SMI) for 5-10 seconds to reach inspiratory capacity
    • Target is 30% of inspiratory capacity (IC)
    • IC calculation: IBW (kg) x 45
      • Example: 75.45 kg individual = 75.45 x 45 = 3,395.45 ml
      • Target IS: 3,395.45 x 0.30 = 1,018 ml
    • Requires patient cooperation and ability to use mouthpiece effectively

    EzPAP

    • First-line alternative to incentive spirometry
    • Can be administered to unconscious patients
    • May use a mouthpiece or a mask
    • Therapeutic range of 8-12 cmH2O
    • Can be coupled with a nebulizer
    • Replaces older IPPB therapy
    • Uses "Coanda" effect to amplify flow from the flowmeter

    Vibratory Therapy

    • Used to loosen and remove secretions via percussive effect
    • Devices:
      • Acapella: Variable resistance
      • Flutter Valve
      • Aerobika
      • Metaneb
      • Acapella: Can use a mouthpiece or mask, requires patient cooperation, can be tied to a nebulizer

    PAP - Positive Airway Pressure

    • Objectives:
      • Prevent or improve atelectasis:
        • Recruits collapsed alveoli
        • Improves gas distribution
        • Reduces work of breathing
      • Increase functional residual capacity (FRC) and improve oxygenation
      • Open up the airways

    Incentive Spirometry

    • Sustained, maximal inspiration (SMI) with a 5-10 second breath hold.
    • Targets 30% of inspiratory capacity (IC).
    • IC calculated: IBW (kg) x 45.
    • Example: 75.45 kg individual IC = 3,395.45 ml.
    • Target IS: IC x 30%.
    • Requires patient cooperation to attempt the therapy.
    • Patient must be able to effectively use a mouthpiece.

    EzPAP

    • First-line alternative if a patient cannot perform incentive spirometry (IS).
    • Can be effectively administered on an unconscious patient.
    • Can be used with a mouthpiece or mask.
    • Best therapeutic range 8 to 12 cmH2O (some sources say 20 or 30 cmH2O).
    • Can be coupled with a nebulizer.
    • Replaces older IPPB therapy.
    • Uses the "Coanda" effect to amplify flow from the flowmeter.

    Vibratory Therapy

    • Used to loosen and remove secretions by using a percussive effect to disengage mucus.
    • Devices include: Acapella, Flutter Valve, Aerobika, Metaneb, and Acapella.
    • Acapella can use a mouthpiece or mask, has variable resistance, and can be tied to a nebulizer.

    PAP Therapy Objectives

    • Prevent and improve atelectasis:
      • Recruits collapsed alveoli.
      • Improves gas distribution.
      • Improves work of breathing (WOB).
    • Increase functional residual capacity (FRC) to improve oxygenation.
    • Open up the airways.

    Incentive Spirometry

    • A sustained, maximal inspiration (SMI) that involves a 5 to 10 second breath hold and inspiratory effort to reach the patient's inspiratory capacity
    • Target is usually 30% of the patient's inspiratory capacity (IC)
    • IC is calculated by multiplying the patient's ideal body weight (IBW) in kilograms by 45
    • The patient must be cooperative and be able to utilize a mouthpiece effectively

    EzPAP

    • First line alternative if a patient cannot perform incentive spirometry (IS)
    • May be effectively administered on an unconscious patient
    • A mouthpiece or mask can be used
    • Best therapeutic range is 8 to 12 cmH2O (some sources suggest 20 cmH2O or even 30 cmH2O)
    • May be coupled with a nebulizer
    • Replaces older IPPB therapy
    • Utilizes the "Coanda" effect to amplify the flow from the flowmeter approximately 4 times

    Vibratory Therapy

    • Used to loosen and remove secretions through a percussive effect that disengages mucus from airway walls
    • Devices include:
      • Acapella: variable resistance
      • Flutter Valve: used for chest physiotherapy techniques
      • Aerobika: used for chest physiotherapy techniques
      • Metaneb: used for chest physiotherapy techniques
      • Acapella: can use mouthpiece or mask, variable resistance, requires patient cooperation, and can be coupled with a nebulizer

    PAP Therapy - Objectives

    • Prevents or improves atelectasis by:
      • Recruiting collapsed alveoli
      • Improving gas distribution
      • Reducing work of breathing (WOB)
    • Increases functional residual capacity (FRC) to improve oxygenation
    • Opens up airways
