    Study Notes

    Incentive Spirometry

    • Incentive Spirometry (IS) is a common therapy to treat hyperinflation.
    • IS devices provide visual clues to patients, displaying numbers that indicate the volume achieved.
    • Indications for IS include upper abdominal surgery, chest surgery, COPD patients undergoing or recovering from surgery, and bedridden patients.
    • Contraindications for IS include patients who cannot be instructed or supervised on the proper use of the device, unconscious patients, or patients who are unable to speak.
    • A hazard of IS is incorrect use or supervision.
    • To calculate the Ideal Body Weight (IBW) for a man at 5’10” weighing 190 lbs, use the formula: ((Height in inches minus 60) x 0.45) + 110
    • To calculate the Inspiratory Capacity (IC) for a patient using IS, use the formula: 45 ml per kg (IBW), figured at age 20.
    • To calculate the IC for a patient older than 20, subtract 100 ml for every 10 years over 20.
    • The basic maneuver of IS is a sustained maximal inspiration (SMI), a slow, deep inhalation from the Functional Residual Capacity (FRC) to the total lung capacity, followed by a 5 to 10 second breath hold.
    • An SMI functionally replicates an Inspiratory Capacity (IC) maneuver followed by a breath hold.
    • During inspiration, the drop in Pleural Pressure (PL) caused by the expanding thorax transmits to the alveoli.
    • This pressure change helps keep alveoli open and re-inflates collapsed alveoli, correcting atelectasis.

    Vibratory PEP Therapy

    • Vibratory Positive Expiratory Pressure (PEP) therapy is performed using a device known as an acapella.
    • The acapella creates positive pressure through expiratory resistance, splints open airways through collateral ventilation.
    • Inspiration fills collapsed alveoli through the Canals of Lambert and the Pores of Kohn, moving secretions to larger airways.
    • The acapella’s vibration provides a percussive effect that loosens mucus from airway walls.
    • Vibration pulsates mucus forward towards larger airways.
    • Vibration also reduces the visco-elasticity of mucus.
    • The acapella's doughnut and rocker movement creates the vibratory effect.
    • The acapella's one-way valve allows patients to inhale and exhale without removing the device from their mouth.
    • The acapella's frequency and resistance dial can be adjusted to suit individual needs.
    • The acapella can be used with a mouthpiece or mask.
    • The acapella can be used with a nebulizer.
    • The acapella DH is for patients capable of maintaining an expiratory flow rate greater than 15 lpm for 3-4 seconds.
    • Cleaning the acapella requires daily cleaning with warm, soapy water, followed by a vinegar solution, and thorough rinsing and drying.

    Flutter Device

    • The Flutter device provides a controlled oscillating positive pressure during exhalation.
    • Oscillations are triggered by variations in exhaled airflow and endobronchial pressure, causing internal vibrations.
    • The Flutter device prevents airway collapse and prolonged hyperpressure.
    • The Flutter device allows for modulation of pressure and airflow oscillation frequency.
    • The Flutter device promotes clearance of small airways.

    EzPAP

    • Positive Airway Pressure (PAP) therapy maintains a positive pressure in the airways throughout the breathing cycle.
    • The therapeutic pressure range for PAP therapy is typically between 5 and 30 cm of water (cm H2O).
    • PAP therapy splints open airways, stabilizes them, and re-inflates collapsed alveoli.
    • EzPAP provides PAP therapy.
    • EzPAP creates positive expiratory pressure through expiratory resistance while exhaling.
    • EzPAP maintains a positive pressure during breath holds.
    • EzPAP provides a positive pressure inspiratory assist during inhalation.
    • EzPAP maintains a variable positive airway pressure throughout breathing.
    • The expiratory resistance provided by EzPAP helps re-inflate the alveoli through collateral ventilation.
    • The inspiratory pressure assist helps hold the airways open.
    • EzPAP benefits post-surgical patients who develop atelectasis, patients unable to perform deep breathing exercises, patients requiring lung expansion therapy who cannot follow instructions, and patients requiring lung expansion with inadequate inspiratory capacity.
    • EzPAP is not CPAP.
    • CPAP maintains constant airway pressure throughout breathing.
    • EzPAP pressure increases during exhalation and decreases during inhalation.
    • EzPAP is a form of PAP therapy that uses a variable, positive airway pressure throughout breathing.
