IPPB

Definition

The application of inspiratory positive pressure
to a spontaneously breathing patient as an
intermittent or short-term therapeutic modality
IPPB

Definition

The delivery of a slow deep sustained
inspiration by a mechanical device providing
controlled positive pressure breath during
inspiration
IPPB

Indications (AARC)

The need to improve lung expansion


Treatment of atelectasis not responsive to other
therapies, (e.g., IS and CPT)
Inability to clear secretions adequately


Limited ventilation
Ineffective cough
IPPB

Indications (AARC)

Short-term nonivasive ventilatory support for
hypercapnic patients

Alternative to intubation and continuous
ventilatory support
IPPB

Indications (AARC)

The need to deliver aerosol medication


When MDI or nebulizer has been unsuccessful
Patients with ventilatory muscle weakness or
fatigue
IPPB

Contraindications (AARC)
Tension pneumothorax

IPPB

Hazards (AARC)





Increase airway resistance (Raw)
Barotrauma, pneumothorax
Nosocomial infection
Hyperventilation (hypocapnia)
Hemoptysis
IPPB

Hazards (AARC)





Hyperoxia when O2 is the gas source
Gastric distention
Secretion impaction (inadequate humidity)
Psychological dependence
Impedance of venous return
IPPB

Hazards (AARC)




Exacerbation of hypoxemia
Hypoventilation
Increased V/Q mismatch
Air trapping, auto peep, overdistended alveoli
IPPB

Potential Outcomes





Improved IC or VC
Increased FEV1 or peak flow
Enhanced cough or secretion clearance
Improved Chest radiograph
Improved breath sounds
IPPB

Potential Outcomes


Improved oxygenation
Favorable patient subjective response

Implementation






Sensitivity of 1 – 2 cm H2O
Initial pressure between 10 – 15 cm H20
Breathing pattern of 6 breaths/min
I:E ration of 1:3 to 1:4
Flow and pressure will need subsequent
adjustment to patient’s needs and goal
IPPB

Implementation

When treating atelectasis





Therapy should be volume-oriented
Tidal volumes (VT) must be measured
VT goals must be set
VT goal of 10 – 15 mL/kg of body weight
Pressure can be increased to reach VT goal if
tolerated by patient
IPPB

Implementation

When treating atelectasis

IPPB is only useful in the treatment of atelectasis
if the volumes delivered exceeds those volumes
achieved by the patient’s spontaneous efforts
IPPB

Discontinuation and Follow-Up





Treatments typically last 15-20 minutes
Repeat patient assessment
Identify untoward effects
Evaluate progress
