Presentation Transcript

  1. Intermittent Positive Pressure Breathing (IPPB) RET 2275L Respiratory Therapy Theory Lab 2 Module 3.0

  2. IPPB • Definition • The application of inspiratory positive pressure to a spontaneously breathing patient as an intermittent or short-term therapeutic modality

  3. IPPB • Definition • The delivery of a slow deep sustained inspiration by a mechanical device providing controlled positive pressure breath during inspiration

  4. 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

  5. IPPB • Indications (AARC) • Short-term nonivasive ventilatory support for hypercapnic patients • Alternative to intubation and continuous ventilatory support

  6. IPPB • Indications (AARC) • The need to deliver aerosol medication • When MDI or nebulizer has been unsuccessful • Patients with ventilatory muscle weakness or fatigue

  7. IPPB • Contraindications (AARC) • Tension pneumothorax ________________________________________ • ICP > 15 mm Hg • Hemodynamic instability • Recent facial, oral or skull surgery

  8. IPPB • Contraindications (AARC) • Tracheoesophageal fistula • Recent esophageal surgery • Active hemoptysis • Nausea • Air swallowing

  9. IPPB • Contraindications (AARC) • Active, untreated TB • Radiographic evidence of bleb • Singulus (hiccups)

  10. IPPB • Hazards (AARC) • Increase airway resistance (Raw) • Barotrauma, pneumothorax • Nosocomial infection • Hyperventilation (hypocapnia) • Hemoptysis

  11. IPPB • Hazards (AARC) • Hyperoxia when O2 is the gas source • Gastric distention • Secretion impaction (inadequate humidity) • Psychological dependence • Impedance of venous return

  12. IPPB • Hazards (AARC) • Exacerbation of hypoxemia • Hypoventilation • Increased V/Q mismatch • Air trapping, auto peep, overdistended alveoli

  13. IPPB • Potential Outcomes • Improved IC or VC • Increased FEV1 or peak flow • Enhanced cough or secretion clearance • Improved Chest radiograph • Improved breath sounds

  14. IPPB • Potential Outcomes • Improved oxygenation • Favorable patient subjective response

  15. IPPB • Baseline Assessment • Vital signs • Patient’s appearance and sensorium • Breathing pattern • Breath sounds

  16. IPPB • Implementation • Infection control • Equipment preparation • Pressure check machine/circuit • Patient orientation • Why MD ordered therapy • What treatment does • How it feels • Expected results

  17. IPPB • Implementation • Application • Mouthpiece / nose clip (initially) • Mouthseal • Mask • Trach adaptor

  18. IPPB • Implementation • Machine settings • 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

  19. 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

  20. 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

  21. IPPB • Discontinuation and Follow-Up • Treatments typically last 15-20 minutes • Repeat patient assessment • Identify untoward effects • Evaluate progress • Document
