Bronchial Secretion Retention Clinical Trial
Official title:
Study of Breathing Exercise With Oscillated Inspiratory Loading (OIS) and Oscillated Positive Expiratory Pressure (OPEP) for Airway Secretion Clearance and Lung Function in Intubated Patients, Both With and Without Mechanical Ventilatory Support
The efficacy of breathing exercise with oscillated inspiratory loading and oscillated positive expiratory pressure for airway secretion clearance and lung function in intubated patients, both with and without mechanical ventilation dependence
Effective strategies to increase mucus clearance rate has been suggested to depend on 4
factors.
1. Oscillation at proper frequency.
2. Lung volume and airway opening.
3. Expiratory flow rate or expiratory bias.
4. Humidifying of inspired air.
Multifunctional breathing device, the BreatheMAX, is the only breathing device made in
Thailand. The BreatheMAX device possess many properties or techniques that benefit for
respiratory care particularly 3 in 4 mechanisms for secretion clearance. The unique important
aspect is the simultaneously providing several beneficial effects in one breath which are 1)
Oscillation in the range of ciliary beat frequency 2) Biofeedback of respiratory effort that
could encourage the deeper breathing performance, 3) Humidifier of inspired air, 4) Loaded
breathing for inspiratory muscle training and generate PEP. These 4 functions would be very
useful for increase secretion clearance particularly in more peripheral airway which are the
most difficult to be cleared and be a risk of atelectasis and infection in patients with MV
whose natural secretion clearance mechanisms are compromised, respiratory muscle weakness
weak and low immunity.
Therefore, the combination of inspiratory and expiratory breathing exercise through the
BreatheMAX breathing device may increase or promote more secretion clearance and improve lung
function than expiratory breathing exercise alone in intubated patients, both with and
without mechanical ventilation dependence
