A Novel Unidirectional Face Mask During NPPV in COPD Patients

This study has been withdrawn prior to enrollment.
(Inability to enrole subjucts.)

Yandong Jiang, Massachusetts General Hospital Identifier:
First received: August 27, 2009
Last updated: January 13, 2017
Last verified: January 2017
The purpose of this study is to determine the feasibility, safety and efficacy of a unidirectional breathing mask (breathe in through the nose and out through the mouth or breathe in through the mouth and out through the nose) in COPD patients with breathing difficulties requiring noninvasive positive pressure ventilation (NPPV).

Condition Intervention
Chronic Obstructive Pulmonary Disease
Device: A unidirectional face mask (Modified 'Respironics PerformaTrak' Mask)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Use of a Novel Unidirectional Face Mask During Noninvasive Positive Pressure Ventilation (NPPV) in Chronic Obstructive Pulmonary Disease (COPD) Patients

Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • Reduction in anatomical dead space and improvement in ventilatory efficiency [ Time Frame: 30 minutes ]

Secondary Outcome Measures:
  • Improvement of ventilation rate, tidal volume, end tidal CO2, arterial pH, PaCO2, and PaO2, SpO2, pulse rate, blood pressure and patient rating of comfort of each ventilatory pattern. [ Time Frame: 30 minutes ]

Enrollment: 0
Study Start Date: March 2011
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: COPD
Thirty adult (> 18 years of age) patients in acute hypercapnic respiratory failure resulting from COPD and requiring Noninvasive Positive Pressure Ventilation (NPPV)
Device: A unidirectional face mask (Modified 'Respironics PerformaTrak' Mask)
The regular face mask will be replaced with the study mask and patients will receive NPPV via the study mask for 30 min. The study mask insures a unidirectional breathing pattern, in through the nose and out through the mouth or in through the mouth and out through the nose. The sequence of these two breathing patterns with opposite flow direction will be chosen randomly. Each will be applied for 30 min with data collected during and at the end of the period.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Acute hypercapnic respiratory failure as a result of an acute exacerbation of COPD defined as PaCO2 > 50 mmHg, with or without hypoxia, and a respiratory rate of greater than 25/min with the use of accessory muscles of respiration or abdominal paradox;
  2. Requiring NPPV as assessed by the managing care team.

Exclusion Criteria:

  1. Patients with facial deformity, heavy beard or moustache which prevents a good seal between the mask and the face;
  2. Patients who have claustrophobia and cannot wear the mask;
  3. Patients who are hemodynamically unstable;
  4. Patients who are disoriented and unable to cooperate with the study procedure;
  5. DNI or DNR status or patients in whom intubation is contraindicated;
  6. Patients who are currently intubated;
  7. Patients who recently (< 6months) had an MI or stroke;
  8. Pregnant woman; There will be no exclusion based on gender, race or ethnicity.
