Breathing is an act that most people do not consciously evoke unless there is a presence of illness that affects the respiratory system. Adults generally take in 12 to 15 breaths per minute without even a thought about the body’s mechanics that allow for proper oxygenation and ventilation. However, for those with pulmonary compromise, breathing becomes a very conscious, deliberate, and sometimes laborious act. The purpose of this paper is to demonstrate the use of the explicitation method by Petitmengin by interviewing a subject to elicit the lived experience of breathing by an individual with end-stage cystic fibrosis (CF). To apply the interview method, the following phenomenological question guided the interviewer’s approach: What is the lived experience of breathing upon waking for an individual with CF? This paper includes a transcription of the interview followed by a self-critique, textual analysis, and discussion of the implications to health care.

OBJECTIVE: To investigate the short term effects of high frequency chest compression (HFCC) on several indices of respiratory system mechanics in normal subjects and patients with cystic fibrosis (CF).DESIGN: Comparative physiological approach. Subjects were blinded to 10 randomized HFCC settings (5, 10, 15, 20 and 25 Hz) with each applied at the lowest and at the highest background vest pressure.SETTING: Pulmonary function and lung mechanics laboratory, University of Alberta.PARTICIPANTS: Ten normal male volunteers (24.2±3.8 years) and 11 clinically stable CF patients (23.4±6.7 years). Normal subjects were nonsmokers who had normal lung function. The CF patients had a wide range of airway obstruction.INTERVENTIONS: HFCC was supplied by oscillating a pneumatic vest that covered the entire torso. Balloon tipped catheters were used to measure esophageal (Pes) and external chest wall (Pew) pressures. Changes in end-expiratory lung volume (EELV) during HFCC were measured from a spirogram and were compared with baseline functional residual capacity (FRC). The HFCC induced air movement al the mouth, oscillated tidal volume (Vosc), was measured by reverse plethysmography.RESULTS: Both normals and CF patients had similar changes in Pes and EELV. At the highest background vest pressure and at the higher oscillation frequencies, EELV decreased approximately 30% from the no-HFCC baseline FRC. Vosc decreased with increasing oscillation frequency but normals had higher Vosc than CF patients at each frequency. Conversion of Vose to flow (V˙osc) revealed that the highest Vosc occurred between 10 and 15 Hz for both normals and CF patients. Also, Vosc was dependent on the overall airway function. Low forced expired volume in 1 s resulted in low Vosc, especially when Vosc was measured during spontaneous expiration.CONCLUSIONS: CF patients with moderate or severe airway obstruction may gain maximal benefit from HFCC therapy when low vest pressure is used at an oscillation frequency of 10 to 15 Hz. The low vest pressure minimizes the decrease in EELV and 10 to 15 Hz maximizes Vosc.
