Impact of Face Masks on 6-Minute Walk Test in Healthy Volunteers.

Our objective was to establish the impact of wearing a face mask on the outcome of six-minute walk test in healthy volunteers. In a study of 20 healthy volunteers who each completed two 6MWTs, one with a mask and one without, there was no difference in distance walked. However, there was a significant difference in perception of dyspnea between the two groups.

Living with pulmonary artery hypertension: patients' experiences.

BACKGROUND: Research on the outcomes of medical therapy in persons with pulmonary artery hypertension (PAH) has increased as new therapeutic options have emerged. Little investigation has been done on the impact of living with PAH despite inferences that quality of life (QOL) improves. PURPOSE: The purpose of this qualitative study was to describe patient experiences of living with PAH and identify factors that may have an impact on QOL. PARTICIPANTS: Participants (n = 11; 8 women, 3 men) were selected from among 42 adult patients, 40 to 72 years of age, followed in an outpatient setting at a tertiary care hospital. Multiple types of treatment modalities were represented including calcium channel blockers, endothelin-receptor antagonists, prostacyclin analog, and lung transplantation. METHODS: Semistructured interviews allowed participants to describe experiences living with PAH. Interviews were recorded on audiotape and transcribed verbatim. Analysis was conducted in accordance with Colaizzi's 7-step process for analysis of phenomenologic data. RESULTS: Two overarching themes emerged indicating that participants experience uncertainty associated with a variety of aspects of this illness but also learn to cope with this uncertainty and move on with their lives. IMPLICATIONS: Assisting patients to cope with the uncertainty associated with this chronic health problem is essential if patients are to successfully adjust to the demands of the illness and its treatment. Attention to the findings of this study should guide health care professionals in their efforts to improve QOL in this patient population.

The end-of-life experience for a cohort of patients with pulmonary arterial hypertension.

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a progressive and ultimately fatal disease of the pulmonary circulation. There has never been an investigation of the end-of-life symptoms in patients with PAH. In this investigation, we surveyed surrogates of recent decedents with PAH. We evaluate their responses to better understand the end-of-life experience of patients with PAH. METHODS: The survey instrument includes demographic information and the Edmonton Symptoms Assessment Scale. Accredo Therapeutics mailed the survey to surrogates of recent decedents with PAH, and responses were anonymously returned to investigators at Virginia Commonwealth University and used in our descriptive analysis. RESULTS: Of 100 surveys distributed over 24 months (February 2009 to February 2011), we obtained 36 responses (response rate 36%). We found that most patient deaths (90%) were related to PAH, that the majority of patients died in the hospital (67%), with the majority of in-hospital deaths (83%) occurring in intensive care. Palliative care was infrequently involved in patients' care, and many surrogates were unaware of palliative care and hospice services available to the decedents. Patients died with a high symptom burden, especially dyspnea. CONCLUSION: In this cohort, patients with PAH usually died from their disease, often in the hospital setting with a high symptom burden. Further study will be needed to confirm the findings from this study and to better understand the forces leading to the trends uncovered in this investigation.
