A Mixed Methods Study Of Inpatients’ Experiences, Priorities, And Health-Related Quality Of Life During High- Flow Nasal Cannula Therapy, Cintamani H. Ellsworth, Rebecca S. Bartlett

Journal of Patient-Centered Research and Reviews

Purpose: High-flow nasal cannula (HFNC) is an oxygen delivery method with numerous benefits for severely ill patients. There is a paucity of research focused on the perspectives of patients receiving HFNC oxygen therapy. This study aimed to engage with patients to gain a clearer understanding of their experiences, priorities, and health-related quality of life.

Methods: A cross-sectional, mixed methods study was completed with 10 adult inpatients who had received HFNC oxygen therapy during their hospital admission. Semi-structured interviews and the Patient Reported Outcomes Measurement Information System (PROMIS) Global Health Scale were used to identify participant perceptions of their physical and …

Variations In Practice Of Apnea Test For Brain Death: Review From A Multihospital Health Care System, Jeffrey Stein, Marvi V. Rijhwani, Ernesto Brauer

Journal of Patient-Centered Research and Reviews

Background: Ventilation encompasses both active and passive processes. Air is initially drawn into the lungs due to a negative intrathoracic pressure created using the respiratory muscles, most importantly the diaphragm. In contrast, expiration is the passive relaxation of the respiratory muscles. Oxygenation occurs when oxygen diffuses across the alveolar-capillary membrane. The ability to oxygenate without ventilation has been termed apneic diffusion oxygenation or apneic oxygenation. We believe it is crucial to keep alveoli open in order for adequate oxygenation to occur. This can be achieved with the aid of positive end-expiratory pressure (PEEP). We investigated this concept in patients who …
