Differences in respiratory oscillometry measurements using mouthpiece, mouth, and nasal mask in healthy adults.

Airway resistance measurements using oscillometry provide a potential alternative to spirometry in assessing airway obstruction and dynamics due to measurements taken during tidal breathing. Oscillometry typically requires participants to form a tight seal around a mouthpiece that can prove challenging for some people. To address this challenge, we conducted a prospective study to evaluate the effect of different interfaces like mouthpiece, mouth mask, and nasal mask on respiratory impedance results from oscillometry in a cohort of healthy adults.

Predicting Respiratory Therapists' Intentions to Use the Modified Early Warning Score by Using an Enhanced Technology Acceptance Model.

Background: The modified early warning score (MEWS) is used to detect early clinical deterioration and to escalate care as needed. Respiratory therapists (RTs) usually do not use the MEWS even when it is implemented as a default in the electronic health record system. This study explored whether the technology acceptance model could predict the intentions of RTs to use the MEWS.
