The incidence of acute respiratory failure (ARF) has dramatically increased in the past few decades in the United States. From 2002 to 2017, there was a 197% increase in the annual incidence of ARF, and in response, a 437% increase in the use of noninvasive mechanical ventilation (NIV). Multiple studies have demonstrated that use of NIV frequently causes communication impairment (CI), which is strongly associated with anxiety and can in turn contribute to NIV intolerance and failure, and ultimately, mortality. CI also prevents accurate evaluation of patients by providers, which can contribute to worse clinical outcomes. Recently, Lee et al at Pohang University, South Korea, published their development of a flexible, wearable vibration sensor that can amplify speech while minimizing ambient noise. Although this device is intended for use in portable devices such as cell phones, it also poses as a viable solution for NIV-related communication impairment.
