目的：无创通气（NIV）在无创气管插管的情况下提供呼吸支持，但会阻碍患者有效沟通的能力。目前的研究提出了使用新型面罩内呼吸机麦克风在接收NIV时提高通话清晰度的初步结果。方法：概念验证研究使用麦克风原型模型在持续气道正压通气（CPAP; 5/5 cm H2O）和双水平气道正压通气（BiPAP; 8/4 cm H2O）呼吸机条件下评估5名健康成人说话者的句子可理解性。一项初步研究随后评估了8名在重症监护病房（ICU）接受治疗性NIV治疗的患者的可理解性、主观可理解性和自然性，以及患者和谈话伙伴报告的交流结果。结果：在BiPAP条件下，健康志愿者的可理解性随着麦克风的打开而显著提高。对于在ICU接受NIV的患者，在打开麦克风时，可理解性、可理解性以及患者和谈话伙伴对谈话满意度的评分显著提高。在某些测量（可理解性、可理解性）中，基线较低而不使用麦克风的患者通常比基线较高的患者表现出更大的麦克风获益。结论：使用集成在NIV中的新型麦克风可提高健康志愿者和接受治疗性NIV的患者在通气时的可听性。额外的临床研究将确定这种提高可理解性的确切益处和影响。
Purpose:Non-invasive ventilation (NIV) provides respiratory support without invasive endotracheal intubation but can hinder patients’ ability to communicate effectively. The current study presents preliminary results using a novel in-mask ventilator microphone to enhance talker intelligibility while receiving NIV.Method:A proof-of-concept study assessed sentence intelligibility of five healthy adult talkers using a prototype model of the microphone under continuous positive airway pressure (CPAP; 5/5 cm H2O) and bilevel positive airway pressure (BiPAP; 8/4 cm H2O) ventilator conditions. A pilot study then assessed intelligibility, subjective comprehensibility and naturalness, and patient- and conversation partner-reported communication outcomes for eight patients undergoing therapeutic NIV while being treated in an intensive care unit (ICU).Result: Intelligibility increased significantly with the microphone on in the BiPAP condition for healthy volunteers. For patients undergoing NIV in an ICU, intelligibility, comprehensibility, and patient and conversation partner ratings of conversation satisfaction significantly improved with the microphone on. Patients with lower baselines without the microphone in certain measures (intelligibility, comprehensibility) generally showed a greater microphone benefit than patients with higher baselines.Conclusion:Use of a novel microphone integrated into NIV improved intelligibility during ventilation for both healthy volunteers and patients undergoing therapeutic NIV. Additional clinical studies will define precise benefits and implications of such improved intelligibility.
