呼吸跟踪对于肺功能、运动生理学和能量消耗的评估至关重要。传统的方法需要使用通过管连接到固定设备的面罩或吹口，限制位置、移动甚至姿势。为了获得代表患者在不同场景期间的真实状态的准确呼吸生理参数，高度优选对患者在自由生活条件下的活动具有较少干预的可穿戴技术。在这里，我们提出了一种小型化，可靠，宽动态范围的流量传感技术，是免疫的方向，运动和噪音。据我们所知，这是第一个引入完全集成的面罩设备的工作，专注于自由生活条件下的呼吸跟踪。实现这一目标面临两个关键挑战：小型化流量传感和消除运动引起的伪影。为了应对这些挑战，我们提出了两项技术创新：1）在硬件方面，我们设计了一种基于压差Pneumotach方法和运动传感的集成流量传感技术; 2）在软件方面，我们开发了基于基线跟踪和定位以及运动补偿的综合算法。实验证明了该技术的有效性。模拟器和真实的呼吸条件下的实验结果表明，与参考方法计算的值相比，分钟通气量（VE）具有较高的相关性（R2分别为0.9994和0.9964），平均误差在2.5%以内。这些结果表明，所提出的方法是准确和可靠的跟踪关键呼吸参数在自由生活条件。
Breathing tracking is critical for the assessment of lung functions, exercise physiologies, and energy expenditure. Conventional methods require using a face mask or mouthpiece that is connected to a stationary equipment through a tube, restricting the location, movement, or even the posture. To obtain accurate breathing physiology parameters that represent the true state of the patient during different scenarios, a wearable technology that has less intervention to patient’s activities in free-living conditions is highly preferred. Here, we propose a miniaturized, reliable, and wide-dynamic ranged flow sensing technology that is immune to orientation, movement, and noise. As far as we know, this is the first work of introducing a fully integrated mask device focusing on breath tracking in free-living conditions. There are two key challenges for achieving this goal: miniaturized flow sensing and motion-induced artifacts elimination. To address these challenges, we come up with two technical innovations: 1) in hardware wise, we have designed an integrated flow sensing technique based on differential pressure Pneumotach approach and motion sensing; 2) in software wise, we have developed comprehensive algorithms based baseline tracking and orientation and motion compensation. The effectiveness of the proposed technology has been proven by the experiments. Experimental results from simulator and real breath conditions show high correlation (R2 = 0.9994 and 0.9964 respectively) and mean error within 2.5% for Minute Volume (VE), when compared to values computed from reference methods. These results show that the proposed method is accurate and reliable to track the key breath parameters in free-living conditions.
