可靠、准确和非侵入性的方法来测量婴儿的肺功能是可取的。电磁感应体积描记法已被用于进行婴儿肺量测定，而VoluSense Pediatrics（VSP）（VoluSense，卑尔根，挪威）代表了该技术的更新版本。我们的目的是检查其准确性相比，一个经过验证的系统测量气流通过面罩使用超声波流量计。我们测试了30名婴儿，月经后年龄在36至43周之间，体重在2.3至4.8公斤之间，同时使用两种方法和单独使用VSP。 使用Bland-Altman分析计算方法之间的一致性，我们还估计了应用面罩的效果。所有呼吸参数的平均差异均在±5.5%范围内，两种方法之间的一致性限度是可接受的，可能潮气峰呼气流量（PTEF）除外。面罩的应用显著增加了潮气量、每分钟通气量、PTEF、吸气与呼气时间的比值以及呼气流量占呼气量的50%时与PTEF的比值。VSP可准确测量潮式呼吸参数，似乎非常适合使用排除使用面罩的设备治疗的婴儿的潮式呼吸测量。
Reliable, accurate and noninvasive methods for measuring lung function in infants are desirable. Electromagnetic inductance plethysmography has been used to perform infant spirometry and VoluSense Pediatrics (VSP) (VoluSense, Bergen, Norway) represents an updated version of this technique. We aimed to examine its accuracy compared to a validated system measuring airflow via a facemask using an ultrasonic flowmeter. We tested 30 infants with postmenstrual ages between 36 to 43 weeks and weights from 2.3 to 4.8 kg, applying both methods simultaneously and applying VSP alone. Agreement between the methods was calculated using Bland-Altman analyses and we also estimated the effect of applying the mask. Mean differences for all breathing parameters were within ±5.5% and limits of agreement between the two methods were acceptable, except perhaps for peak tidal expiratory flow (PTEF). Application of the facemask significantly increased tidal volume, minute ventilation, PTEF, the ratio of inspiratory to expiratory time and the ratio of expiratory flow at 50% of expired volume to PTEF. VSP accurately measured tidal breathing parameters and seems well suited for tidal breathing measurements in infants under treatment with equipment that precludes the use of a facemask.
