在2019冠状病毒病大流行期间，使用防护口罩对于减少传染至关重要。然而，公众舆论认为这与主观呼吸短促有关。我们评估了休息和最大运动时的心肺参数，以突出使用防护口罩的任何差异。12名健康受试者进行了3次相同的心肺运动测试，1人不戴防护口罩，1人戴外科口罩，1人戴过滤面片颗粒2级（FFP2）口罩。采用Borg评分法评估呼吸困难。还进行了标准肺功能检查。所有受试者（40.8±12.4岁，6名男性）均完成了方案，无不良事件发生。肺活量测定显示，1 s内用力呼气量（FEV1）和用力肺活量（FVC）从无口罩到手术到FFP2逐渐降低(FEV1: 3.94 +/- 0.91 L、3.23 +/- 0.81 L、2.94 +/- 0.98 L; FVC: 4.70 +/- 1.21 L、3.773 ~ 1.02 L、3.5211.21 L
During the COVID-19 pandemic, the use of protective masks has been essential to reduce contagions. However, public opinion is that there is an associated subjective shortness of breath. We evaluated cardiorespiratory parameters at rest and during maximal exertion to highlight any differences with the use of protective masks.12 healthy subjects performed three identical cardiopulmonary exercise tests, one without wearing a protective mask, one wearing a surgical mask and one with a filtering face piece particles class 2 (FFP2) mask. Dyspnoea was assessed using the Borg scale. Standard pulmonary function tests were also performed.All the subjects (40.8 +/- 12.4 years; six male) completed the protocol with no adverse events. Spirometry showed a progressive reduction of forced expiratory volume in 1 s (FEV1): and forced vital capacity (FVC) from no mask to surgical to FFP2 (FEV1: 3.94 +/- 0.91 L, 3.23 +/- 0.81 L, 2.94 +/- 0.98 L; FVC: 4.70 +/- 1.21 L, 3.773_1.02 L, 3.5211.21 L; p
