| 测试位置：所有受试者的坐姿 |
| In general SBW only feasible in older children and adults ≥12 yrs |
| 界面 |
| Nose clip and maintain a tight mouthpiece seal |
| 应执行三种技术上可接受的SBW运行，通过以下标准定义可接受性 |
| Within-test criteria |
| No evidence of leak (as described for MBW) |
| Inspiratory and expiratory flow maintained between 400 and 500 mL·s-1在测试机动的前四季度的吸气和呼气部分 |
| Maintaining these flows at end of manoeuvre may be difficult |
| Flow restrictors may be useful to maintain desired flow range |
| Phase III slope default settings to 25–75% of expired volume |
| Manually adjustable to ensure freedom from contamination by phase II, phase IV, and stochastic variations in SIII由低频噪声或心形成振荡引起 |
| Specific to classical VC SBW manoeuvre |
| Inspiratory and expiratory VC breaths within 10% within same test |
| Specific to modified SBW manoeuvre |
| Stable end expiratory level prior to starting the manoeuvre |
| Deviation in end-expiratory lung volume at start of the test within 10% of meanV.T.前五次呼吸 |
| Inspiratory volume above FRC reaches 1 L within±10% |
| Between-test criteria |
| Specific to classical VC manoeuvre |
| Expiratory VC values within 10% of highest value |
| Specific to modified SBW manoeuvre |
| Inspiratory volumes within 10% of 1 L |
| Expiratory volumes within 10% of each other |
| Re-establish baseline inert gas concentration before starting next test |
| N2SBW：终点n2集中率返回基线水平 |
| Exogenous SBW: end-tidal inert gas concentration <1/40 of inspired inert gas concentration |
| Sufficient interval between tests of at least two minutes to stabilise volume history and to reset alveolar N2浓度 |
| 测试设备和性能必须遵守感染控制指南 |
MBW：多口气冲洗;S.III：III阶段坡度;VC：重要的容量;V.T.： 潮量;FRC：功能剩余容量;N.2：氮气。
