深吸气量（英文名 inspiratory capacity 缩写为 IC）是指从平静呼气末作最大吸气时所能吸入的气体量。从平静呼气末作最大吸气时所能吸入的气量为深吸气量（inspiratory capacity），它是潮气量和补吸气量之和，是衡量最大通气潜力的一个重要指标。

Long-term low-dose erythromycin therapy can reduce airway neutrophil counts and inhibit activity of neutrophils in pations with moderate-to-severe stable COPD.2. Erythromycin therapy can increase significantly inspiratory capacity(IC)and 6MWD,reduce the number of acute exacerbations,and improve quality of life.
结论:长期小剂量红霉素治疗中、重度稳定期COPD患者可以(1)减少中性粒细胞的数量,抑制其活化;(2)提高肺深吸气量(IC)和运功耐力,减少急性加重次数,一定程度改善生活质量。

结果呼吸含60%氦的氦氧混合气体后，肺活量、补呼气容积呈大幅增加，深吸气量呈轻微下降变化，其中补呼气容积前后变化具有显著差异（P<0.05）。
Results: After breathing He-O2 containing 60% helium, VC and ERV increased enormously, while IC decreased mildly, among which the change of ERV showed significant difference (P<0.05).
最大肺活量是指在深吸气之后呼出的最大气量，它与肺功能没有太大关系。
The total amount of air they could blow out after a deep breath was also measured (Forced Vital Capacity, FVC), but there was little effect on this measure.
