摘　　要：目的：对尘肺患者进行运动负荷试验，以探讨运动试验（ＥＴ）与常规肺功能试验（ＰＦＴ）的关系和劳动能力评价。方法：ＥＴ前做ＰＦＴ。ＰＦＴ正常或轻度损害者为受试对象。以运动时最大每分钟通气量（ＶＥｍａｘ）占最大通气量（ＭＶＶ）预计值比≥６４％为受试者最大运动量。ＥＴ最大氧耗量（ＶＯ２ｍａｘ）实测值参照ＣＴＳ标准评定呼吸功能损害程度并与ＰＦＴ比较。结果：３２例尘肺运动时（ＶＥｍａｘ／ＭＶＶ）达到６４．２１％至１０４．４９％者有１２例（ＰＦＴ正常７例，轻度异常５例），运动终止时测得ＶＯ２ｍａｘ为１９．０４±４．１１ｍｌ／ｋｇ。２１例运动时ＳａＯ２％降低者６例，（ＰＦＴ）正常２例，轻度异常４例。以ＶＯ２ｍａｘ参数评定ＰＦＴ正常的７例呼吸功能，其中６例为轻度损害，１例为中度损害。评定ＰＦＴ轻度异常的５例，３例为轻度，２例为中度损害。结论：ＥＴ能发现个别尘肺患者潜在生理学异常。ＶＯ２ｍａｘ参数评价呼吸功能损害较ＰＦＴ敏感。评定个体劳动能力较ＰＦＴ客观。Objective:In order to approach to the relation between exercise testing (ET) and pulmonary function test(PFT),and work capacity,32 patients with pneumoconiosis performed progressive exercise on a cycle ergometer.Methods:To perform PFT before ET,PFT normal or mild abnormal were selected as subjects.Their maximum exercise capacity at reach maximum expired per minute(E max) of ET (reference to CTS standard) compared to PFT for evaluating respiratory function impairment.Results: In 12 cases (of them 7 cases of PFT normal,5 cases of PFT mild abnormal) of 32 patients with pneumoconiosis,E max/MVV% has from 64% to 104.49%,O2 max ml/kg(mean±SD)∶19.04±4.11 when ET ended.In 21 cases of all patients,dynamic monitoring SaO2% decreased in 6 cases (2 cases PFT normal,4 cases PFT mild abnormal) of them.O2 max parameter evaluating respiratory function,6 cases was with mild impairment and one with moderate impairment of PFT normal,3 cases was of mild impairment and 2 cases of moderate impairment in 5 cases of PFT mild impairment.Conclusion: ET may find individual potential physiological disorder.O2 max parameter assessing respiratory impairment is more sensitive than PFT.ET is more objective for evaluating individual work capacity than PFT.
