We propose the use of the 1-minute sit-to-stand test (1STST) to evaluate the physical capacity and exertional desaturation one month after discharge in a sample of patients who survived COVID-19 pneumonia. This was a cross-sectional study that collected routine data from consecutive patients admitted to the outpatient program in a public hospital in Chile. Patients were asked to complete a 1STST. Data were analyzed according to those with and without a prolonged hospital stay of >10 days. Eighty-three percent of the patients were able to complete the test (N = 50). The median age was 62.7 ± 12.5 years. The average number of repetitions in the 1STST was 20.9 ± 4.8. Thirty-two percent of patients had a decrease in pulse oxygen saturation (SpO₂) ≥ 4 points. The prolonged hospital stay subgroup had a significant increase in exertional desaturation (mean difference = 2.6; 95% CI = 1.2 to 3.9; p = 0.001) and dyspnea (mean difference = 1.1; 95% CI = 0.4 to 2.1; p = 0.042) compared to the group of length of stay ≤10 days. In-hospital survivors of COVID-19, the 1STST showed a decrease in physical capacity at one month in those 90% who were able to complete it. The 1STST was able to discriminate between those with and without a prolonged hospital stay and was able to detect exertional desaturation in some patients.

我们建议使用 1 分钟坐站测试 (1STST) 来评估 COVID-19 肺炎幸存者样本出院一个月后的身体能力和运动去饱和度。这是一项横断面研究，收集了智利一家公立医院门诊项目连续收治的患者的常规数据。患者被要求完成 1STST。根据有和没有延长住院>10天的患者对数据进行分析。百分之八十三的患者能够完成测试（N = 50）。中位年龄为 62.7 ± 12.5 岁。 1STST 的平均重复次数为 20.9 ± 4.8。 32% 的患者脉搏氧饱和度 (SpO ₂ ) 下降≥ 4 点。长期住院亚组的劳力性去饱和度（平均差 = 2.6；95% CI = 1.2 至 3.9；p = 0.001）和呼吸困难（平均差 = 1.1；95% CI = 0.4 至 2.1；p = 0.042）显着增加。与住院时间≤10天的组相比。对于住院的 COVID-19 幸存者，第 1 次测试显示，90% 能够完成测试的人在 1 个月后身体能力有所下降。 1STST 能够区分住院时间较长和未住院时间较长的患者，并能够检测某些患者的劳力性去饱和度。
