Assessing cardiac function in patients with pulmonary disease requires knowledge of cardiac loading conditions, which can be obtained if the practitioner is aware of physiologic and technical factors that can affect observed pressures and flows. Only with proper care in measuring and interpreting these parameters can therapeutic decisions be made confidently for these patients.
评估肺部疾病患者的心脏功能需要了解心脏负荷情况，而如果从业者知晓可能影响所观察到的压力和流量的生理及技术因素，就能获取这些信息。只有在测量和解读这些参数时予以适当注意，才能为这些患者自信地做出治疗决策。
