The incidence of heart failure as well as its treatment costs and rehospitalization rates are increasing worldwide. Physical assessment of elderly patients with heart failure living in their homes is challenging for community nurses. Pocket-sized echocardiographs will be useful for assessing the condition of the patients with heart failure during home-visit care. This pilot study aimed to examine the feasibility of measuring the inferior vena cava (IVC) diameter using a pocket-sized ultrasound device. Nursing students were trained to use the pocket-sized ultrasound device (PUSD) for measuring the inferior vena cava diameter of a healthy subject. We evaluated the accuracy and rapidity of the nursing students' measurements compared with those of an expert sonographer. In total, 83.3% of the participants accurately visualized the IVC using the PSUD. There was no significant difference in the mean IVC diameter between that measured by the students and the sonographer. In total, 25% of the participants accurately measured the IVC diameter. The mean measurement time was 201 seconds. Our training program allowed the participants to accurately visualize the IVC using the PSUD. However, these results on accuracy and measurement time still need to be improved before community nurses can use the PSUD during home visits.
心力衰竭的发病率以及其治疗费用和再住院率在全球范围内都呈上升趋势。对于在自己家中居住的老年心力衰竭患者，社区护士对其进行身体评估是具有挑战性的。袖珍式超声心动图将有助于在居家护理期间评估心力衰竭患者的病情。本研究旨在检验使用袖珍式超声设备测量下腔静脉（IVC）直径的可行性。培训护理学生使用袖珍式超声设备（PUSD）测量健康受试者的下腔静脉直径。我们评估了护理学生测量结果的准确性和快速性，并与专家超声医生的测量结果进行了比较。 共有 83.3%的参与者使用 PSUD 准确地观察到了 IVC。学生和超声医生测量的 IVC 直径平均值之间没有显著差异。共有 25%的参与者准确测量了 IVC 直径。平均测量时间为 201 秒。 我们的培训计划使参与者能够使用 PSUD 准确地观察 IVC。然而，在社区护士能够在居家访问期间使用 PSUD 之前，还需要进一步提高准确性和测量时间的这些结果。
