2018年4月11日 · ☆ 看 fluid responsiveness 最重要的指標是 pulse pressure variation (PPV) 與 stroke volume variation (SSV)。 ☆ 一個呼吸週期,有胸內壓力的高低, 進而會去影響到心臟的容積多寡, 造成心搏輸出量的改變與脈壓的改變。 ☆ 在呼吸器使用,沒有自發性呼吸與規則心跳的三個前提下,一個呼吸週期影響脈壓 (pulse pressure) 或心搏輸出量 (stroke volume) 的百分比,變可以看出是否具有輸液反應性。 ☆ 若容積越低,在一個呼吸週期影響脈壓 (pulse pressure) 或心搏輸出 …

2022年6月29日 · 心搏量變異率( Stroke volume variation, SVV ): 正常值12-15%表示每一次心搏輸出的差異程度,臨床上常用作判讀輸液量是否足夠的指標,心搏量易受正壓呼吸器使用而在吸氣期增加,在吐氣期減少,此數值可用做輸液指標,一般來說會以SVV 低於12%會被認為volume 足 …

ICON: Non-invasive CO Hemodynamic Monitoring - dot medical
The ICON is one of the few devices FDA approved for use in Adults, Children and Neonates which requires no inter-patient calibration. By attaching only 4 standard sensing electrodes to the patients neck and torso the device can quickly provide Heart Rate, Stroke Volume, and Cardiac Output as well as another seventeen derived clinical parameters.
With the ICON and AESCULON, the user gets a com-plete picture of the patient hemodynamics using a method that is quick, easy, safe, non Invasive and accu-rate. The parameters provided by EC fill in the blanks of traditional monitoring, helping physicians guide fluid resuscitation and drug therapy in a targeted, continu-ous manner.

Stroke volume variation (SVV) 的應用與限制 - Blogger
Stoke volume variation (SVV)的理論基礎是: 原本心臟在正常跳動時,即使是規則的心跳,每一次心跳所打出的stroke volume仍然有一點點差異,這個差異就稱為stroke volume variation。 使用呼吸器的病人,在吸氣期,呼吸器出力把氣體送進胸腔內,會造成胸內壓上升,
