PRESSURE ENHANCED OXIMETRY & COMBINED PRESSURE MONITOR

描述了一种结合了脉冲技术的发展 血氧测定仪和光体积测定仪用于生产连续和非接触式监护仪 无创血压(CNIBP)和动脉血氧饱和度(SaO2)， 互补的组合，提供互惠的增强 从一个量度到另一个量度。其中最重要的是 增强功能是提高了SaO2的准确性和可靠性 测量，由CNIBP数据提供。这种对SaO2的“增压” 有可能消除与降低的血氧含量相关的误差 皮肤血液流动；从而开启了实践的机会 危重病人血氧饱和度的无创性评估。 成本、可靠性和简单性的优势应该可以实现这一点 有竞争力的联合机组在连续血氧饱和度较高的手术室 CNIBP监测是公认的需要。精确度的优势， 可靠性和患者舒适性应该会打开重症监护市场 对于SaO2和CNIBP的非侵入性监测-这是一个到目前为止 脉搏血氧仪几乎没有渗透。通过提供高质量 同时监测SzO2和CNIBP，该仪器将在许多方面提供 使用动脉管道的一种实际替代方案及其 相关风险。

Described is a development which combines the technologies of pulse oximetry and photoplethysmography for producing a monitor of Continuous and Non-Invasive Blood Pressure (CNIBP) and arterial oxygen saturation (SaO2), a complimentary combination which provides mutually reciprocal enhancements of one measurement to the other. The most significant of these enhancements is the improvement in accuracy and reliability of SaO2 measurements, provided by CNIBP data. This "pressure enhancement" to SaO2 has the potential for eliminating oximetric errors associated with reduced cutaneous blood flow; thereby opening the opportunity for practical noninvasive assessment of SaO2 in critically ill patients. The advantages of cost, reliability, and simplicity should render this combination unit competitive in the operating room where continuous SaO2 and CNIBP monitoring is a recognized need. The advantages of accuracy, reliability, and patient comfort should open up the intensive care market for noninvasive monitoring of SaO2 and CNIBP - a market area which so far has had little penetration by pulse oximetry. By providing quality monitoring of both SzO2 and CNIBP, this instrument would offer in many situations a practical alternative to the use of arterial lines and their associated risks.
