まとめ
座っているときの肺動脈圧 (PAP) の測定は,心臓機能不全 (HF) の患者における横置状態の測定値と非常に相関しています. 座席でのPAPは,HFのリモート管理のための信頼性の高い代替手段であり,患者のアデンスを改善する可能性があります.
科学分野:
- 心臓病科
- 肺高血圧
- 心不全 の 治療
背景:
- 肺動脈圧 (PAP) のモニタリングは,心不全 (HF) の管理に不可欠です.
- 現在のモニタリングは,患者によってあまり好まれない,寝た状態での測定に依存しています.
- リモート・モニタリングの最適化には 座った状態と横になった状態の PAP の関係を理解することが不可欠です
研究 の 目的:
- 座っているときの肺動脈圧 (PAP) の測定値との相関を調査する.
- 心不全の患者でCordellaTM HF管理システムを用いてPAP測定の有用性を評価する.
主な方法:
- SIRONA 2とPROACTIVE- HF試験のペアリングされた座った状態と座った状態のPAP測定値の分析
- NYHAクラスIIIのHF患者504人のデータを含み,合計40, 115件のペア測定を行った.
- 座った状態と座った状態のPAP測定の相関と差異を特定するための統計分析.
主要な成果:
- 座った状態と横になった状態の間で,平均PAP (r=0. 85),静脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈動脈).
- 座った状態での測定は,座った状態での測定よりも常に高い圧力を示し,その差は圧力レベルによって異なる.
- 座っている状態でのmPAPの傾向は,心不全の入院前の控えめな増加を示した.
結論:
- 座った状態でのPAP測定は,座った状態でのPAP測定と強い相関を示し,PAPセンサーを搭載したHF患者での使用を検証した.
- 静脈の容量と予備負荷の差異は,HFのフェノタイプ化に役立ちます.
- 座った状態でのPAPモニタリングは,HFのリモート管理のための有効で信頼性の高い,そして潜在的に好ましい代替手段であり,従順性を高め,ケアを最適化します.

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

01:28Special considerations while measuring blood pressure
822
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
