Web15 de jul. de 2024 · The central venous pressure can be measured using a central venous catheter advanced via the internal jugular vein and placed in the superior vena cava near the right atrium. A normal central venous pressure reading is between 8 to 12 mmHg. This value is altered by volume status and/or venous compliance. [1] [2] [3] WebCentimeters of Water Column is a manometric unit used to relate a pressure reading to the height of fresh water at a temperature of 4 degC. 1 centimeter of water gauge equals 98.0665 pascals. The cmH2O pressure unit is mostly used to measure breathing on respirators and ventilators which are used in medical and physiological applications such ...
