Physics of Invasive Blood Pressure Monitoring

Techniques for Non-Invasive Monitoring of Arterial Blood Pressure

Since both, hypotension and hypertension, can potentially impair the function of vital organs such as heart, brain, or kidneys, monitoring of arterial blood pressure (BP) is a mainstay of hemodynamic monitoring in acutely or critically ill patients. Arterial BP can either be obtained invasively via an arterial catheter or non-invasively. Non-invasive BP measurement provides either intermittent ...

Non Invasive Blood Pressure

Alongside heart rate, Blood Pressure is one of the physiological parameters which has been measured by clinicians for the longest period of time: it was known to be important in the 16 century. It remains one of the most important physiological indicators to date and is also one of the more awkward parameters to measure. As has been discussed, blood is pumped round the body by the heart. The bl...

Invasive Pressure Monitoring: General Principles

The sophistication of bedside intensive care unit (ICU) monitoring equipment and the precision of its displayed values may tempt clinicians to accept these data without question. However, critically ill patients place substantial demands on these measurement technologies. Although the technology is governed by rigorous industry standards, it is not foolproof. To ensure accuracy and recognize an...

Noninvasive blood pressure monitoring.

For more 20 years, noninvasive blood pressure (NIBP) monitors have been widely used in operating rooms and critical care units to closely monitor blood pressure in patients of all ages. Despite the widespread use of automated blood pressure monitors, clinicians continue to deliberate over the accuracy and reliability of automated NIBP devices compared to other methods of blood pressure determin...
