Abstract:
Blood pressure measurement is one of the most frequently performed medical procedures. However, oscillometric BP measuring devices have some technical limitation and alternative techniques should be considered. Manual auscultatory measurement is the preferred technique in atrial fibrillation. The BP in patients with left ventricular assist device can be estimated using a manual sphygmomanometer combined with Doppler opening signal. In patients with stenosing arterial disease of the upper limbs, the systolic BP can be estimated at lower extremities using a manual sphygmomanometer on the leg combined with pulse oximetry on the toe.

Special considerations while measuring blood pressure
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.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
