Objectives:
to characterize oscillometric blood pressure measurement devices for sale in the virtual market and identify which ones have undergone a validation study.
Methods:
this was a cross sectional study. The search for devices for sale was conducted on websites, and the sample was composed of 137 devices obtained from 644 ads. We conducted a bibliographic survey in five databases and web pages enlisting devices submitted for validation. The Kolmogorov-Smirnov test was used to check data distribution, followed by Mann-Whitney and Kruskal-Wallis tests for comparisons, using the SAS 9.4 program.
Results:
only 16.7% of the devices were validated. The home devices ranged from USD 10.57 to USD 275.67. Only 102 ads informed the cuff size, with different nomenclatures.
Conclusions:
most ads contained non-validated devices, which were cheaper. We identified some ads falsely informing validation.

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...

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.
