Objective:
To evaluate the effects of henna on the results of pulse oximetry in healthy women.
Methods:
100 young women (20-60 years of age) were recruited. The Iranian original red henna was used to colour the index finger of THE non-dominant hand; the middle finger of the same hand was the control. Blood oxygen saturation was simultaneously measured by two calibrated pulse oximeters.
Result:
Henna did not affect pulse oximetry measurement of oxygen saturation. There was no statistically significant difference between the control and the henna dyed fingers.
Conclusions:
Henna is not likely to change the accuracy of oxygen saturation measured by pulse oximeter.
Clinical Trial Registration:
20120906159N20.

01:30Equipments 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...
