Blood pressure and oxygen saturation measurement on arms and legs
This examination allows you to simultaneously assess blood pressure and oxygen saturation in different parts of the body – the arms and legs. It provides valuable information about the characteristics of blood circulation and possible disorders.
What is it?
This examination is similar to a regular blood pressure and oxygen level measurement, but it is performed simultaneously in several places on the body – on the arms and legs.
This allows the doctor to compare blood pressure and oxygen saturation in different parts of the body, which is especially important if congenital heart disease or circulatory disorders are suspected.
How is it done?
Before starting the measurement, the patient needs to be at rest for about 5 minutes, sitting or lying down, so that the readings are as accurate as possible.
During the examination, blood pressure cuffs are placed on the patient's arms and legs in turn, similar to a regular blood pressure measurement. Measuring the pressure on the leg may cause temporary discomfort, as the pressure is usually more noticeable than on the arm.
Then, or at the same time, a small oxygen level sensor is placed on the finger, which measures how well the blood is saturated with oxygen.
The test takes approximately 10 to 15 minutes, including preparation time before the measurements. It can be performed as a stand-alone examination or as part of a doctor's consultation and comprehensive heart health evaluation.
When is it needed?
This measurement is most often performed:
-
if congenital heart defects are suspected;
-
during a regular visit for patients with congenital heart disease;
-
if it is necessary to assess differences in blood pressure or oxygen saturation between the upper and lower parts of the body;
-
if circulatory disorders are suspected.
How to prepare?
No special preparation is required, but a few simple suggestions will help ensure more accurate results:
-
Rest for 5–10 minutes before the examination to allow your blood pressure to stabilize.
-
Do not eat or drink caffeinated beverages (coffee, energy drinks) at least 1–2 hours before your visit.
-
Avoid smoking immediately before the test, as it may affect the results.
-
Choose comfortable clothing that allows you to easily free your arms and legs for the blood pressure cuff.
-
If you are taking medication, continue taking it as usual unless your doctor tells you otherwise.
