The method used to measure direct blood pressure is called invasive blood pressure monitoring. This involves inserting a catheter into an artery, typically the radial artery in the wrist or the femoral artery in the groin, to directly measure the pressure of the blood flowing through the artery. This method provides a more accurate and continuous measurement of blood pressure compared to non-invasive methods such as using a blood pressure cuff.

Direct Blood Pressure Measurement
Direct blood pressure measurement involves inserting a catheter into an artery and measuring the pressure inside the artery using a pressure transducer.
Method:
1. Arterial puncture: A needle or catheter is inserted into the lumen of an artery, such as the radial, brachial, or femoral artery.
2. Catheterization: A thin, flexible catheter is threaded through the needle into the artery.
3. Pressure transducer: The catheter is connected to a pressure transducer, which converts the pressure changes in the artery into an electrical signal.
4. Recording: The electrical signal is displayed on a monitor or recorded for analysis.
Advantages:
- Provides the most accurate measurement of blood pressure.
- Allows for continuous monitoring of blood pressure over time.
- Can be used in a variety of clinical settings, including surgery and critical care.
Disadvantages:
- Invasive procedure that requires arterial access.
- Can be painful and uncomfortable for the patient.
- Carries a risk of complications, such as bleeding, infection, and arterial damage.
- Requires specialized training and equipment.
