The results of IBP observed more accurate when compared with the indirect technique (N I B P). The distinct advantages of blood pressure readings in Invasive blood pressure & NIBP, like the accessibility of various locations for measuring pressure in a body. Normal blood pressure diastolic and systolic
I B P is a time-proven technique for real-time BP measurement. Invasive BP measurement also knew the direct method of BP measurement.
Patient preparation
The following actions apply to transducers only. (For other transducer types, refer to the manufacturers recommended assembly instruction)
Turn on the monitor and plug in the pressure cable, or cables in case of double pressure option.
The blood clots not allowed to form in the catheter. This achieved by continuous flushing with the saline solution.
The rate of flow limited to 3 to 5 ml/hr by a flushing device, which does not alter the pressure recording. Prepare the pressure line and transducer by flushing saline solution through the system. Ensure that the system free of air bubbles. (Even small bubbles will distort reading).
Pressure Transducer
Keep ready Transducing with Pressure monitoring line to connect the arterial line for monitoring.
For a complete guide of Pressure Transducer
Read on the above link how to connect and zero pressure transducer in full details
The fluid connected and infuse the air in a pressure bag, inflate the bag to 300 mmHg. 4. Connect the patient catheter to the pressure line, making sure that no air is trapped.
Position the transducer at the site at which blood pressure measured. Generally positioned in the mid-chest position. The transducer level is then set to the patient’s mid-chest level).
Close the pressure line to the patient and open the transducer venting stopcock to the atmosphere. Zero the monitor by pressing zero key
Close the venting stopcock to the atmosphere, and open the stopcock to the patient.
Normal Blood pressure diastolic: 80mm Hg
Normal blood pressure systolic: 120mm Hg
Now ready to begin monitoring.
Following accessories used for measuring blood pressure readings:
Disposable Blood Pressure Transducer
Reusable Interface Cable from one of the above mentioned makes for disposable transducers.
Reusable Blood Pressure Transducer
Note
The keep the transducer at heart level or Midaxillary line
