What is an example of invasive monitoring equipment?

• A. Electrocardiogram
• B. Pulse oximeter
• C. Arterial catheters
• D. Blood pressure cuff

Answer: (C)

Invasive monitoring equipment is designed to enter the body, providing direct access to physiological parameters that allow for real-time monitoring of a patient’s condition and the ability to perform interventions when necessary. Arterial catheters serve as a prime example of this type of equipment, as they are inserted directly into an artery. This allows for the continuous measurement of blood pressure and the collection of blood samples for laboratory analysis, offering critical information about the patient's hemodynamic status. The other options mentioned do not qualify as invasive monitoring equipment because they do not penetrate the skin or access internal structures. An electrocardiogram monitors heart activity non-invasively by placing electrodes on the skin. A pulse oximeter, similarly, is a non-invasive device that measures oxygen saturation in the blood through a sensor placed on the skin, typically on a fingertip or earlobe. The blood pressure cuff, while essential for assessing blood pressure, does so externally and does not involve any invasive action. Therefore, the arterial catheter stands out as the only invasive method among the choices, allowing for a deeper level of physiological monitoring.
