What are the common settings on an ECMO pump?

The correct choice focuses on the essential settings that an ECMO pump typically involves for optimal function and patient safety. Blood flow rates are a critical setting, as they determine the volume of blood being circulated through the ECMO circuit per minute, which is crucial for effective oxygenation and removal of carbon dioxide. Speed settings are vital because they control the rate at which the blood is pumped through the circuit, directly impacting the circulatory support provided to the patient. Additionally, pressure alarms are fundamental safety features that alert caregivers to potential issues, such as clot formation or equipment malfunction, ensuring timely intervention when needed.

Other options do not address the primary operational parameters that influence patient care within the ECMO context. For example, temperature and humidity settings, while important in many medical devices, are not typical settings for an ECMO pump. Pressure alarms alone do not encompass the full range of settings necessary for managing the patient's therapy, and parameters like pump weight and surface area are not standard configurations for operational settings, but rather might be relevant in a different context, such as the physical characteristics of the equipment. Hence, focusing on blood flow rates, speed settings, and pressure alarms encompasses the critical aspects of managing ECMO therapy.
