DEVICE: Merit Medical® (10884450326456)

A collection of devices that includes the necessary tubing and other items, e.g., connectors, stopcock(s), clamps and filters, used as an external connection for invasive blood pressure measurement. This set will interface, either directly or from an intermediate stopcock, between the applied invasive catheter and the measuring transducer. It will have physical characteristics appropriate for preserving, to the extent possible, the waveform and fidelity of the measured pressure. This is a single-use device.

A collection of sterile devices designed to obtain an in-line arterial blood specimen while maintaining a closed system. It is a haemodynamic pressure monitoring and blood gas sampling device, typically designed for use with disposable/reusable pressure transducers, intended to connect to a central line/arterial catheter from which the blood specimen is obtained. Heparinized blood may be reinfused into the patient via the device to reduce fluid loss. This is a single-patient device that may be used short term (single-use) before being discarded.
