Description of intervention(s) / exposure
The Oscar 2 is an automated device that has been shown to reliably and accurately measure mean pressures in the critically ill patient population. The performance of this device will be examined during aero-medical transportation of 15 patients.

Comparator / control treatment
Numeric integrated intra-arterial mean pressures recorded on the patient monitor have been shown to be interchangeable with high fidelity intra-arterial mean pressures, and as such, will be used as the reference standard against which to test Oscar 2 accuracy.
