Feasibility of Obtaining Pulse Oximetry Readings From the Oropharynx

This is a prospective study to evaluate the feasibility of obtaining a pulse oximetry ready from the oropharynx with a standard oximeter probe that has been attached to an oral airway or a tongue blade. The study will compare the values from the peripheral pulse oximeter on a finger, toe, foot or hand with the that from the oropharyngeal oximeter. The study will also compare the saturation from an arterial blood gas (ABG) collected as standard of care with that obtained from the oropharyngeal oximeter.

Structural and Microbiological Characterization of Arterial Catheter Biofilm in ICU's Patients Using Optical Coherence Tomography

29.3% of bacteremias in intensive care units (ICU) are linked to vascular devices, including 7.7% to arterial catheters, with an influence on both morbility and mortality. It is now accepted that biofilm as a role on bacterial development on inner surface of vascular devices but there is yet a lack of clinical relevant data documenting a causal relation between biofilm formation and bacteremias. The investigators assume that a better structural and microbiological characterization of arterial catheter biofilm in ICU patients could help preventing bacteremias or have a more specific treatment when it appears.
