Pulse oximetry: Principles and limitations
TL;DR: The principles of pulse oximetry are reviewed, with an eye toward recognizing the limitations of this tool, which include performance limitations in the settings of carboxyhemoglobinemia, methemoglobeinema, motion artifact, hypotension, vasoconstriction, and anemia.
Journal ArticleDOI
Pulse oximetry
TL;DR: In this paper, a review on pulse oximetry that was published in 1999 in Critical Care was updated and a summary of the recently developed multi-wavelength pulse oximeters and their ability in detecting dyshemoglobins was provided.

Evaluation of the ulnopalmar arterial arches with pulse oximetry and plethysmography: comparison with the Allen's test in 1010 patients.
TL;DR: In the evaluation of hand collaterals, PL and OX were found to be more sensitive than MAT and when applied to transradial approach screening, only 1.5% of patients were not suitable candidates for the transradIAL approach.
Journal ArticleDOI
Radial artery cannulation: a comprehensive review of recent anatomic and physiologic investigations.
TL;DR: Limited clinical experience with the ultrasound-guided arterial cannulation method suggests that this technique is associated with increased success of cannulation with fewer attempts, and research is needed to assess the safety of using the ulnar artery as an alternative to radial artery cannulation.

Meta-analysis of arterial oxygen saturation monitoring by pulse oximetry in adults****
TL;DR: Pulse oximeters were found to be accurate within 2% or 5% of in vitro oximetry in the range of 70% to 100% Sao2 and in comparing ear and finger probes, readings from finger probes were more accurate.
