Abstract: A system for monitoring an ablation procedure in a target tissue includes a first light source for delivering light to the target tissue to generate photoacoustic signals and a second light source for delivering light to the target tissue for ablation therapy. The system further includes a beam mixer for receiving light from the first and second light sources to create a combined light beam. An ablation catheter including a single optical fiber receives the combined light beam from the beam mixer, wherein the combined light beam is emitted from a tip of the ablation catheter to perform simultaneous ablation therapy and photoacoustic monitoring of the ablation procedure in the target tissue in real time.

Abstract: Techniques regarding a nose to tragus length measuring tape for determining an endotracheal tube insertion depth are provided. For example, in one or more embodiments a measuring tape is provided, which can comprise an indicium representing an insertion depth of an endotracheal tube based upon a direct correlation between a nasal to tragus length of a patient and the insertion depth.
