Pulse oximetry and the enduring neglect of respiratory rate assessment: a commentary on patient surveillance.

Clinical surveillance provides essential data on changes in a patient's condition. The common method for performing this surveillance is the assessment of vital signs. Despite the importance of these signs, research has found that vital signs are not rigorously assessed in clinical practice. Respiratory rate, arguably the most important vital sign, is the most neglected. Poor understanding might contribute to nurses incorrectly valuing oxygen saturation more than respiratory rate. Nurses need to understand ...

Accuracy of a smartphone application for triage of skin lesions based on machine learning algorithms.

Machine learning algorithms achieve expert level accuracy in skin lesion classification based on clinical images. However, it is not yet shown whether these algorithms could have high accuracy when embedded in a smartphone app, where image quality is lower and there is high variability in image taking scenarios by users. In the past, these applications were criticized due to lack of accuracy.

Smartphone Aided Quantification of Iridocorneal Angle.

As the upgrading smartphone technology revolutionizes the field of Ophthalmic imaging, we put forward one more of its novel application.
