Portable, consumer-grade pulse oximeters are accurate for home and medical use: Implications for use in the COVID-19 pandemic and other resource-limited environments.

Objective: To determine the correlation between 3 lightweight portable pulse oximeter devices compared to a standard wall mount pulse oximetry device.

Methods: We performed a single-center, prospective, observational study of 4 pulse oximetry devices, 3 of which are commercially available to the public. A convenience sample of 200 emergency department (ED) patients with chief complaints of cardiopulmonary origin or a peripheral capillary oxygen saturation ≤ 94 percent were enrolled.

Chest Pain From Supplement Use in an Active Duty Soldier: A Case Report.

In the active duty population, over-the-counter performance enhancing supplements are readily available and consumed, primarily in an unsupervised manner. While some of the active ingredients, such as caffeine and creatine, have been well studied, other sympathomimetic and vasoactive components in these products have minimal data regarding their safety profile. Further potentiating the associated risks of consumption, the quantities and purities of the reported ingredients are often unverified and can vary from serving to serving.

Utilization of a Co-enrolled Course Structure for Point-of-Care Ultrasound Training in the Undergraduate Medical Education Setting.

With continuing advancements in software, electronics, and miniaturization, ultrasound (US) is quickly becoming an everyday tool of numerous medical specialties. With the advent of new handheld and other small-scale units, physicians have a tool to obtain on demand imaging without exposing the patient to ionizing radiation in the pocket of their white coat. As such, the need for competency in US is increasing.
