Purpose: To determine the actual vacuum pressure generated by the Oertli CataRhex 3 (Oertli), using an external measuring system.
Methods: The effective vacuum pressure created by the Oertli was measured with a pressure device that was continuous with the vacuum tubing system while closed to the external environment. Measurements were taken with the machine set to 300 and 500 mmHg at flow rates of 20, 35, and 50 mL/min and at bottle heights of 60, 80, and 100 cm.
Purpose: To evaluate the effect of each of the tip sizes available for the Oertli CataRhex3 phacoemulsification machine on efficiency.
Methods: Porcine lenses were fixed in formalin for 2 hours, then cut into 3.0 mm cubes.
Background: Emergency department based Physical Therapy (ED-PT) has been practiced globally in various forms for over 20 years and is an emerging resource in the US. While there is a growing body of evidence suggesting that ED-PT has a positive effect on a number of clinical and operational outcomes in patients presenting with musculoskeletal (MSK) pain, there are few published narratives that quantify this in the US. Although there are international papers that offer outcome data on reduction of pain, imaging, throughput time, and the ability of physical therapists to appropriately manage MSK conditions in the ED setting, most papers to date have been descriptive in nature.
