Pulmonary overinflation syndrome in an underwater logger.

Cave Pearl Data Logger: A Flexible Arduino-Based Logging Platform for Long-Term Monitoring in Harsh Environments

A low-cost data logging platform is presented that provides long-term operation in remote or submerged environments. Three premade "breakout boards" from the open-source Arduino ecosystem are assembled into the core of the data logger. Power optimization techniques are presented which extend the operational life of this module-based design to >1 year on three alkaline AA batteries. Robust under...

Observability Analysis of DVL/PS Aided INS for a Maneuvering AUV

Recently, ocean exploration has increased considerably through the use of autonomous underwater vehicles (AUV). A key enabling technology is the precision of the AUV navigation capability. In this paper, we focus on understanding the limitation of the AUV navigation system. That is, what are the observable error-states for different maneuvering types of the AUV? Since analyzing the performance ...

Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC synd...

Endotracheal tube lumen compromise from cuff overinflation.

A chest roentgenogram demonstrates lumen collapse as the cause of ventilatory obstruction in an intubated patient. This problem is not restricted to defective tubes but may be caused by overinflation of the cuff in normal tubes. D espite the impressive record of endotracheal tubes as guardians of an unobstructed airway, human and mechanical failure causing these devices to become dangerous site...
