Objective: Compare ventilation pressures of 2 endotracheal tube designs used in laser airway surgery clinical practice and with a benchtop model to elucidate differences understand the design elements that impact airflow dynamics. Methods: Ventilatory aerodynamic characteristics resistant stainless-steel (LRSS-ET) aluminum-wrapped silicone (LRAS-ET) were compared. parameters collected for 32 patients undergoing laser-assisted through retrospective chart review. An vitro simulation measured...
Wearable and implantable technology for respiratory monitoring has created the potential continuous collection of parameters healthcare other applications. However, battery life, form factor, user burden impose practical constraints that affect acceptance therefore clinical utility. This work introduces a wireless self-powered sensing system airway uses an array piezoelectric cantilevers functions as both flow sensor energy harvester powers system. The are excited by airflow in airway,...
Piezoelectric materials are widely used to generate electric charge from mechanical deformation or vice versa. These strategies increasingly common in implantable medical devices, where sensing must be done on small scales. In the case of a flow rate sensor, sensor's energy harvesting could mapped that rate, making it 'self-powered by design (SPD)'. Prior fluids-based SPD work has focused turbulence-driven resonance and been largely empirical. Here, we explore possibility sub-resonant human...
Central airway obstruction (CAO) is a respiratory disorder characterized by the blockage of trachea and/or main bronchi that can be life-threatening. Airway stenting palliative procedure for CAO commonly used given its efficacy. However, mucus impaction, secretion retention, and granulation tissue growth are known complications counteract stent's benefits. To prevent these situations, patients routinely brought into hospital to check stent patency, incurring burden patient health care...
