BACKGROUND Interplay between the components of a lipoplasty system (suction pump, suction tubing, collection canister, and cannula) determines liposuction efficiency. However, in clinical practice, none of the components are more important than the cannula. Cannula design including port design, port placement, and shaft characteristics is the single most influential contributor to flow resistan...

A reservoir nasal cannula which stores oxygen during exhalation and delivers it as a bolus during inhalation has been reported to conserve oxygen delivery in patients with chronic obstructive pulmonary disease (COPD) at rest. We compared the effects upon arterial oxygen saturation (SaO2) of the reservoir cannula and a standard nasal cannula in hypoxemic obstructed and restricted patients at res...

OBJECTIVE Femoral arterial cannulation is associated with a significant risk of lower limb ischemia. The aim of the study was to assess the pressure and flow in the femoral artery using a novel bidirectional femoral cannula in a sheep model of peripheral cardiopulmonary bypass. METHODS Peripheral cardiopulmonary bypass was established using a multistage venous cannula inserted into the intern...

BACKGROUND Minimally invasive robot-assisted cardiac surgery is generally performed nowadays. To avoid the interference of a superior vena cava (SVC) cannula during surgery, it should be inserted before the operation. The position of this cannula is very important because it can cause poor venous drainage during operation. The proper position of the SVC cannula was investigated in the present s...

OBJECTIVE High-flow humidified nasal cannula is often used to provide noninvasive respiratory support in children. The effect of high-flow humidified nasal cannula on effort of breathing in children has not been objectively studied, and the mechanism by which respiratory support is provided remains unclear. This study uses an objective measure of effort of breathing (Pressure. Rate Product) to ...

BACKGROUND Reduction of atheroembolic complications during cardiopulmonary bypass remains a major challenge in cardiac surgery. New cannula tip designs may help to attenuate this problem by improved hydrodynamics. METHODS Pressure gradients and back pressures of a new aortic cannula tip design were measured and compared with the Medos X-Flow, Sarns Soft-Flow and Argyle THI cannulae at various...

Currently, two types of cannula are available for Medtronic insulin pump therapy: the vertical Quick-set cannula (Medtronic plc, Dublin, Ireland) and the 30-degree angle Silhouette cannula (Medtronic plc). However, it has not been established which cannula should be used in specific patients. Here, we present two Japanese patients with type 1 diabetes who experienced unexpected episodes of hype...

OBJECTIVE A multicycle, quality improvement method was used to standardize nasal cannula O2 administration and weaning in the NICU. METHODS A 2-armed nasal cannula standardized order form (nasal cannula for stable O2 arm and nasal cannula for stable flow arm) was developed after review of the literature, surveying of the practice of NICU physicians and nurse practitioners, and development of ...
