High-volume, low-pressure cuffs. Are they always low pressure?
Ischemic tracheal complications due to the ETT cuff occur in approximately 10 percent of mechanically ventilated critically ill patients despite the use of high-volume, low-pressure ETT cuffs. Using a laboratory model, we studied the effects of airway pressure on three different ETT cuff designs, including two "low pressure" designs. Positive airway pressure acted on the "low pressure" cuffs to...
متن کاملAre Cloudlets Necessary?
We present experimental results from Wi-Fi and 4G LTE networks to validate the intuition that low end-to-end latency of cloud services improves application response time and reduces energy consumption on mobile devices. We focus specifically on computational offloading as a cloud service. Using a wide range of applications, and exploring both pre-partitioned and dynamically partitioned approach...
متن کاملAre the additional grafts necessary?
The goals of surgery for spinal deformity are to correct or improve the deformity to get a stable, balanced and fused spine. The long-term success of any procedure for scoliosis depends on a solid arthrodesis. Getting fusion of the instrumented segment with the aid of copious autogenous iliac graft has been the most important goal of treatment. However, harvesting copious graft from teenage ili...
متن کاملWhen Are Zero Modes Necessary ?
In this paper we develop a way to count zero momentum modes in front-form quantization and apply it to several such approaches: canonical light-cone quantization; Dirac light-cone quantization; reduced phase space quantization ; and Penrose quantization. We also examine which of these light-cone methods are consistent with the Atiyah-Singer index theorem.
متن کاملAre their spectacles really necessary?
an experienced ophthalmic optician, I am also the Scottish representative of the British College of Ophthalmic Opticians and chairman of the National Optical Consultative Committee. The main defect in your editorial lies in the assumption that '80-90% of the prescriptions' for the 516 wearers of supposedly unnecessary spectacles out of 13 800 school children aged 10 years or less 'have been iss...
