Anatomic dead space cannot be predicted by body weight.
BACKGROUND Anatomic dead space (also called airway or tracheal dead space) is the part of the tidal volume that does not participate in gas exchange. Some contemporary ventilation protocols, such as the Acute Respiratory Distress Syndrome Network protocol, call for smaller tidal volumes than were traditionally delivered. With smaller tidal volumes, the percentage of each delivered breath that i...
متن کاملStrong earthquakes can be predicted: a multidisciplinary method for strong earthquake prediction
The imminent prediction on a group of strong earthquakes that occurred in Xinjiang, China in April 1997 is introduced in detail. The prediction was made on the basis of comprehensive analyses on the results obtained by multiple innovative methods including measurements of crustal stress, observation of infrasonic wave in an ultra low frequency range, and recording of abnormal behavior of certai...
متن کاملWhy Machines Cannot be
Mental processes are abstracted from a subset of the physical universe ; these, in turn, lead to the world of ideas. Although these ideas include quantum logic, no credible way has yet been found that constructs machines which use superimposed possibilities in the style of quantum logic, more general in computing power to machines based on classical logic. Machine theories are based exclusively...
متن کاملMetastatic melanoma patients’ sensitivity to ipilimumab cannot be predicted by tumor characteristics
Immune checkpoint inhibitors have dramatically changed the prognosis for patients with metastatic melanoma. However, not all patients respond to therapy and toxicities can be severe leaving need for reliable clinical predictive markers. Methods We examined primary tumor characteristics including ulceration, BRAF mutation status, and Breslow depth in patients who subsequently developed stage I...
متن کاملBone mineralisation in premature infants cannot be predicted from serum alkaline phosphatase or serum phosphate.
BACKGROUND The bone mineral content of premature infants at term is lower than in mature infants at the same postconceptional age. Serum alkaline phosphatase and serum phosphate are often used as indicators of bone mineralisation. OBJECTIVE To analyse the association between bone mineral content and serum alkaline phosphatase and serum phosphate. METHODS Serum alkaline phosphatase and phosp...
