OBJECTIVE To investigate whether deranged physiologic parameters at admission to an ICU in Tanzania are associated with in-hospital mortality and compare single deranged physiologic parameters to a more complex scoring system. DESIGN Prospective, observational cohort study of patient notes and admission records. Data were collected on vital signs at admission to the ICU, patient characteristi...

When invasively assessing coronary artery disease, the primary goal should be to determine whether the disease is causing a patient's symptoms and whether it is likely to cause future cardiac events. The presence of myocardial ischemia is our best gauge of whether a lesion is responsible for symptoms and likely to result in a future cardiac event. In the catheterization laboratory, fractional f...

Optoacoustic (photoacoustic) technique is a novel diagnostic platform that can be used for noninvasive measurements of physiologic variables, functional imaging, and hemodynamic monitoring. This technique is based on generation and time-resolved detection of optoacoustic (thermoelastic) waves generated in tissue by short optical pulses. This provides probing of tissues and individual blood vess...

Employing a team composed of physicians, electrical engineers, and specialists in physical education, significant dynamic physiological data has been gathered by means of radiotelemetry from athletes undergoing strenuous effort, participating in team sports, and from spectators viewing football games. Using a transistorized A.M.-F.M. transmitter carried in a padded compartment strapped comforta...

Spirometry is the most useful and commonly available tests of pulmonary function. It is a physiological test that measures individual inhalation and exhalation volumes of air as a function of time. Pulmonologists and general-practice physicians commonly use spirometry in their offices in the assessment and management of lung disease. Spirometric indices are well validated and easily interpreted...

background: tick and tenacious secretions is one of the problems in suctioning and the instillation of normal saline in airways is one of the ways for removing pulmonary secretions. the aim of this study was to determine the effect of endotracheal suctioning using or not using normal saline on respiratory physiologic parameters in open heart surgery patients. methods: this study was a one-group...
