repeated bone marrow examination was found to be of value in assessing response to treatment in megaloblastic anemia. the objective of this study was monitoring the response of megaloblastics to treatment, concerning the location of neutrophilic myeloperoxidase and myeloperoxidase index (mpxi) and their variation in megaloblastic erythroid progeny. it is possible to follow up megaloblastic case...
purpose: patterned breathing allows standardized serial measurements of heart rate variability and baroreflex indices. the slow breathing augments these parameters, and regular exercises, including yoga breathing practices with even respiratory rates have long-term beneficial effects in cardiovascular diseases. the role of temporization of breathing phases, i.e. the ratio of expiration to inspi...
Hyperventilation following head injury: effect on ischemic burden and cerebral oxidative metabolism.
OBJECTIVE To determine whether hyperventilation exacerbates cerebral ischemia and compromises oxygen metabolism (CMRO2) following closed head injury. DESIGN A prospective interventional study. SETTING A specialist neurocritical care unit. PATIENTS Ten healthy volunteers and 30 patients within 10 days of closed head injury. INTERVENTIONS Subjects underwent oxygen-15 positron emission tom...
Heart period variability (HPV) metrics have been suggested for use in medical monitoring of trauma patients. This study sought to ascertain the use of various HPV metrics in tracking central blood volume during simulated hemorrhage in individual humans. One hundred one healthy nonsmoking volunteers (58 men, 43 women) were instrumented for continuous measurement of electrocardiogram and beat-by-...
