from which (1.1) is an immediate corollary. The method of proof of the asymptotic formula (1.2) was later generalized independently by Turin and Kubilius to give an upper bound for the left hand side where w(n) is replaced by an arbitrary additive function. The significance of the “loglog x” in (1.2) is that it is about CpsX w(p)p-1, where p runs over(More)
Hemodynamic and pulmonary gas exchange consequences of 20 percent intravenous fat emulsion infusion (3.0 +/- .3 mg/kg/min) were evaluated in 19 patients who demonstrated ARDS. Lipid infusion precipitated a significant reduction in PaO2/FIO2 from 241 +/- 50 to 184 +/- 41 (mean +/- SD) and increased MPAP from 26.0 +/- 5.1 to 31.8 +/- 4.8 mm Hg, pulmonary(More)
Cardiopulmonary effects of 500 ml of 20% iv fat emulsion (Intralipid) infusion in two groups of patients who required mechanical ventilation were evaluated in our Critical Care Center. Group 1 included ten patients void of signs or symptoms of sepsis. Group 2 consisted of ten patients exhibiting clinical and laboratory signs and symptoms of sepsis. Data(More)
The heating capabilities of a water bath blood/fluid warmer, Hotline, have proven superior to those of other devices. The dry heat warmer Ranger has not previously been compared with the Hotline. We evaluated these devices in terms of flow rates and efficacy of warming. We delivered room temperature (21 degrees C) saline and 10 degrees C packed red blood(More)
BACKGROUND A directionally changing shock electrical vector could facilitate defibrillation by depolarizing myocytes with different orientations vis-à-vis the shock field. Such a changing vector can be achieved by a new waveform for transthoracic defibrillation: overlapping sequential pulses. Our purpose was to evaluate this waveform. METHODS AND RESULTS(More)
STUDY OBJECTIVE This two-part study was designed to determine the effect of supplemental oxygen on the detection of hypoventilation, evidenced by a decline in oxygen saturation (Spo(2)) with pulse oximetry. DESIGN Phase 1 was a prospective, patient-controlled, clinical trial. Phase 2 was a prospective, randomized, clinical trial. SETTING Phase 1 took(More)
Some features of 22 cases of carcinoid tumour are described. The histology of the tumour was the criterion for inclusion in the series. The histology was reviewed by an observer unfamiliar with the clinical features. Six patients, each with an entirely endobronchial tumour of typical histology treated satisfactorily by surgery, are excluded from further(More)
OBJECTIVE Cardiac outputs were determined with continuous thermodilution, bolus thermodilution, and the Fick method during pharmacologically varied hemodynamics. DESIGN Prospective comparison of techniques. SETTING University animal laboratory. PARTICIPANTS Swine. INTERVENTIONS Swine were anesthetized, tracheally intubated, and instrumented to(More)
A national survey of hospital-based respiratory care departments was conducted to quantitate the use of various techniques and criteria employed to facilitate weaning of patients from mechanical ventilatory support. Responses were partitioned into private, nonprivate and university/university-affiliated institutions with further subdivision into bed-size(More)
Cardiovascular and pulmonary effects following the administration of 0.3 mg/kg of etomidate were studied in patients with documented cardiac disease. The only significant change was a slight elevation (2 torr) in arterial carbon dioxide tension.
