Abstract

The intra-aortic balloon pump (IABP) is a device used to help the heart pump. During the IABP assistance, significant changes in arterial pressure waveform occur. The so-called pulse contour methods (PCMs) use proper algorithms to analyse the arterial pressure waveform and obtain the cardiac output (CO) [1]. As a consequence, changes in pressure waveform in patients on IABP may affect the reliability of different PCMs. The aim of this study was to investigated the reliability of a new PCM, the MostCare powered by the pressure recording analytical method (PRAM) (Vytech Health, Laboratoires Pharmaceutiques Vygon, Ecouen, France), by comparing its CO values (PRAM-CO) with those determined by bolus thermodilution (ThD-CO) during aortic counterpulsation.

Highlights

There is considerable uncertainty about the reproducibility of the various instruments used to measure dyspnea, their ability to reflect changes in symptoms, whether they accurately reflect the patient’s experience and if its evolution is similar between acute heart failure syndrome patients and nonacute heart failure syndrome patients
Results of this study show that early tracheostomy, if perioperative complications
We did not find significant differences in the arterial catheterrelated infection (ACRI) incidence per 1,000 arterial catheter days between radial and dorsalis pedis (OR = 1.5; 95% cardiac index (CI) = 0.24 to infinite; P = 0.73); and between radial and brachial access (OR = 1.2; 95% CI = 0.20 to infinite; P = 0.88)

Summary

Introduction

There is considerable uncertainty about the reproducibility of the various instruments used to measure dyspnea, their ability to reflect changes in symptoms, whether they accurately reflect the patient’s experience and if its evolution is similar between acute heart failure syndrome patients and nonacute heart failure syndrome patients. Conclusions Our data demonstrate that critically ill patients may be exposed to a higher FiO2 than that required to maintain adequate oxygenation These results highlight an area of ICU care that has received little study, with no published clinical trials examining the effect of FiO2 on outcome. Results Age, sex, the underlying disease and tumour stage (TNM classification), type of previous anticancer treatment, performance status, severity scores (APACHE II, Simplified Acute Physiology Score II, Sequential Organ Failure Assessment), ICU and hospital mortalities and hospital outcome at 3, 6 and 12 months were analysed. Clinical data of 277 post-transplantation patients admitted to the ICU were collected at admission and the SAPS 3 and APACHE II score calculated with respective estimated mortality rates.
