BACKGROUND There are contradictory reports concerning hypercapnia as a predictor of a better outcome in COPD. This study examined the clinical implications of hypercapnea in COPD patients (M:F = 59:19) who required mechanical ventilation. METHODS The clinical parameters at the time of MICU admission, the total ventilation time, the APACHE II score and the pulmonary function testing were retro...

OBJECTIVES To characterize patients who received tracheostomies for airway compromise or were initiated on long-term ventilation for chronic respiratory failure in PICUs and to examine variation in the incidence of initiation, patient characteristics, and modalities across sites. DESIGN Retrospective cross-sectional analysis. SETTINGS Seventy-three North American PICUs that participated in ...

during the primary survey life-threatening or limb-threatening conditions are identified and management is instituted simultaneously. priorities for the care of adult, pediatrics & pregnancy women are all the same. you should do rapid sequential way to assess the patients in 10 seconds treat as you find life threatening condition and repeat if at any time unstable vital signs should be repeated...

background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...

BACKGROUND Hypoxemia is common during one-lung ventilation (OLV). Atelectasis contributes to the problem. Biologically variable ventilation (BVV), using microprocessors to reinstitute physiologic variability to respiratory rate and tidal volume, has been shown to be advantageous over conventional monotonous control mode ventilation (CMV) in improving oxygenation during the period of lung reinfl...

Airway pressure-release ventilation (APRV) is a mechanical ventilation strategy that is usually time-triggered but can be patient-triggered, pressure-limited, and time-cycled. APRV provides 2 levels of airway pressure (P(high) and P(low)) during 2 time periods (T(high) and T(low)), both set by the clinician. APRV usually involves a long T(high) and a short T(low). APRV uses an active exhalation...

STUDY OBJECTIVE The validation of electrical impedance tomography (EIT) for measuring regional ventilation distribution by comparing it with single photon emission CT (SPECT) scanning. DESIGN Randomized, prospective animal study. SETTINGS Animal laboratories and nuclear medicine laboratories at a university hospital. PARTICIPANTS Twelve anesthetized and mechanically ventilated pigs. INT...

OBJECTIVE To evaluate the contemporary practice, outcomes, and costs related to mechanical ventilation among ICUs in China. DESIGN A prospective observational cohort study. SETTING Fourteen ICUs among 13 hospitals in Beijing, China. PATIENTS Seven hundred ninety-three patients who received at least 24 hours of mechanical ventilation within the first 48 hours of ICU stay. INTERVENTION No...

BACKGROUND The efficacy of protective ventilation in acute lung injury has validated its use in the operating room for patients undergoing thoracic surgery with one-lung ventilation (OLV). The purpose of this study was to investigate the effects of two different modes of ventilation using low tidal volumes: pressure controlled ventilation (PCV) vs. volume controlled ventilation (VCV) on oxygena...

OBJECTIVE To compare the effects of high-frequency oscillatory ventilation and conventional protective mechanical ventilation associated with the prone position on oxygenation, histology and pulmonary oxidative damage in an experimental model of acute lung injury. METHODS Forty-five rabbits with tracheostomy and vascular access were underwent mechanical ventilation. Acute lung injury was indu...
