MYOCARDIAL ISCHEMIA, ARRHYTHMIA
The present study was designed as an open-label, randomized, crossover, two-center
clinical trial to assess the impact of different vertical positions on lung aeration
in hospitalized ICU patients receiving IMV. Patients were enrolled from January to
July 2020 and followed from the medical-surgical ICUs of All consecutive subjects ≥ 18 years of age admitted to the ICU and ventilated
for ≥ ¬¬24 hours and ≤ 7 days, without an extubation plan on the day
of the study protocols, were eligible for inclusion. The exclusion criteria were as
follows: a noradrenaline level > 0.2mcg/kg/minute; a > 50% increase in the
dose of noradrenaline (as long as it exceeded 0.1 mcg/kg/minute) within 2 hours
prior to enrollment; a sodium nitroprusside level > 1 mcg/kg/minute; a heart rate
< 40 or > 130bpm; active myocardial ischemia; a systolic blood pressure >
200mmHg or a mean arterial blood pressure < 65 mmHg; arrhythmia; the presence of
an intra-aortic balloon counterpulsation; a fraction of inspired oxygen > 60%; a
positive end-expiratory pressure ≥ 10cmH
