Consultation services were available for most medical and surgical specialties.The weaning process involved daily targets of either increasing periods of spontaneous breathing or a gradual reduction in pressure support. Other aspects of RCC care included identification of reversible causes of weaning failure, limited use of sedatives, restoration of normal selleck chem inhibitor sleep/wake cycles, attention to nutrition, pulmonary rehabilitation (including respiratory muscle training), and attempts to improve patient autonomy through methods such as establishing speech and self-feeding. Discharge planning was managed by nurse or social-work case managers. Hemodialysis was available in the RCC as required.

Variables measuredThe following variables were recorded for all study patients within 24 hours of admission: demographics, previous ICU type (medical or surgical; MICU or SICU), cause leading to PMV, duration of ICU and RCC stay, days on MV before RCC admission, total days on MV, day of tracheostomy after RCC admission (if the procedure was performed), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, serum albumin, blood urea nitrogen (BUN) level, and blood gas data. “Total mechanical ventilation days” was defined as the time from initiation of MV to the time when weaning was successful or attempts were ceased. “Length of (hospital) stay” was defined as the time from ICU admission to the end of hospital care. The highest modified Glasgow Coma Scale scores (GCS: verbal score as one) were also obtained by nurses within the first 24 hours of admission.

Rapid shallow breath indices Dacomitinib (RSBIs), arterial oxygen pressure/fraction of inspiratory oxygen (PaO2/FIO2), and maximal inspiratory negative pressure (PImax) were also measured during spontaneous breathing. PImax values were determined as the mean of three measurements by using a Wright spirometer. PaO2/FIO2 was assessed within the first week of RCC admission. RCC and in-hospital mortality were calculated. RCC mortality was determined as the number of patients who died in the RCC divided by the total number of patients admitted to the RCC. In-hospital mortality was determined as the number of patients who died either at the RCC or before discharge, divided by the total number of patients admitted to the RCC. The numbers of comorbidities also were assessed [5,6].
