Perceived responsibility for mechanical ventilation and weaning decisions in intensive care units in the Kingdom of Saudi Arabia.

The key decision-making was implemented mainly by physicians and respiratory therapists in collaboration. Nurses had limited involvement. Physician directors perceived higher autonomy and influence in ventilatory and weaning decision-making than respiratory therapist managers and nurse managers. A critical care unit's capacity to deliver effective and safe patient care may be improved by increasing nurses' participation and acknowledging the role of respiratory therapists in clinical decision-making regarding mechanical ventilation and weaning.
