1 Interactions among clinician, patient, and ventilator.
Interactions among clinician, patient, and ventilator. The clinician is key in the interaction. The clinician can improve patient-ventilator interaction, for instance, by administering a bronchodilator to decrease intrinsic PEEP, or by applying appropriate ventilator settings (eg, applied PEEP, VT, flow) or specific ventilatory modes (eg, proportional assist ventilation [PAV], or neurally adjusted ventilatory assist [NAVA]). On the other hand, the clinician can worsen the interaction, for example, by administering heavy sedation. A bidirectional interaction between patient and ventilator occurs with automation (eg, with SmartCare, a pressure-support mode that uses artificial intelligence for weaning).
