Tidal Volume-Dependent Activation of the Renin-Angiotensin System in Experimental Ventilator-Induced Lung Injury.
Ventilator-induced lung injury (VILI) is a major contributor to morbidity and mortality in critically ill patients. Mechanical damage to the lungs is potentially aggravated by the activation of the renin-angiotensin system (RAS). This article describes RAS activation profiles in VILI and discusses the effects of angiotensin (Ang) 1-7 supplementation or angiotensin-converting enzyme (ACE) inhibition with captopril as protective strategies. ⋯ VILI is accompanied by a strong activation of the RAS. Based on circulating Ang metabolite levels and tissue expression of RAS enzymes, classical ACE-dependent and alternative RAS cascades were activated in the HV T group, whereas classical RAS activation prevailed with VHV T ventilation. Ang 1-7 or captopril protected from VILI primarily by modifying the systemic RAS profile.

Communication with patients receiving mechanical ventilation in an intensive care unit can be challenging. Once a patient is tracheostomized, a speaking valve may enable restoration of verbal communication. To date, no data are available on the effect of speaking valves on communication success in intensive care units. ⋯ A speaking valve should be considered for patients with a tracheostomy as soon as possible to improve their communication success.

Respiratory rate (RR) alarms alert clinicians to a change in a patient's condition. However, RR alarms are common occurrences. To date, no study has examined RR alarm types and associated patient characteristics, which could guide alarm management strategies. ⋯ High parameter limit RR alarms were most frequent. Factors associated with RR alarms included monitoring time, ICU type, male sex, and mechanical ventilation. Although these factors are not modifiable, these data could be used to guide management strategies.
