Shorter subjects (<175cm) were a specific risk group with an increased risk of not receiving lung protective ventilation (OR 6.6 95%CI 1.2-35.4 p = 0.02), while taller subjects had a smaller risk of being exposed to inadequately high tidal volumes (OR 0.15 95%CI 0.02-0.8 p = 0.02). 526 estimation-based tidal volumes (51.1%) did not provide lung-protective ventilation. When estimates of patients´ heights are used as a reference for tidal-volume definition, patients are exposed to mean tidal volumes of 6.5 ± 0.4 ml/kg/PBW. ![]() The majority of the estimates were imprecise and resulting data comprised taller body heights, higher PBW and higher tidal volumes (all p≤0.01). Finally, estimates and measurements were compared.ġ033 estimations were undertaken by 153 medical professionals. The patients' true heights were measured and the true PBW with a corresponding tidal volume was calculated. All medical professionals calculated the PBW and a corresponding tidal volume with 6 ml/kg/PBW on the basis of their visual estimation. In this prospective observational study, 28 mechanically ventilated patients had their heights visually estimated by 20 nurses and 20 physicians. We aimed to determine if the common practice of estimating visual height to define tidal volume reduces the possibility of receiving lung-protective ventilation. However, it is a common practice to visually estimate the body height of mechanically ventilated patients and use these estimates as a reference size for ventilator settings. ![]() Hence, an exact height is necessary to provide optimal mechanical ventilation. Lung-protective ventilation with tidal volumes of 6 mL/kg predicted body weight (PBW, calculated on the basis of a patient's sex and height), is part of current recommended ventilation strategy. Acute lung injury is a life threatening condition often requiring mechanical ventilation.
