The tidal volume fix and more…

The Solution First Programming Process—or “How Quick Fix is much more than a quick fix”!

Learning to program is hard and one major obstacle for students is getting to grips with the programming process itself: What do I do now, what are the next steps, and what end result do I want to achieve? Further complications arise as many, even simple, designs require quite a lot of code to be written that are just “stepping stones” on the path to a solution. Thus, instead of “writing the co...

Intraoperative low-tidal-volume ventilation.

Low Tidal Volume Ventilation: Trust but Verify.

Despite affecting an estimated 4 –7% of patients in the ICU and having a high mortality rate, there are currently a limited number of therapeutic options to treat patients with ARDS.1,2 ARMA, the landmark ARDSnet trial in 2000, established the concept of lungprotective ventilation, where subjects with ARDS receiving mechanical ventilation were randomly assigned to a set tidal volume (VT) of eit...

Correlation properties of tidal volume and end-tidal O2 and CO2 concentrations in healthy infants.

We investigated whether breath-to-breath fluctuations in tidal volume (VT) and end-tidal O2 and CO2 exhibit long-range correlations and whether parameters describing the correlations can be used as noninvasive descriptors of control of breathing. We measured VT and end-tidal O2 and CO2 over n = 352 +/- 104 breaths in 26 term, healthy, unsedated infants (mean age +/- SD: 36 +/- 6 days) and calcu...

Low-tidal-volume ventilation in the acute respiratory distress syndrome.

Copyright © 2007 Massachusetts Medical Society. A 55-year-old man who is 178 cm tall and weighs 95 kg is hospitalized with community-acquired pneumonia and progressively severe dyspnea. His arterial oxygen saturation while breathing 100% oxygen through a face mask is 76%; a chest radiograph shows diffuse alveolar infiltrates with air bronchograms. He is intubated and receives mechanical ventila...
