| Title | Ventilator Monitoring Chart Extraction |
| Description | One settings panel per reading rather than four loose Observations, because a ventilator setting only means something beside the others: a peak inspiratory pressure of 30 is unremarkable at a PEEP of 5 and alarming at a PEEP of 15. The changes column is kept as a note on the panel -- a chart that records the settings but not the decisions behind them is a chart nobody can review afterwards. |
