A comparison of the results of point-prevalence epidemiological studies on mechanical ventilation in ICUs.
| International study 2000 [4] | Scandinavian study 2002 [5] | Polish study 2010 | |
|---|---|---|---|
| The number of ventilated patients (% of total ICU patients) | 1638 (36%) | 108 (47%) | 327 (74%) |
| Age [years]* | 61 | 66 | 63 |
| Gender (% men) | 60 | 69 | 63 |
| Indications for ventilation: (%) | |||
| ARF | 66 | 73 | 40 |
| Coma | 15 | 15 | 40 |
| COPD | 13 | 8 | 15 |
| Neuromuscular disease | 5 | 4 | 5 |
| Mechanical ventilation modes: | |||
| Tidal volume (ml/kg) * | 9 | 7 | 8 |
| Peak inspiratory pressure (cmH2O) * | 18 | 22 | 21 |
| Respiratory rate (breath/min) * | 16 | 17 | 13 |

Median value.
ARF – acute respiratory failure; COPD – chronic obstructive pulmonary disease; PEEP – positive end-expiratory pressure.
