Admission oxygenation (Pao2, breathing room air) for all patients with microbiologically confirmed PCP and for those admitted to the ICU with microbiologically confirmed PCP
| Study period/patient group | Admission Pao2 (kPa, breathing room air)* |
|---|---|
| Values are median (range). | |
| *In a comparison of patients presenting before mid 1996 and those presenting subsequently, Pao2 was lower in those admitted to the ICU (p = 0.003) and overall (p<0.001). | |
| 1990–1993 | |
| ICU PCP (n = 14) | 7.9 (3.9–13.1) |
| All PCP (n = 137) | 9.4 (3.9–13.2) |
| 1994–1997 | |
| ICU PCP (n = 28) | 7.7 (4.8–13.6) |
| All PCP (n = 148) | 9.4 (5.0–13.6) |
| 1998–2001 | |
| ICU PCP (n = 5) | 6.2 (4.0–10.1) |
| All PCP (n = 44) | 9.3 (4.0–13.2) |
| 2002–2005 | |
| ICU PCP (n = 13) | 6.9 (5.2–8.7) |
| All PCP (n = 38) | 7.9 (5.2–11.4) |
