Characteristics of smokers with OPD-CB and low transcutaneous oxygen during exacerbations
| Severity of OPD-CB | Inclusion (n=18)
|
Exacerbation (n= 18)
|
||||
|---|---|---|---|---|---|---|
| Transcutaneous oxygen saturation (%) | Inhaled glucocorticoids (yes/no) | Respiration rate (per minute) | PaO2 (kPa) | Respiration rate (per minute) | Hospitalization (yes/no) | |
| Mild (n=10) | 95 (94–98) | 6/4 | 18 (15–22) | 8.9 (7.2–10.4) | 21 (18–22) | 2/8 |
| Severe (n=8) | 93 (92–95) | 6/2 | 20 (16–24) | 7.8 (7.3–9.8) | 20 (16–26) | 1/7 |
Notes: All individuals in the table had transcutaneous oxygen saturation <94% but none required mechanical ventilation during exacerbations; mild, OPD-CB corresponding to GOLD stage I and II; severe, OPD-CB corresponding to GOLD stage III–IV; the data are presented as the median and range (n=8–10).
