Characteristics of patients who developed pneumothorax with NPPV therapy for OSA.
| Case | Age (years) | Sex | NPPV indication | Underlying lung pathology | NPPV type | NPPV pressure settings |
|---|---|---|---|---|---|---|
| Current case—Rajdev et al. | 66 | F | Obstructive sleep apnea | Right-sided pleural effusion and diaphragmatic hernia | CPAP with nasal mask | (i) Auto-CPAP pressure-4-20 cm H2O |
| Langner et al. [6] | 68 | NA | Obstructive sleep apnea | None | CPAP | (i) Initial therapy pressure-9 cm H2O (ii) Pressure later increased-13 cm H2O |
| Herrejón Silvestre et al. [8] | 67 | M | Obstructive sleep apnea | Pan acinar emphysema | BPAP with nasal mask | (i) Inspiratory pressure-10 cm H2O (ii) Expiratory pressure-5 cm H2O |
| Mao et al. [20] | 64 | M | Obstructive sleep apnea | None | PAP (ASV) | (i) Pressure support-5-10 cm H2O (ii) EPAP-15 cm H2O |
| Chicote Álvarez et al. [21] | 72 | NA | Obstructive sleep apnea | NA | CPAP | (i) NA |
ASV: adaptive support ventilation; BPAP: bilevel positive airway pressure; CPAP continuous positive airway pressure; EPAP: expiratory positive airway pressure; F: female; H2O: water; M: male; NA: not available; NPPV: noninvasive positive pressure ventilation; OSA: obstructive sleep apnea.
