Management of the acutely ill patient with PH should include careful evaluation for secondary causes of decompensation (such as a low-grade line infection or pulmonary thromboembolism).
The management approach can be broadly divided into two stages: immediate ED management and subsequent or specialist management. Immediate ED management options are presented below.
| Problem | Intervension(s) required |
| Hypoxaemia | Supplemental oxygen |
| Arrhythmias |
|
| Volume overload |
|
| Acute right heart failure |
|
| Cardiac arrest | Advanced life support resuscitation while searching for underlying precipitant |
| Technical intravenous catheter and pump problems | Prompt restoration of intravenous therapy |
| Catheter-related infection |
|
| Bleeding in warfarinised PH patients |
