Troubleshooting Changes in Vital Signs
| Question | Answer |
|---|---|
| Hypotension | Decreased venous return (caused by positive pressure) Evaluate fluid balance and possible need for filling of vascular bed |
| Hypertension | Anxiety response to decreased PaO2, decreased PaCO2 Reassure, alleviate fear Check patient-ventilator system; If not easily corrected obtain and evaluate ABG value |
| Respiratory swing of blood pressure | Decreased venous return (caused by positive pressure) systolic/diastolic pressures indicate inadequate perfusion, evaluate fluid balance; consider filling vascular bed |
| New arrhythmias | Anxiety Decreased PaO2 Decreased PaCO2 Increased PaCO2 Decreased venous return Reassure, alleviate fear |
| Large swings in CVP or PCWP | Decreased venous return Check other hemodynamics parameters for adequacy of perfusion |
| Decreased urinary output | Decreased renal perfusion Increased ADH Evaluate other hemodynamics parameters for adequacy of perfusion |
| Fever | infection Atelectasis Increased metabolic rate caused by fighting the ventilator Overheated humidifier Treat infection/review precautions Check for mucous plugs, ET position Check sensitivity and patient triggering effort settings Check temp |
| Changes in respiratory rate | Altered settings Change in metabolic needs Anxiety Sleep Check patient-ventilator settings Evaluate patient's metabolic rate Reassure, alleviate fears Normal observation |
| Accessory muscle use/paradoxical breathing | Increased work of breathing Patient-ventilator dyssynchrony auto-PEEP Increase support level Provide pressure support ventilation Increase insp flow or sensitivity Eliminate auto-PEEP |
