Riley, who has severe left-sided heart failure and cardiogenic shock, is being intubated. The provider orders 10 cm H_2O of Positive End-Expiratory Pressure (PEEP).
Why should the RN monitor the blood pressure especially closely after this setting is applied?
- PEEP stimulates the vagus nerve, causing sudden profound bradycardia, for this client.
- High PEEP levels increase the risk of developing metabolic alkalosis
- PEEP increases intrathoracic pressure, which can decrease venous return and BP
- PEEP causes systemic vasodilation through the release of nitric oxide.
