A patient diagnosed with ARDS is being mechanically ventilated with 12 cm of PEEP. On assessment, the nurse notes deterioration of vital signs and absent breath sounds in the right lung field
The most likely cause for this finding may be a (an) 1. deterioration of the disease.
2. pneumothorax.
3. decreased cardiac output.
4. obstructed endotracheal tube.
2
Rationale: A complication of PEEP may be a pneumothorax as a result of overdistention of the alveoli. If deterioration of the disease were the cause, both lung sounds would be decreased equally. Decreased cardiac output would affect vital signs but not breath sounds. An obstructed endotracheal tube would affect both lung fields.
