Question

After assisting with bronchoalveolar lavage and lung biopsy on a mechanically ventilated patient, the respiratory therapist notes the activation of a high pressure alarm. Peak inspiratory pressure has increased from 32 cm H₂O before the procedure to 45 cm H₂O after the procedure. Possible causes for the increased pressure include ___________.

1) bronchospasm
2) pneumothorax
3) pulmonary hemorrhage

Answer 1

Possible causes for the increased pressure include bronchospasm, pneumothorax, and pulmonary hemorrhage.

Step-by-step explanation:

The possible causes for the increased pressure after the procedure include bronchospasm, pneumothorax, and pulmonary hemorrhage.

1) Bronchospasm: Bronchospasm is the constriction of the airway muscles, leading to narrowing of the airways. This can increase airway resistance and cause an increase in peak inspiratory pressure.

2) Pneumothorax: Pneumothorax is the presence of air in the pleural cavity, causing the lung to collapse. This can lead to increased pressure in the lung and an increase in peak inspiratory pressure.

3) Pulmonary hemorrhage: Pulmonary hemorrhage is the bleeding in the lungs, which can cause obstruction in the airways and increased resistance to airflow, resulting in increased peak inspiratory pressure.
