Study Notes
Blocked Endotracheal Tube
- High-pressure alarm on ventilator indicates a blocked endotracheal tube.
- Nursing actions include suctioning secretions or inserting an oral airway to prevent biting.
Mechanical Ventilation
- Increased intrathoracic pressure is a result of mechanical ventilation.
- Positive end-expiratory pressure (PEEP) increases intrathoracic pressure.
- Increased intrathoracic pressure can decrease blood return to the heart, leading to decreased cardiac output and hypotension.
- Decreased cardiac output can trigger the renin-angiotensin-aldosterone system, potentially causing fluid retention and reduced urine output.
- Nursing actions include monitoring intake, output, weight, and hydration.
Client Education
- Advise clients to avoid the Valsalva maneuver (straining during bowel movements) as it increases intrathoracic pressure.
Barotrauma
- Positive-pressure ventilation can damage the lungs, causing complications like pneumothorax and subcutaneous emphysema.
Nursing Actions (Barotrauma)
- Monitor oxygenation status, blood gases, electrolytes, and chest x-ray.
- Assess for subcutaneous emphysema (identifiable by crackles or air movement under the skin).
- Monitor the ventilator's high-pressure alarm, as it can signal a pneumothorax.

Description
This quiz focuses on the critical nursing actions and considerations related to mechanical ventilation. Topics include managing blocked endotracheal tubes, understanding the effects of intrathoracic pressure, and client education to avoid complications. It's essential for nursing students and healthcare professionals to be well-versed in these areas.
