The nurse has just attended a conference on caring for the client receiving positive pressure ventilation (PPV). Which statement by the nurse would indicate a correct understanding of the conference?
The nurse has just attended a conference on caring for the client receiving positive pressure ventilation (PPV). Which statement by the nurse would indicate a correct understanding of the conference?
A. "Positive pressure mechanical ventilation helps improve oxygenation and supports breathing by delivering air into the lungs at an increased pressure during inspiration."
[77%]
B. "Clients receiving positive pressure mechanical ventilation can breathe spontaneously without any assistance from the ventilator machine."
[6%]
C. "Positive pressure mechanical ventilation is used primarily for clients with a normal respiratory drive to enhance their natural breathing pattern."
[7%]
D. "The rate and depth of positive pressure mechanical ventilation are solely determined by the client's effort and respiratory rate."

Explanation
Choice A is correct. This statement accurately reflects the purpose and mechanism of positive pressure mechanical ventilation. This elevated pressure helps inflate the alveoli, enhancing oxygenation and supporting breathing for clients who are unable to breathe adequately on their own due to compromised lung function.
Choice B is incorrect. Positive pressure ventilation is used when clients are unable to breathe sufficiently on their own due to various conditions. Including but not limited to Acute Respiratory Distress Syndrome (ARDS), Status Asthmaticus, and Central Nervous System Depression (e.g., Stroke, Brain Injury).
Choice C is incorrect. Clients who require positive pressure ventilation often have impaired respiratory drive. Positive pressure ventilation takes over the work of breathing to support the client's respiratory efforts and ensure sufficient oxygenation and carbon dioxide removal.
Choice D is incorrect. With positive pressure mechanical ventilation, the rate and depth of breaths are determined by the ventilator settings, not the client's effort or respiratory rate.

Additional Info
✓ The complications associated with positive pressure ventilation are many and can be quite serious. Including but not limited to
- Barotrauma
- Ventilator-associated Lung Injury
- Hemodynamic Effects
✓ Familiarize yourself with the ventilator alarms and their meanings. Respond promptly to any alarms and troubleshoot issues to prevent interruptions in ventilation and ensure client safety.
✓ Work closely with the multidisciplinary team, including respiratory therapists, physicians, and clinical pharmacists, to ensure coordinated and comprehensive care for clients on mechanical ventilation.
