Mechanical Ventilation and ARDS Concepts

These flashcards cover key concepts regarding mechanical ventilation, ARDS, and the associated terminology and measurements necessary for understanding the topics.

What does PEEP help with in mechanical ventilation?

PEEP helps with oxygenation and stabilizes alveoli in conditions of high lung compliance.

What is the significance of compliance in mechanical ventilation?

Compliance measures how easily the lungs can expand; higher compliance means less effort is needed for ventilation.

Which mode provides the patient with the most work in mechanical ventilation?

AC/VC mode gives the patient the most work.

What is the function of CPAP in mechanical ventilation?

CPAP allows the patient to breathe spontaneously while providing support.

What is the normal respiratory rate (RR) range for ventilated patients?

The normal respiratory rate for ventilated patients is between 12 to 20 breaths per minute.

What does a high resistance in the airway mean for tidal volume?

If airway resistance is high, it may require more effort or pressure to maintain adequate tidal volume.

What happens during positive pressure ventilation?

Positive pressure ventilation pushes air into the lungs.

What are spontaneous breaths in mechanical ventilation?

Spontaneous breaths are initiated by the patient without mechanical assistance.

Why should untreated pneumothorax not use a chest tube?

Untreated pneumothorax poses a risk and requires careful management; chest tubes should not be used without proper assessment.

What is the recommended tidal volume (VT) range for mechanical ventilation?

The recommended tidal volume range is 4 to 8 mL/kg.
