What is the main goal of pressure support ventilation?

• A. To provide complete mechanical ventilation regardless of effort
• B. To enhance the patient's tidal volume while allowing spontaneous breathing
• C. To ensure total oxygen delivery without considering respiratory effort
• D. To minimize patient involvement in the respiratory process

Answer: (B)

The primary goal of pressure support ventilation is to enhance the patient's tidal volume while allowing for spontaneous breathing. This mode of ventilation is specifically designed to support patients who are capable of initiating their own breaths but may require assistance to achieve adequate ventilation. The pressure support delivered during inhalation helps to augment the volume of air the patient is able to take in, improving gas exchange without taking over the breathing function entirely. By providing this level of support, pressure support ventilation allows patients to maintain some degree of control over their breathing, which is important for comfort and can lead to better patient outcomes. This mode is particularly beneficial in situations where patients are recovering from respiratory distress or in conditions like chronic obstructive pulmonary disease (COPD), where spontaneous breathing may be compromised.
