TABLE 5.

Advantages and Disadvantages of PS Mode

Pressure Supported Ventilation
Advantages Disadvantages
1. The patient can control the depth, length, and flow of each breath
2. Allows flexibility in ventilator support
3. Improves synchrony and diaphragmatic work		 • Excessive level of support can result in:
 1. Respiratory alkalosis
 2. Hyperinflation
 3. Ineffective triggering
 4. Apneic spells
• Suboptimal support can result in:
 1. Diaphragmatic fatigue
 2. Respiratory acidosis

PS = pressure support.
