Final answer:
Statement 'c. SIMV is easy to apply' is NOT true regarding the use of IMV or SIMV in mechanical ventilation, as its application requires careful clinical setup and monitoring.
Step-by-step explanation:
Among the statements given regarding the use of intermittent mandatory ventilation (IMV) or synchronized intermittent mandatory ventilation (SIMV), the statement that is NOT true is: c. SIMV is easy to apply. While SIMV allows the patient to breathe spontaneously in between mechanical breaths and may help maintain ventilatory muscle strength, saying it is easy to apply is subjective and may not hold true in all clinical situations as it requires careful setup and patient monitoring.
Intensive care units use various modes of mechanical ventilation, including IMV and SIMV, to aid patients with compromised respiratory function. In SIMV mode, the ventilator synchronizes with the patient’s efforts and provides supportive breaths at set intervals, which can help preserve diaphragmatic function by allowing spontaneous breathing. Respiratory volumes and capacities like functional residual capacity (FRC) and total lung capacity (TLC) are important considerations in mechanical ventilation settings to optimize patient care.
The control of ventilation involves a complex mechanism that includes the rhythm and depth of breathing, as well as the combination of both voluntary and involuntary respiratory muscles. During mechanical ventilation, especially in SIMV mode, clinician expertise is imperative to properly match the machine support to the patient's specific respiratory needs.
