What is a key indication for initiating mechanical ventilation?

• A. Respiratory failure that cannot be resolved by other means.
• B. Patient preference for ventilation.
• C. Normal oxygen saturation levels.
• D. High alertness and responsiveness of the patient.

Answer: (A)

Initiating mechanical ventilation is primarily indicated in cases of respiratory failure that cannot be managed by other means. This decision is based on the patient's inability to maintain adequate gas exchange, which may be due to conditions such as severe acute respiratory distress syndrome, chronic obstructive pulmonary disease exacerbations, or neurological disorders affecting respiratory drive. When respiratory failure occurs, the patient's ability to ventilate effectively or to oxygenate adequately can be compromised. Mechanical ventilation provides essential support in these situations, allowing for controlled ventilation and ensuring that adequate oxygen levels are maintained, as well as facilitating the removal of carbon dioxide from the body. In contrast, other options—such as patient preference for ventilation, normal oxygen saturation levels, or high alertness and responsiveness—do not justify the need for mechanical ventilation. Preferences or stable physiological parameters indicate that a patient may not need such invasive intervention unless their condition deteriorates significantly.
