Which three breath types are available with positive pressure ventilation?

In positive pressure ventilation, the breath types available are crucial in determining how the patient receives mechanical support versus spontaneous breathing. The correct answer emphasizes three distinct breath types commonly used in mechanical ventilation settings: spontaneous, mandatory, and assisted.

Spontaneous breaths are those taken by the patient themselves, where they initiate the breath and the ventilator supports them in delivering the necessary pressure or volume. This type of breathing allows the patient to maintain control over their respiratory efforts, which can be beneficial for their overall comfort and independence.

Mandatory breaths are fully controlled by the ventilator, meaning that the machine determines every breath delivered, regardless of the patient's own effort. This is particularly useful in situations where the patient's own respiratory drive is insufficient or absent.

Assisted breaths occur when the patient initiates a breath, and the ventilator provides support to help with the delivery of volume or pressure. This type is particularly helpful for patients who need some assistance but can still initiate their own breathing effort.

These three types align well with the needs of patients in different clinical states, allowing for flexibility in management based on the patient’s respiratory drive and overall condition. Other answer choices do not accurately represent the common breath types used in positive pressure ventilation or include incorrect combinations of terms that do not present
