Final answer:
Pure time-triggered ventilation is equivalent to intermittent mandatory ventilation (IMV), a form of mechanical ventilation providing a set number of breaths at a specified volume and rate. Unlike assist-control ventilation, IMV does not synchronize with the patient's own breathing efforts.
Step-by-step explanation:
Pure time-triggered ventilation is the same as intermittent mandatory ventilation (IMV). This type of mechanical ventilation provides a set number of breaths to a patient at a specified tidal volume and rate, regardless of the patient's own breathing efforts. During IMV, the patient can breathe spontaneously between machine-delivered breaths. As a result, the ventilation is not synchronized with the patient's effort, which distinguishes it from assist-control ventilation where each patient-initiated breath is assisted by the machine.
It's important to differentiate between different types of respiration:
- External respiration refers to the gas exchange between the air in the alveoli and the blood in the pulmonary capillaries.
- Interpulmonary respiration is not a commonly used term but could be assumed to be synonymous with external respiration.
- Internal respiration refers to the gas exchange between systemic blood and tissues.
- Pulmonary ventilation is the physical movement of air in and out of the lungs.
Distinguishing these terms is essential for understanding respiratory physiology and the various types of mechanical ventilation used in clinical practice.
