Adaptive servo-ventilation (ASV) therapy requires optimal pressure settings for heart failure patients. A PEEP ramp test with heart rate variability analysis can help identify these settings, potentially improving prognosis.
Area of Science:
- Cardiology
- Respiratory Medicine
- Medical Technology
Background:
- Adaptive servo-ventilation (ASV) is a non-invasive positive pressure ventilation for heart failure (HF) refractory to medical therapy.
- Higher ASV pressure settings may negatively impact patient prognosis.
- Optimal pressure settings for ASV therapy require identification.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Mechanical Ventilation II: Invasive Ventilation
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...
