Abstract:
Long-term mechanical ventilation (LTMV) is used to support growing numbers of children and adults who develop chronic respiratory failure. The purpose of this hermeneutic phenomenological study was to explore the subjective meaning of the experience of transition from spontaneous breathing to reliance on LTMV. In-depth, audiorecorded interviews of 11 ventilated individuals living in a western Canadian province were transcribed and analyzed. The transition journey was revealed to be a time of psychological, physical, and spiritual challenge. "Sustaining self " was revealed as the essence of ventilator users' transition experience. Findings underscore the complex nature of transition to technological reliance, illuminating the need for increased health professional knowledge and understanding of the symptom experience and management options for individuals living with chronic respiratory failure. Strategies to support individuals' sense of self as they journey to a life reliant on LTMV are required.

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...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

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:
Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...
