Background:
Successful liberation from prolonged mechanical ventilation (PMV) is a challenging phenomenon. Whereas many physiological factors have been linked to successful PMV liberation, the psychosocial components are not well delineated.
Objectives:
This article serves to describe the experience of patients who survived PMV and to identify salient factors that contributed to successful liberation.
Methods:
A phenomenological approach was used to explore the lived experience of seven PMV survivors.
Results:
Six mutually exclusive themes emerged from the participants' descriptions to create a structural description of the lived experience.
Conclusions:
Survivors credited their own self-determination and the expertise and care of health care professionals with their ability to be successfully liberated from prolonged mechanical ventilation. Although surviving PMV was described as frightening and traumatic, comfort and resolve were derived from family members, religion, prayer, and angelic encounters. These findings are useful in providing direction for critical care clinical practice and future research.

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...

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...

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...
