Permissive hypercapnia during mechanical ventilation in adults
2024年11月20日 · Ventilatory strategies that aim to reduce the risks of mechanical ventilation (eg, low tidal volume ventilation) may result in hypercapnia. Acceptance of the hypercapnia and continuation of the ventilation strategy is called permissive hypercapnia.
Respiratory acidosis (hypercapnia) and respiratory alkalosis ...
2024年7月20日 · Permissive hypercapnia involves an intentional strategy of allowing the pCO2 to increase during mechanical ventilation (with a goal of avoiding barotrauma). The limits of safe hypercapnia are unclear. Specifically, there is no pCO2 level above which obvious harm is noted.
Permissive hypercapnia - an overview | ScienceDirect Topics
Permissive hypercapnia (PHC) is a ventilatory strategy in which high levels of carbon dioxide (CO2) are tolerated as to avoid high tidal volumes, lung over-distention and ventilator induced lung injury.
Permissive hypercapnia for severe acute respiratory distress …
Permissive hypercapnia is a ventilation strategy to allow for an unphysiologically high partial pressure of carbon dioxide (PCO 2) to permit lung protective ventilation with low tidal volumes.
Permissive hypercapnia - Wikipedia
Permissive hypercapnia is hypercapnia (i.e. high concentration of carbon dioxide in blood) in respiratory insufficient patients in which oxygenation has become so difficult that the optimal mode of mechanical ventilation (with oxygenation in mind) is …
Permissive hypercapnia - PubMed
The aim of permissive hypercapnia is to minimize lung damage during mechanical ventilation; its limitation is the resulting hypoventilation and carbon dioxide (CO2) retention. In this article we discuss the rationale, physiologic implications, and implementation of permissive hypercapnia.
Permissive hypercapnia: Is there any upper limit? - PMC
In current practice, mean maximum PaCO 2 and pH associated with permissive hypercapnia are around 67 mmHg and 7.2, respectively, and are reported to be well tolerated as long as tissue perfusion and oxygenation are preserved and there are no contraindications.[6,7,8]
Permissive hypercapnia: what to remember - PubMed
This review will present data from recent studies relating to hypercapnia, focusing on issues that are of importance to anesthesiologists caring for the surgical and/or critically ill patient.
Bench-to-bedside review: Permissive hypercapnia - Critical Care
2004年8月5日 · This article reviews the current clinical status of permissive hypercapnia, discusses insights gained to date from basic scientific studies of hypercapnia and acidosis, and considers the potential clinical implications of these findings for the …

2024年7月5日 · Protective lung ventilation is the current standard of care for mechanical ventilation. It is synonymous with low tidal volume ventilation (4-8 mL/kg) and often includes permissive hypercapnia
