Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia ; a rise in arterial carbon dioxide levels is called hypercapnia .
Permissive hypercapnia, a ventilatory strategy for acute respiratory failure in which the lungs are ventilated with a low inspiratory volume and pressure, has been accepted progressively in critical care for adult, pediatric, and neonatal patients requiring mechanical ventilation and is one of the central components of current protective ...
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [ 1 ]
In the past, the drug doxapram (a respiratory stimulant), was used for hypercapnia in acute exacerbation of chronic obstructive pulmonary disease but there is little evidence to support its use compared to NIV, [24] and it does not feature in recent professional guidelines. [12] Very severe respiratory failure, in which hypercapnia may also be ...
The Conventional Ventilatory Support vs. Extracorporeal Membrane Oxygenation for Severe Adult Respiratory Failure (CESAR) Trial was a UK-based multicenter RCT aiming to evaluate the safety, efficacy and cost effectiveness of ECMO compared to conventional mechanical ventilation in adults with severe but reversible respiratory failure. [63]
An acute exacerbation of chronic obstructive pulmonary disease, or acute exacerbations of chronic bronchitis (AECB), is a sudden worsening of chronic obstructive pulmonary disease (COPD) symptoms including shortness of breath, quantity and color of phlegm that typically lasts for several days.
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
With acute upper airway obstruction, respiratory distress can rapidly lead to respiratory failure without appropriate management [2] necessitating urgent and comprehensive assessment of ABCs (airway, breathing, and circulation). [1] Imaging studies, including x-rays and CT scans, can aid diagnosis and quickly assess the obstruction's extent. [2]
