Assessment of Ventilation
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.

Mechanical Ventilation II: Invasive Ventilation

941
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
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...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Mechanical Ventilation I: Indication and Settings

3.4K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Ventilatory Modes01:14

Ventilatory Modes

1.9K
Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
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...

Area of Science:

  • Critical Care Medicine
  • Respiratory Therapy
  • Clinical Trials

Background:

  • Intrahospital transport of critically ill, mechanically ventilated patients poses significant physiological risks.
  • Adaptive Minute Ventilation (AMV) is a closed-loop system designed to automatically maintain target minute ventilation.
  • The efficacy and safety of AMV during intrahospital transport remain unevaluated.

Purpose of the Study:

  • To assess the safety and efficacy of AMV compared to conventional ventilation strategies during intrahospital transport.
  • To evaluate AMV's performance in maintaining target minute ventilation in a transport setting.
  • To address an evidence gap in mechanical ventilation strategies for critically ill patients during transport.

Main Methods:

  • A single-centre, open-label, randomized controlled non-inferiority trial involving 50 adult patients.
  • Patients were randomized (1:1) to receive either AMV or their pre-transport ventilation mode.
  • Primary endpoint: change in arterial carbon dioxide pressure (PaCO₂) from pre-transport to post-transport.

Main Results:

  • The primary outcome will be the change in PaCO₂.
  • Secondary outcomes include changes in oxygenation index (PaO₂/FiO₂), peak airway pressure, dynamic compliance, and rapid shallow breathing index.
  • Intention-to-treat and per-protocol analyses will be performed, with missing data handled by multiple imputation.

Conclusions:

  • This is the first randomized study to evaluate AMV during intrahospital transport of critically ill patients.
  • The study aims to provide robust evidence on AMV's safety and effectiveness as a transport ventilation alternative.
  • Findings may inform clinical practice and improve patient care during critical illness transport.
