Mechanical ventilators availability survey in Thai ICUs (ICU-RESOURCE I Study)
Summary
Mechanical ventilators (MV) are widely available in Thai ICUs, with electrically dependent models dominating. Bennette and Hamilton are the most common brands, and advanced models are more prevalent in academic settings.
Area of Science:
- Critical Care Medicine
- Medical Engineering
- Health Services Research
Background:
- Mechanical ventilation is crucial in intensive care units (ICUs).
- Rapid advancements in ventilator technology are occurring globally.
- Data on mechanical ventilator (MV) availability in Thai ICUs were previously limited.
Purpose of the Study:
- To describe the supply and availability of mechanical ventilators in Thai ICUs.
- To review key characteristics related to MV availability.
- To assess the distribution of different MV types and brands across Thai ICUs.
Main Methods:
- Utilized the ICU RESOURCE I study database (Mechanical ventilator part).
- Recorded hospital types, MV brands, and models.
- Employed statistical analysis with a p-value < 0.05 for significance.
Main Results:
- A total of 2,098 MVs were analyzed.
- Electrically independent MVs (Bird's Mark) constituted 21.35%, while electrically dependent MVs (eMVs) comprised 78.65%.
- Bennette and Hamilton were the most prevalent eMV brands (approx. 50%), followed by Event, Newport, CareFusion/Bird, Drager, and Servo.
- Advanced MVs (EvitaXL, Hamilton G5, Servo-I, Epi-NAVA) and adult High-Frequency Oscillatory Ventilation (HFOV) were more common in academic ICUs.
Conclusions:
- Bird Mark ventilators represent a significant proportion of MVs in Thai ICUs.
- Bennette and Hamilton are the most frequently available MV brands.
- Academic ICUs demonstrate greater availability of advanced MV models.

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...

4.2K
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...

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.

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.

2.3K
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...

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
2.8K
Respiratory Depth
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:
