Summary
Frame rate is crucial for recognizing agonal respiration in ambulances. Higher frame rates improve telemedicine accuracy and reduce delays, even with limited mobile network quality.
Area of Science:
- Emergency Medicine
- Telemedicine
- Mobile Network Technology
Background:
- Mobile network quality in ambulances is often inconsistent, posing challenges for remote patient monitoring.
- Recognizing critical respiratory events like agonal breathing requires reliable data transmission.
Purpose of the Study:
- To determine optimal network settings for identifying agonal respiration in ambulances.
- To evaluate the impact of video resolution and frame rate on telemedicine accuracy for respiratory pattern recognition.
Main Methods:
- Emergency medical technicians viewed videos under various network conditions, assessing respiratory patterns.
- Agonal respiration identification accuracy and time delays were recorded and compared to expert physician assessments.
- The study analyzed the influence of different video resolutions (e.g., 15-fps vs. 30-fps) and network scenarios.
Main Results:
- Overall accuracy for respiratory pattern recognition was 80.7%.
- Accuracy for normal and absent breathing was high (93.3% and 96%, respectively), but lower for agonal breathing (64.3%).
- A higher frame rate (30-fps) significantly reduced time delays in recognizing agonal respiration compared to 15-fps (52% vs. 21%).
Conclusions:
- Frame rate is a critical factor for accurate agonal respiration recognition via telemedicine, more so than video resolution.
- Optimizing frame rate is essential for improving emergency medical response through telemedicine under limited network conditions.

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

The neural regulation of respiration is a meticulously coordinated process primarily controlled by the respiratory centers located within the brainstem. These centers, composed of specialized neurons, transmit nerve impulses that control the contraction and relaxation of our respiratory muscles.
Respiratory Centers in the Brainstem
Two primary areas comprise the respiratory center: the medullary respiratory center in the medulla oblongata and the pontine respiratory group in the pons. The...

Introduction
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...

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...
