Purpose:
End-tidal carbon dioxide (ETCO(2)) monitoring has a variety of clinical applications in critically ill pediatric patients. This study was designed to explore the current availability and utilization patterns for continuous ETCO(2) monitoring in pediatric intensive care units.
Methods:
A Web-based survey was distributed to directors of all accredited pediatric critical care fellowship programs in the United States.
Results:
Sixty-six percent of directors completed this survey. One hundred percent of directors had access to ETCO(2) monitoring for intubated patients and 57% for nonintubated patients. Eighty-three percent of respondents used ETCO(2) monitoring "always" or "often" for endotracheal tube confirmation. Fifty percent of respondents used ETCO(2) monitoring "always" or "often" for cardiopulmonary resuscitation, 38% for moderate sedation, and 5% for acid-base disturbances. All respondents who used ETCO(2) monitoring felt that it was easy to use. The most common reason for not using ETCO(2) monitoring was lack of availability (75%).
Conclusions:
End-tidal carbon dioxide monitoring is widely available and used for intubated patients. However, it could be applied more frequently in other clinical situations in pediatric intensive care units.

The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Assessment of Ventilation II: Respiratory Depth and Rhythm
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:
Assessment of Ventilation I: Respiratory Rate
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.
