Capnography application in acute and critical care

Area of Science:

• Anesthesiology and Critical Care Medicine
• Respiratory Physiology
• Emergency Medicine

Background:

• Capnography (end-tidal carbon dioxide monitoring) has seen expanded use in diverse acute care environments.
• Understanding capnography is crucial for clinicians managing critically ill patients.

Observation:

• This article details the principles and applications of capnography.
• Normal and abnormal capnograms (waveforms) are described to aid in recognizing clinical scenarios.
• Key clinical indications include detecting pulmonary embolism and verifying endotracheal, gastric, or small bowel tube placement.

Findings:

• Capnography provides insights into expiratory breathing patterns.
• It assists in assessing patient perfusion, particularly during cardiopulmonary resuscitation.
• Case studies illustrate the practical application of capnography in acute care settings.

Implications:

• Capnography enhances diagnostic accuracy and patient safety in critical care.
• Its utility extends from airway management to circulatory assessment.
• This monitoring technique is valuable for a wide range of acute medical and surgical emergencies.
