Paramedic Recert EMS Care | 23-MCIT-F3-4102 | Capnography

 

Paramedic Recert EMS Care | 23-MCIT-F3-4102 | Capnography starts with the introduction to the topic. It outlines the coverage and objectives. The course delves into the different aspects of carbon di-oxide and its context in capnography, including difference between oximetry and capnometry. Further lessons discuss the types of monitors like colorimetric, digital, and digital waveform followed by the types of capnography. Applications , analysis and inferences from the capnographic data are discussed. Capnography usage in intubated patients and on-intubated patients plus analysis of abnormal waveforms are covered in detail.

The lessons covered are :

  • Lesson 1:  End-Tidal CO2 Assessment.
  • Lesson 2:  Types of Et CO2 Monitors.
  • Lesson 3:  Capnography.
  • Lesson 4:  Capnography: Applications And Indications.
  • Lesson 5:  Capnography In Intubated Patients.
  • Lesson 6:  Capnography in Non-Intubated Patients. And,
  • Lesson 7:  Abnormal Capnographic Waveforms.

Core Concepts & Takeaways

The course Objectives are

  • Interpret blood oxygenation levels using pulse oximetry and capnography.
  • Discuss how EtCO₂ measures ventilation and perfusion.
  • Confirm the phases of the EtCO₂ waveform of a capnography.
  • Analyze an EtCO₂ reading to:
    • Assess and monitor proper endotracheal tube placement.
    • Determine and monitor effective ventilation, and,
    • Determine and monitor effective perfusion.

An expert from the chapter Paramedic Recert EMS Care | 23-MCIT-F3-4102 | Capnography

It is essential to understand the features of the normal capnographic waveform, including contour, baseline level, and rate and rise of the carbon dioxide level.

A typical waveform has four distinct phases:

Phase I:  Called the respiratory baseline (A-B), it is the initial stage of exhalation; the gas sample is dead space gas, free of CO2.

Phase II: Indicated by B-C, this is called the expiratory upslope. At point B, alveolar gas mixes with dead space gas, causing an abrupt rise in CO2 levels.

Phase III represents the expiratory or alveolar plateau and is shown as C-D.  The gas sampled is essentially alveolar.  Point D reflects the maximal Et CO2 level or the alveolar CO2 level. The height of the waveform at point D correlates with the numeric value of exhaled CO2 displayed on the cardiac monitor or defibrillator.

In Phase IV, or inspiratory downstroke (D-E), fresh gas is introduced. This displaces CO2, causing the waveform to return to the baseline CO2 level, approximately 0 mm Hg.

The duration (width) of each waveform corresponds to the duration of ventilation, and the space between waveforms corresponds with the patient’s respiratory rate.
