Study Details

Brief summary:

This study will compare the sensitivity and specificity of waveform capnography versus colorimetric carbon dioxide detection to identify tracheal placement of the endotracheal tube during intubation of critically ill adults.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

1. Patient is located in a participating unit (ED or ICU)
2. Patient is undergoing tracheal intubation.
3. The clinician intends to use an exhaled CO2 detection device to confirm tracheal placement of the tube.

Exclusion Criteria:

1. Patient is known to be a prisoner
2. Patient is known to be < 18 years old
3. A responsible clinician has determined that sole use of either waveform capnography or colorimetric testing is required for optimal care of the patient.

Interventions and Outcome Measures

Arms

Critically ill adults undergoing emergency tracheal intubation

Adult patients who are undergoing emergency intubation in the ED and ICU

Interventions

Colorimetric carbon dioxide (CO2) detection

All patients will undergo colorimetric carbon dioxide (CO2) detection. The reading will be assessed by a clinician at the bedside who will answer yes or no to the following question, asked after 7 breaths have been delivered following intubation: "Is the color change consistent with a tube located in the trachea?"

Waveform capnography

All patients will undergo waveform capnography. The reading will be assessed by a clinician at the bedside who will answer yes or no to the following question, asked after 7 breaths have been delivered following intubation: " Is the waveform consistent with a tube located in the trachea?"

Primary outcome measure

  • Sensitivity of the test of exhaled carbon dioxide to detect a endotracheal tube positioned in the trachea. [ Time Frame: From intubation until 7 breaths from the ventilator are delivered, approximately 1 minute ]
