What the RT actually does during an intubation
To the family in the hallway, an intubation looks like one person leaning over a stretcher with a blade. To the team in the room, it is a choreographed effort that depends on the respiratory therapist as much as it depends on the person at the head of the bed. Handing over a laryngoscope is the smallest part of the job.
Before anyone reaches for a blade
The RT owns the airway plan from the moment we walk into the room. I check the bag valve mask, confirm a good seal, and pre oxygenate the patient. I set up the suction (Yankauer hooked up, on, and tested), put a working capnograph in line, and lay out the airway equipment in the order it will be used. The endotracheal tube of the size the provider asked for, plus one size smaller as backup. The stylet shaped to the operator's preference. A syringe with 10 mL of air clipped to the pilot balloon. A bougie within reach. A supraglottic device staged for rescue. A second blade ready if the first is the wrong fit.
Then I look at the patient. Are we set up for ramped positioning if the patient is obese? Is the bed at the right height for the operator? Is the head of the bed clear for the provider to step behind it? Is there a second set of hands for cricoid pressure or external laryngeal manipulation if that gets called for?
The work I do before the medications are pushed determines how the next two minutes go.
During the intubation
Once sedation and paralysis are given, the room gets quiet on purpose. I am watching the saturation, the heart rate, the blood pressure, and the patient. I am calling out vitals if anything moves in a meaningful way. If the saturation drifts down, I am ready to mask ventilate between attempts. If the operator asks for a smaller tube, a different blade, a bougie, or cricoid pressure, I have it in hand before the request finishes.
I am also the second pair of eyes on the airway itself. A view that looks great from the operator's side sometimes looks different from beside the bed. If I see the tube going posterior into the esophagus, I say so out loud and we restart. Egos do not protect lungs.
Confirming the tube
Once the tube is in, the work is not done. I confirm placement with continuous waveform capnography (the gold standard), bilateral breath sounds, chest rise, and absence of epigastric sounds. I note the depth at the lip or teeth and document it. I secure the tube and connect the patient to the ventilator with initial settings appropriate for the indication. ARDS patient: lung protective volumes from the first breath. Asthmatic: longer expiratory times and a strategy to avoid breath stacking. Trauma with possible C spine injury: careful neck handling and a plan if positioning has to change.
Then I get the next ABG, look at the chest film for tube position and any new pathology, and adjust.
When it goes sideways
A difficult airway is the moment teamwork either earns its pay or fails. The RT helps the operator stay on a clear algorithm. We bag between attempts. We mask carefully if rescue ventilation is needed. We call for help early. We get the supraglottic device in if intubation fails twice. We anticipate the surgical airway tray if it looks like we are heading there.
Calmness in the room is contagious. So is panic. The RT's voice is one of the loudest in shaping which one wins.
Why this matters
The patient does not know any of this is happening. They will wake up in the ICU with a tube in their throat and a story their family will tell them later. What they will not know is that there was a respiratory therapist three steps ahead of the operator the entire time, making sure the equipment worked, the position was right, the rescue was staged, and the first breath the ventilator gave them was the right one.
Intubation assist is not a passive role. Done well, it is one of the most skilled things we do.
