Choosing a video laryngoscope ICU teams can rely on is a high-stakes decision. Intubation in intensive care is one of the most dangerous procedures critically ill patients undergo, because they have little reserve and deteriorate fast. This guide reviews what the major trials show, explains which device features matter in critical care, and sets out how to equip every bed space.
Why ICU intubation carries high risk
Intubation in the operating room usually involves a fasted, stable patient. In the ICU, the picture changes.
Critically ill patients often have hypoxemia, low blood pressure, acidosis, or a full stomach. Clinicians call this the physiologically difficult airway. Even when the anatomy looks normal, the patient may desaturate or become unstable within seconds.
The international INTUBE study published in JAMA showed how often this happens. It followed 2,964 patients across 197 sites in 29 countries. Overall, 45.2% had at least one major adverse event during intubation, and cardiovascular instability was the most frequent.
Notably, clinicians in INTUBE used video laryngoscopy in only 17% of cases. Since then, practice has shifted quickly.
What the evidence shows for a video laryngoscope in the ICU
The DEVICE trial is the strongest randomized evidence so far. It enrolled 1,417 critically ill adults in emergency departments and ICUs across the United States.
First attempt success was 85.1% with video laryngoscopy and 70.8% with direct laryngoscopy. However, the rate of severe complications was similar between groups. The trial stopped early because the benefit on first attempt success was clear.
A secondary analysis of INTUBE in the British Journal of Anaesthesia looked specifically at video laryngoscopy. In that observational data, video laryngoscopy was not associated with overall major adverse event risk. Therefore, the honest summary is this: video laryngoscopy improves the chance of success on the first try, while other factors drive complications.
Those other factors matter just as much. For example, the PREOXI trial found that preoxygenation with noninvasive ventilation cut hypoxemia from 18.5% to 9.1% compared with an oxygen mask. Similarly, hemodynamic preparation and an experienced operator both shape outcomes.
Hyperangulated or Macintosh blades in the ICU
Blade choice is still an open question in critical care. Hyperangulated blades give a better view in difficult anatomy, yet tube delivery can be harder. Macintosh-style video blades allow a familiar technique and a direct view if blood or secretions cover the camera.
The INVIBLADE ICU trial is currently comparing hyperangulated and Macintosh video blades in ICU patients. Until results are available, many units stock both.
For a deeper review, see our guide to hyperangulated vs Macintosh blades for difficult airways.
What guidelines say about video laryngoscope ICU use
The Difficult Airway Society 2025 guidelines recommend that video laryngoscopy be available for every tracheal intubation and used as a first line option. Our DAS 2025 summary explains the details.
In the United States, the ASA practice guidelines also support video laryngoscopy as a primary approach in predicted difficult airways. You can read our breakdown of the ASA guidelines for video laryngoscopy.
Taken together, these guidelines make a video laryngoscope ICU standard rather than an optional extra.
Features that matter in a video laryngoscope ICU setting
ICU work places specific demands on equipment. When comparing devices, critical care teams should look at these features.
Speed to readiness. The device should power on and show a clear image within seconds. In a crashing patient, delay costs oxygen.
Portability. A compact monitor moves easily between bed spaces, rooms, and isolation areas. As a result, one device can serve several beds without a bulky cart.
Battery performance. Long battery life and quick charging prevent a flat device at the worst moment.
Screen visibility. A screen the whole team can see helps the assistant pass a bougie or tube at the right time.
Blade range. Adult ICUs need Macintosh 3 and 4 and at least one hyperangulated option. Mixed units may also need pediatric sizes.
Infection control. Single-use blades remove reprocessing steps, which helps during outbreaks of respiratory infection. In contrast, reusable blades need validated cleaning and disinfection. Our guide to video laryngoscope sterilization protocols covers the standards.
Recording. Video capture supports quality review, audit, and teaching, which many ICUs now track.
How to equip every ICU bed space with a video laryngoscope
A video laryngoscope locked in a storeroom helps no one. Instead, units should plan access so that no team waits for equipment.
A practical approach includes:
- placing a video laryngoscope on every airway trolley,
- keeping at least one backup device in the unit,
- standardizing the same platform across ICU, emergency and theatre,
- checking charge and blade stock on every shift,
- storing single-use blades with the device, not in a distant store.
Standardization matters most. If the ICU uses the same monitor as the emergency department and operating room, clinicians do not have to relearn equipment during a crisis. Our article on a universal video laryngoscope monitor platform explains this approach.
An ICU intubation checklist that includes the device
Many ICUs now use a checklist before every intubation. A video laryngoscope ICU checklist usually confirms:
- The team assigns roles, including operator, assistant, and drug giver.
- Preoxygenation is underway, ideally with noninvasive ventilation if suitable.
- Blood pressure support is ready, including fluids and vasopressors.
- The video laryngoscope is on, charged, and showing a clear image.
- A second blade, bougie, and supraglottic airway are on the trolley.
- Waveform capnography is running.
- The team agrees on Plan A, Plan B, and Plan C.
Checklists do not replace skill. Still, they reduce missed steps when the unit is busy.
Training ICU teams on a new device
New equipment brings new risks if teams do not train on it. For that reason, a structured rollout matters as much as the purchase.
A good rollout plan usually includes:
- hands-on sessions with manikins before the first clinical use,
- supervised first cases for clinicians new to hyperangulated blades,
- short refresher drills during regular shifts,
- review of recorded cases to share learning,
- clear cleaning instructions posted near the storage point.
Hyperangulated blades need particular attention. Although the view is often excellent, tube delivery needs a shaped stylet and a different hand position. Consequently, clinicians used to direct laryngoscopy may need several practice sessions.
Respiratory therapists, nurses and junior doctors should also train together. In many ICUs, the assistant matters as much as the operator, because the assistant passes the bougie, watches the monitor, and calls out saturation. Our article on video capture for airway management training shows how recorded views support team learning.
How Astra-vue fits critical care
For a video laryngoscope ICU rollout, Astra-vue offers a compact platform. The Mini Monitor has a 4-inch touchscreen, a 720p HD camera, and about 85 minutes of battery life. It records video and still images to 16GB of storage, and mini HDMI output lets teams show the view on a larger screen for teaching.
Reusable Ultra Blades include Macintosh 1 to 4, Miller sizes, and hyperangulated designs, including a channeled hyperangulated blade. For infection control, the Pro Blade and the anti-fog Lite Blade give single-use options. The system is FDA registered and listed, CE marked under MDR, and built under ISO 13485.

Video laryngoscope ICU FAQs
Does video laryngoscopy improve outcomes in the ICU?
It improves first-attempt success, as DEVICE showed. However, severe complication rates were similar, so preoxygenation and hemodynamic preparation remain essential.
Which video laryngoscope blade is best for ICU intubation?
There is no single answer yet. Many units stock Macintosh and hyperangulated video blades, and the INVIBLADE ICU trial is comparing them directly.
How many video laryngoscopes does an ICU need?
Every airway trolley should have one, with at least one backup in the unit. Larger ICUs often need more to avoid delays.
Are single-use blades better for the ICU?
Single-use blades simplify infection control and remove reprocessing time. However, they add cost per case and waste, so many units mix single-use and reusable blades.
Why is ICU intubation riskier than intubation in theatre?
Critically ill patients often have low oxygen levels, low blood pressure, and little reserve. In INTUBE, 45.2% had at least one major adverse event.
