Crash cart specifications: closure, seal, quick access

In 2019, Anesthesiology published an analysis of 57,312 witnessed in-hospital cardiac arrests across 538 hospitals: when defibrillation or the first medication is delivered within 2 minutes of the start of resuscitation, survival to discharge is 18%; between 3 and 5 minutes it drops to 15%; between 6 and 8 minutes, to 12.8%. In cardiac arrest, the decisive variable is time, and part of that time is spent physically at the crash cart: finding it, opening it, getting the right item in hand.

A second figure completes the picture. In 2022, an observational study published in the Journal of Emergency Nursing assessed the readiness of resuscitation carts: empty oxygen cylinders in 32% of cases, dead batteries or faulty devices in 16%, wrong-size supplies in 16%, missing, expired or unavailable material in 15%. The most uncomfortable detail is that some of these problems turned up on carts that had reportedly been checked multiple times, by different staff.

Read together, these two figures define the nature of the purchase: a crash cart is not furniture.
It is a device whose design, from the closure to the seal to the layout of the compartments, affects minutes that the clinical literature links to survival.

A closure system serves three functions, and they should be assessed separately

There’s a simplification about crash cart closures that we need to remove right away: “it just has to close.”
In reality, the closure serves three distinct functions, which are often confused:

1. Physical security: preventing unauthorized access to emergency medication and costly supplies.
2. Access traceability: knowing that the cart was opened, when, and under what circumstances; this is the data needed for an internal audit after an event.
3. Content integrity verification: certainty that, since the last access, the cart has been restocked to standard.

The approaches available on the market cover these three functions in very different ways.

• A single-use seal on a centralized closure: a single closure point locks all the drawers and is secured with a numbered plastic seal that breaks by hand when needed. No key, no code: opening takes only the time of one motion, and an intact seal certifies that the contents match the last recorded check. In the Francehopital context, this is the approach used on the Persolife line: centralized closure with a numbered, single-use seal in red plastic.
• Mechanical key closure: protects the contents well, but introduces a dependency on a physical object in an emergency situation. The operational question is simple: where is the key at 3 a.m., and how long does it take to find it?

The point is not that one approach is superior in absolute terms; it is that the priority function of a crash cart is immediate opening, and the other two functions must be fulfilled without compromising it.
The specification to consider in the assessment: the system must allow all compartments to be opened in a single motion, with no key, code or electrical power required, while providing visual, recordable evidence of every opening.

Seal traceability: knowing the cart is ready without having to open it

The numbered seal is the simplest answer to a documented problem: periodic content checks are a long, repetitive task, and the literature shows that diligence alone is not enough.
The Journal of Emergency Nursing study cited above also measured nurses’ situational awareness immediately after checking a cart, and found it insufficient, on average, given the criticality of the task: checks do get done, but attention drops with routine.

Quick access is measured in a trial, not read off a datasheet

A crash cart works at the worst possible moment: staff around the patient, little space, maximum time pressure. Accessibility under these conditions is measured with practical trials, with the cart physically present. The trials that experience has taught us to recommend:

• the time for breaking the seal, timed by an operator unfamiliar with the cart
• simultaneous use by multiple operators: during a resuscitation, several people access the cart at once, for medication, for the airway, for the defibrillator; the design must allow this without staff getting in each other’s way (as a concrete benchmark, the Persolife line is designed for simultaneous use by at least three operators)
• access from all four sides: a defibrillator support adjustable with one hand, the back fitted with an oxygen-cylinder holder and catheter holder, side compartments usable without turning the cart, and drawers with a handle running the full width
• the CPR board: removable in a single motion by one operator, without moving the cart; the mounting position (front, side or under the work surface) should be chosen based on the ward’s layout
• handling at full load: a single operator must be able to push, brake and turn the cart along the real route – corridors, doors, elevator – all the way to the point of use

The consequence is organizational: assessing a crash cart should always include a documented practical trial, with measurement criteria defined before the trial.

Standard contents and compartment modularity

The 2021 ERC guidelines recommend standardizing resuscitation equipment across the facility: same cart, same layout, same contents in every ward, so that a staff member responding outside their own ward finds every item where they expect it. Defining the contents is up to the facility, based on the in-hospital resuscitation guidelines it has adopted; it is up to the cart to make that standard workable and maintainable.

Frequently asked questions

What is a crash cart?
It is a cart that brings together, in a single mobile unit, the medication, supplies and devices for managing cardiac arrest and in-hospital emergencies: a defibrillator, airway equipment, emergency medication, a CPR board. It is also referred to as an emergency trolley. It stays closed and sealed until needed.

What is the numbered seal on a crash cart for?
Two things at once: it certifies that the contents match the last recorded check, and it allows the cart to be verified at a glance. An intact seal with a number matching the log means the cart is ready; a broken or missing seal calls for a full check and a new seal before the cart returns to service.

How often should a crash cart be checked?
The 2021 ERC guidelines call for regular checks, with a frequency set by the facility. Under the seal-based approach, checking works on two levels: a daily visual check of the seal and external items, and a full content check at scheduled intervals or after every opening.

What should a crash cart contain?
The facility defines the contents based on the resuscitation guidelines it has adopted; the ERC recommendation is that they be standardized across all wards. It is up to the cart to make that standard maintainable: configurable compartments, a modular vial-holder system, a layout that follows the operational sequence.

What is a difficult airway cart?
It is a cart dedicated to managing difficult airways: it brings together, in order of use, the supplies called for by difficult-intubation algorithms. The specification logic is the same as for the crash cart – immediate opening and standardized contents – with a dedicated compartment layout.
