Managing COVID-19 with Airo TruCT

A message from Stryker


People are at the heart of what we do. Now more than ever. That's why we are working around the world to put people first and deliver on our mission to make healthcare better.

Thoracic imaging with computed tomography (CT) is an important tool for pulmonary disease diagnosis and management and has emerged as a useful resource during this pandemic, as demonstrated in the figure below. We are committed to serving healthcare professionals by providing additional information on the appropriate use of the Airo TruCT Mobile CT Imaging System in managing COVID-19.

We appreciate all you are doing for your patients and the communities you serve. Our team around the world is ready to help. Please reach out to or your Stryker representative with any questions.

Unprecedented mobility allows for flexible set-up away from the general patient population

A primary concern related to the use of CT in COVID-19 care is the infection control challenge that COVID-19 patients could present by entering CT scan suites. When CT is needed, the ACR recommends considering the use of portable radiography units in ambulatory care facilities or isolated spaces2.

With its onboard motor and rechargeable batteries, Airo TruCT can travel over one mile and up a 5-degree grade while unplugged, making it possible to be easily wheeled in and out of patient care areas. Airo TruCT's footprint in transport mode ranges from 6 ½ - 7 ½' L x 2' W x 6 ½' H and weighs from 1,800 to 2,150 pounds, based on a configuration with or without an integrated table column. It is designed to fit into a standard hospital transport elevator. Once it reaches its desired location, it is powered by a standard wall outlet.

Airo TruCT's enhanced software and user interface eliminate the need for a control room by providing point-of-care diagnostic imaging.

Thanks to this flexibility, Airo TruCT can be used in several environments such as mobile or fixed Radiology, Intensive Care Unit (ICU), Emergency Department (ED), Surgical/Operating Room (OR), clinic or office.

Utilizing computed tomography (CT) to manage COVID-19

At this time, the ACR, CDC, and other multi-national institutions do not recommend imaging as an initial screening test for COVID-19 in asymptomatic patients, where IVD testing remains the best in this scenario2. However, several studies and statements have been released regarding theappropriate use of imaging in diagnosis and care3 (see additional resources below). A recent multidisciplinary panel, comprised principally of radiologists and pulmonologists from ten countries with experience managing COVID-19 patients across a range of healthcare environments, evaluated the efficacy of imaging within three scenarios representing varying risk factors community conditions, and resource constraints3.

Fourteen key questions, corresponding to eleven decision points within the three scenarios and three additional clinical situations, were rated by the panel. The ratings were based upon the anticipated value that thoracic imaging was expected to provide. The results were aggregated and resulted in five main recommendations and three additional recommendations, which are intended to guide medical practitioners in the use of CXR and CT in COVID-19 management3. A summary has been published in a statement by this panel to aid in COVID-19 care.

Summary of recommendations for imaging3
Main recommendations

Imaging is not routinely indicated as screening test for COVID-19 in asymptomatic individuals
Imaging is not indicated for patients with mild features of COVID-19 unless they are at risk for disease progression (Scenario 1)
Imaging is not indicated for patients with moderate to severe features of COVID-19 regardless of COVID-19 test results (Scenarios 2 and 3)
Imaging is indicated for patients with COVID-19 and evidence of worsening respiratory status (Scenarios 1, 2, and 3)

Additional recommendations

Daily chest radiographs are not indicated in stable intubated patients with COVID-19
CT is indicated in patients with functional impairment and/or hypoxemia after recovery from COVID-19
COVID-19 testing is indicated in patients incidentally found to have findings suggestive of COVID-19 on a CT scan

Managing the patient population

Airo TruCT is designed to use appropriate x-ray techniques across supported age ranges, as defined in the table below and in the Airo TruCT Protocol Guide4. The condition and health of a given patient is left up to the discretion of the physician. For patients immobilized with such devices as stirrups, arm boards, etc. when using CT scanning with Airo TruCT, there are no special conditions of use or dedicated protocols outside of ensuring that table accessories are outside the field of view.
