Why choose the Sonosite SII?

Purchasing ultrasound equipment is no small matter, particularly for departments like Anesthesia and Trauma, where both time and space seem to be working against you. So what makes the Sonosite SII a high-performance machine in these settings?

Several key features set the SII apart from other ultrasound solutions.

Fast machine boot-up time

You need an ultrasound machine that is ready to scan, stat. The SII goes from cold start to scanning in under 25 seconds. 

Clarity of ultrasound image

When your trauma bay is packed with medical personnel, it can be difficult to monitor everything. When space is at a premium, the Sonosite SII offers a stunningly clear picture. With its high visibility, non-reflective screen, and wide viewing angle, the Sll displays patient scans clearly from across the room.  

New patented transducer technology

DirectClear Technology, available on the rP19x and rC60xi transducers, is a novel, patent-pending process that elevates transducer performance with improved penetration and contrast resolution. A unique combination of matching and de-matching layers surrounding the transducer’s crystal send more of the ultrasound signal into the body, producing an image that is clear and distinct. 

Armored transducer cables

How often do transducer cables get rolled over, stepped on, or twisted? The rC60xi, rP19x, L38xi, and L52x (vet) transducer cables are surrounded by an embedded metal jacket, protecting your cables from damage. By safeguarding electrical connections inside, armored cables help maintain image quality over the life of your transducer.

Simplified ultrasound controls, interface, and presets

When it’s your job to administer a nerve block, assess internal bleeding, or perform a thoracentesis, you need technology that works right along with you. That’s why the SII has an intuitive user interface, familiar tactile controls, and dual transducer connectors. When time is of the essence, the SII is ready to perform the right exam at the right time with minimal set-up.

Portable ultrasound machine with a small footprint

When space is at a premium, you don’t want an ultrasound machine that takes up one quarter of the room. The Sonosite SII is designed to take up as little space as possible, while still providing crystal-clear imaging. The SII has a zero footprint when mounted on a wall, connected to an articulating arm, or used with a small-footprint optional stand, so you can bring the image closer to you. 

Optional cord management solutions make transporting the machine between rooms easier than ever. The SII’s award-winning design was created using clinician input, as well as thousands of hours of real-time observation of ultrasound machines in use in clinical settings.

Versatile, flexible, and efficient ultrasound exams

With the SII, you can easily switch between transducers and exam types. Two transducers can be connected simultaneously; change from one transducer to the other with two taps of the screen. Two screen taps will also easily switch between exam types on the same transducer. So if you’re performing an abdominal ultrasound exam and need to switch to a vascular exam, you can do it in just seconds.

Award-winning design

The SII was designed after thousands of hours of real-time usage observation, clinician testing, and practitioner interviews. The SII reintroduces features (like physical knobs to adjust gain and depth) that our customers told us improved the ultrasound experience. The Industrial Designers Society of America (IDSA) recognized the Sonosite SII ultrasound in the 36th Annual International Design Excellence Awards (IDEA).

Clinical applications of the SII

The Sonosite SII ultrasound machine is designed for use in multiple clinical areas, but is especially well suited to Anesthesiology, Vascular Access, and Trauma uses. 

SII ultrasound for anesthesia

Regional Anesthesiologists have enthusiastically embraced the Sonosite SII for help visualizing nerves and vascular anatomy while placing regional nerve blocks.

Enhanced image quality and touchscreen controls, combined with nerve exam presets for rapid scanning, make the SII an excellent choice for anesthesiologists who wish to provide the best perioperative pain management. 

The SII is also easy to clean, making it the perfect choice for operating rooms in which infection control is an absolute must. The durable glass screen covers the full face of the SII, and can be disinfected. Touchscreen controls can be simply disabled before cleaning to avoid accidental activation of the machine while disinfecting.

Ultrasound-guided interscalene (brachial plexus nerve) block

For post-operative analgesia, the interscalene block is favored by anesthesia specialists. The SII provides clear visualization of the needle and nerve during block placement, allowing precise placement of local anesthetic with minimal patient discomfort. 

Perioperative ultrasound for volume status management

For anesthesiologists, managing patient volume status is crucial to positive outcomes. The SII’s clear visualization of the IVC, heart and lungs enable anesthesiologists to quickly assess cardiac output, diagnose pulmonary edema and determine a patient’s volume status.

PECs blocks for post-operative analgesia

Thoracic wall blocks such as the Pecs I & II are becoming increasingly popular among anesthesiologists who wish to avoid the risks associated with paravertebral blocks, while striving to provide exceptional post-operative pain management to patients undergoing breast surgery. The SII offers clear visualization of the major and minor pectoral muscles, as well as the pleura and vulnerable vascular structures. The SII’s steep needle profiling helps guide the needle tip for accurate local anesthetic placement. 

SII ultrasound for vascular access 

SII is a preferred machine for ultrasound-guided vascular access. The SII’s clear imaging and simple controls allow clinicians to simply and quickly adjust depth and gain settings to locate accessible locations for guided venipuncture and arterial access. Reduced speckle and enhanced contrast provide strikingly clear images of vascular pathways. 

On patients with challenging vascular conditions, the SII can offer ultrasound guidance for peripheral IV (PIV) placement, often mitigating the need for central venous catheter placement in patients whose venous access is otherwise impeded.  

For critically ill patients (and for those patients for whom a peripheral IV is not possible), the SII is often used for ultrasound-guided CVC placement, drastically reducing the instance of pneumothorax (as opposed to the landmark method). 

Both Color Doppler and Color Power Doppler modes are available on the SII. Visualize the presence and direction of blood flow in a wide range of flow states. 

The SII’s Center Line Guide provides onscreen visual guidelines to help determine the location of vascular pathways during live scans.

SII ultrasound for trauma 

For busy trauma bays, the SII offers an outstanding physical design (zero footprint when mounted on an attenuating arm; very small footprint when used with optional stand). With two built-in transducer connections, trauma specialists can rapidly go from eFAST exam (P19 transducer) to ultrasound-guided central venous catheter placement (with the L25 transducer). The easy-to-clean system also gets approval from infection-control advocates.

SII for cardiac calculations

The SII provides the following calculations for cardiac exams: 

  • Ejection fraction
  • Volume measurements
  • Simpson’s rule
  • IVC Collapse Ratio
  • LA/RA Volume
  • TAPSE 

The SII allows you to view ejection fraction and fractional shortening calculations simultaneously.

“Ultrasound has become an essential component of emergency and critical care veterinary medicine and access to an easily portable, yet durable, ultrasound machine that produces quality images is a must.

At WVRC, we have been thrilled with the Sonosite systems both for the machines as well as for the sales and technical support that comes with them.  

In our ER and ICU, we can be hard on equipment so it was highly important for us to have a durable machine that could stand up to the rigors of near-constant use. The S Vet and the corresponding stand and power pak battery did not disappoint.  In addition, our ER staff needed a machine that was user-friendly and did not require frequent settings adjustments.  With the S Vet, we get a quality image fast and rarely change a setting.  It’s on in seconds and it’s ease of use has helped make ultrasound an easy extension of our initial triage, exam and assessment.  The unit lives in our ICU, a short distance from our triage station, and I don’t know what we would do without it!  

A portable ultrasound was at the top of the equipment request list at our Racine location and it was an easy decision to purchase the S II Vet last year without even considering another brand.  Once again, we have been pleased with the machine set up and design as well as the customer service we have received surrounding the purchase and set up.  The technical support for Sonosite has been equally as impressive. Any issues have been addressed promptly and with great concern.  The company knows how important ultrasound machine availability is to us and when we had a recent probe that required replacement under warranty, they had us back up and running within 48 hours with no hassle at all.  I would not bother looking elsewhere for an ultrasound for the emergency/critical care setting!  Thanks Sonosite for knowing exactly what your customers need!”

Kari Severson, DVM Wisconsin Veterinary Referral Center

Dr. Mandavia, Dr. Mallon, and Dr. Newton discuss portable ultrasound in the emergency department and why it is important to have it at the bedside in that clinical setting. They also discuss the importance of an ultrasound system being easy to use, portable, and reliable.

"I really like that this is designed specifically for anesthesia, because I don’t want anyone else using it.”

David Coventry, Consultant in Anesthesia, Ninewells Hospital, Dundee, Scotland

"The S-Women’s Health ultrasound system is great to have in the exam room because if a patient comes in with a lump, I am able to quickly and easily determine if it is something like fibrocystic thickening, or if it requires additional evaluations. When you consider the quality and affordability of the system and the fact that you can pick it up and take it to the operating room, you just can’t get a better tool for your practice than the S-Women’s Health system."

Deanna J. Attai, MD, FACS, Center for Breast Care, Burbank, California

"I believe that within the next three to five years ultrasound will become a standard for delivering better patient care in the prehospital emergency setting."

David Hildebrandt, NREMT-P, CCEMT-P, Hennepin County Medical Center, Minneapolis, Minnesota

"Sonosite is the only company that has designed a system that can withstand rigorous use in the Intensive Care Unit (ICU). We evaluated a lot of machines and no one else has taken into account what critical care physicians need. Both the S-ICU™ and M-Turbo® have superb image quality and are easy to clean; so essential to infection control. I can foresee the day when there will be an S Series ultrasound tool mounted by every bedside in the ICU.”

John M. Oropello, MD, FCCP, FCCM, Professor of Surgery and Medicine, Program Director, Critical Care Medicine and Co-Director, Neurosurgical-ICU, Mount Sinai School of Medicine, New York

"The use of bedside diagnostic ultrasound has revolutionized the care of critically ill patients and is likely to define the sub-specialty of critical care medicine within the immediate future. In three to five years, critical care physicians will not be able to practice in their field without knowledge of bedside ultrasonography."

Alexander B. Levitov, MD, FCCM, RDCS, Eastern Virginia Medical School, Norfolk, VA

"Very sleek! It reminds me of Bang & Olufsen. The vertical orientation and mounting of the machine is a logistical improvement. Space can be at a premium in an anesthetic room during a hectic day. A vertically mounted machine is both more ergonomic and easier to position optimally in relation to the patient."

Ian Harper, MD, Consultant in Anesthesia, Wansbeck Hospital, Northumberland, England

"The ultrasound-guided technique allows us to use less analgesia, diminishes complications, and helps us avoid stimulating nerves that could cause additional pain or discomfort in the patient."

Paul Bigeleisen, MD, Clinical Associate, Professor of Anesthesiology, University of Rochester Medical Center (URMC), Rochester, New York

"At this point, it would be hard to imagine a case in which I would perform a nerve block or central venous catheter placement without ultrasound. Any time one can see the needle and the target, whether it be nerves or blood vessels, it is going to contribute to greater safety and efficacy."

Gavin Martin, MB, ChB, FRCA, Associate Professor of Anesthesiology, Duke University Medical Center, Durham, North Carolina
