Maintaining normothermia is a critical component of perioperative care, directly impacting patient outcomes and recovery times. Inadvertent perioperative hypothermia can lead to serious complications, including increased risks of surgical site infections, unfavorable cardiovascular events, and prolonged hospital stays. At SourceMark Medical, we are committed to advancing patient care and understand the need for reliable and effective patient warming solutions.

The Power of a Complete Warming Portfolio

SourceMark Medical is uniquely positioned to support your clinical needs by being the only medical device supplier in the country offering a complete portfolio of patient warming solutions. This allows your facility to standardize patient warming protocols with a single, trusted partner. Why does having access to all three warming technologies from a single supplier matter? It streamlines procurement, simplifies training, and ensures you have the right tool for every clinical scenario.

By partnering with SourceMark, you gain a strategic partner dedicated to providing innovative solutions that fit seamlessly into your existing workflows. This integrated approach empowers your team to deliver consistent, high-quality care. Let’s explore the three primary methods of patient warming—convective, resistive, and conductive—and how each can be utilized to improve patient safety and surgical outcomes.

Convective Warming: The Standard of Care

Convective warming is becoming the new standard for preventing and treating hypothermia in surgical settings. SourceMark’s KoZee patient warming system is the next innovation in advanced convective warming technology. This technology works by circulating temperature-controlled air through a specially designed disposable blanket that covers the patient.

Key Features and Benefits:

Diffused Air Flow System:

• Consistent and uniform temperature distribution
• Less blanket loft
• Three levels of temperature ranges

Advanced Filtration Capabilities:

• Pre-filter layer removes particles and impurities from the air, prolonging the life and effectiveness of the HEPA filter.
• HEPA filter is 99.999% efficient at removing airborne bacteria and virus-carrying particulate.
• Air is filtered again as it diffuses through the microporous material of KoZee air blankets.
• KoZee blankets are 99.4% efficient at filtering aerosolized bacteria and 98.8% efficient at filtering aerosolized viruses.

How It Works:

• Efficient Heat Transfer: The KoZee system gently distributes warm air over the skin’s surface, effectively warming the patient before, during, and after surgery. The continuous flow of air ensures consistent and efficient heat transfer.
• Versatility: SourceMark’s KoZee warming blankets are available in a variety of sizes, making them adaptable to different surgical positions and procedures. Whether it’s an adult or pediatric upper body, lower body, or full-body application, there’s a blanket designed to provide optimal coverage without interfering with the surgical site.
• Clinical Effectiveness: The KoZee blankets are designed of microporous material which enables air to diffuse softly into the microclimate, eliminating blanket lofting and warm air from escaping into the operating room. It also includes a ceramic heating element which creates less secondary heating with less fire risk.

Resistive Warming: Flexible and Targeted Heat

Resistive warming technology offers a different yet highly effective approach to maintaining normothermia. Instead of using air, this method utilizes warming pads containing flexible, carbon-based heating elements. SourceMark’s Astopad® resistive, reusable patient warming system is safe and simple to operate. It helps to prevent and treat hypothermia throughout the perioperative journey for all surgical patients.

Key Features and Benefits:

Efficient, Dual-Channel Patient Warming with Precise Control and Superior Comfort:

• The Astopad® has two independently controlled connections enabling the patient to be warmed simultaneously – these two connections can be run with only one controller.
• Warming blankets can be placed over or underneath the patient. The blankets are soft, flexible, and fully capable of being wrapped around the patient, unlike competing resistive warming devices that are reported to be rigid and stiff.

Flexible, Patient-Friendly Design with Advanced Heating Technology:

• The temperature settings of the controller range from 32°C – 39°C and can be set individually in precise 0.5°C increments.
• All Astopad® blankets are made of proprietary Carbotex® radiolucent heating technology.

Versatile Blanket Sizes with Advanced Safety Sensors and Rechargeable Battery:

• There are five total blanket sizes. Each adult size is designed with 8 sensors enabling enhanced patient safety and precise temperature control, and the pediatric blanket has 6 sensors.
• The Astopad® has a rechargeable battery, which means it can be unplugged and used for patient transport.

How It Works:

• Even Heat Distribution: The resistive elements generate consistent and even warmth across the entire surface of the blanket. This eliminates hot spots and ensures the patient receives gentle, controlled heat. It also can heat multiple body regions separately, offering customizable and efficient coverage.
• Silent and Air-Free Operation: Because it does not rely on forced air, resistive warming is completely silent and does not disrupt the sterile air environment of the operating room. This is particularly beneficial in procedures where maintaining ultraclean air is vital, such as orthopedic and cardiac surgeries.
• Cost-Effectiveness & Sustainability: Unlike forced-air systems that require single-use blankets, resistive systems are reusable—reducing waste and ongoing supply costs. The Astopad® warming blankets are washable, antibacterial surfaces that are easy to disinfect.

Conductive Warming: Advanced Fluid and Patient Warming Solution

Conductive warming is the transfer of heat from a warming device to the patient via direct physical contact. SourceMark’s Norm-O-Temp® is a whole-body system that allows conductive warming therapy to be administered. It can be used in the operating room, pre-op, recovery or emergency department and when paired with Gelli-Roll®, it makes the perfect temperature management device for your OR.

Our underbody warming solution delivers unobstructed patient access, making it ideal for surgical procedures where clinicians need full visibility and positioning flexibility. When paired with the Gelli‑Roll®, it not only enhances cost-efficiency but also simplifies normothermia management by reducing the need for disposable supplies. Available in adult, pediatric, and infant sizes, its setup is easy to place and manage across various clinical settings, offering both practicality and reliable patient warming.

Key Features and Benefits:

Pre-warming Capability:

• The Norm-O-Temp® can be used to prewarm the Gelli-Roll® pad with water at a temperature ranging from 32°C – 42°C prior to start of patient care.
• Ability to pre-condition the water helps save time for the caregiver.
• The Norm-O-Temp® has dual connection sites to accommodate two Gelli-Roll® pads simultaneously which allows for proactive temperature management.

Minimal Airborne Contamination Risks:

• Continuous circulation of temperature-controlled water is pumped through reusable connecting hoses into the Gelli-Roll® pad without disrupting airflow of sterile field. This allows for minimal sound.

How It Works:

• Safely Manage Temperature: The Norm-O-Temp® precisely controls circulating water temperature within 0.6°C of the set point. Once the desired temperature is reached, the heater cycles on and off to maintain it. Each unit has a high-limit safety with a sensor that shuts the unit down, activates an alarm, and displays ERR if the water exceeds the limit.
• Silent and Air-Free Operation: Like resistive warming, conductive warming is completely silent and does not disrupt the sterile air environment of the operating room. This is particularly beneficial in procedures where maintaining ultraclean air is vital, such as orthopedic and cardiac surgeries.
• Cost-Effectiveness & Sustainability: The Norm-O-Temp®, when paired with the Gelli-Roll®, is a great cost savings solution for managing normothermia because of its reusability. This helps to reduce waste and ongoing supply costs. The Gelli-Roll® is easily wiped down with hospital approved disinfectant.
