Pressure Problems Do Not Wait for Your Next Check

Room pressure does not fail on a schedule. It drifts when doors are opened, when airflow changes, or when power goes doewn. Spot checks only confirm conditions at a single moment in time and leave long gaps with no visibility. When surveyors or infection control ask what happened overnight or over the weekend, manual logs cannot answer that question.

Hidden Infection Control Exposure

Negative and positive pressure rooms exist to contain risk. When pressure falls out of range, exposure can begin immediately. Without continuous monitoring, facilities teams may not know a the environment was compromised until after staff or patients have already entered the space.

Regulatory Gaps That Are Hard to Defend

ASHRAE compliance needs environmental control. If pressure or humidity moves out of range, facilities must show when it happened, how long it lasted, who was notified, and what corrective action was taken. Manual readings and paper logs leave too much unanswered during surveys.

No Context When Something Goes Wrong

When pressure alarms or logs raise concerns, the next question is always why. Was it a mechanical issue, a door left open, or normal room use. Manual checks provide no timeline and no insight, forcing teams to investigate after the fact without reliable data.

Solution

Continuous Visibility Without Manual Checks

Hexmodal Pressure Monitor (HEX-P) provides continuous monitoring of room pressure, temperature, and humidity so facilities teams are not relying on manual logs or local sensors. Conditions are tracked 24/7 and automatically documented, creating a complete record of what happened, when it happened, and how it was resolved. This removes guesswork, closes documentation gaps, and gives teams confidence during surveys and audits.

Know the Moment a Room Goes Out of Range
HEX-P monitors pressure continuously and alerts the right people the moment a room drifts out of range. Issues are identified as they happen, not hours later during a walkthrough, allowing teams to respond before exposure or compounding risk escalates.
CMS-Ready Documentation
Every reading, excursion, and corrective action is automatically logged and stored online. Pass surveys with reports that show exactly when the issue started, how long it lasted, and what was done to correct it.
Context That Explains Why
HEX-P includes a door position sensor and time-stamped data that show whether pressure loss was caused by HVAC airflow issues, door activity, or equipment behavior. This context eliminates speculation and supports clear root cause explanations during reviews and audits.
How it Works

Set It Up Once. Monitor Every Room.

Step 1

Install Sensors in Minutes

Mount HEX P in the room and HEX D on the door. No wiring or IT involvement required.

Step 2

Activate the Gateway

Devices connect automatically through the Hexmodal gateway, which covers up to 250,000 square feet and supports more than 1,000 devices.

Step 3

Monitor status and get reports online

The system tracks pressure differential, temperature, humidity, and door position around the clock. Alerts, trends, and excursion events are logged automatically with survey ready documentation in the dashboard.

    FAQs

    Questions, answered with clarity.

    Does HEX-P meet Joint Commission, DNV, and NFPA 99 expectations?

    Yes. HEX P supports continuous monitoring of pressure relationships, temperature, and humidity, which aligns with Joint Commission EC.02.05.01, DNV NIAHO requirements, and NFPA 99 and ASHRAE 170 environmental criteria. The system provides the documented evidence surveyors want to see when validating air pressure relationships in critical spaces.

    Does HEX-P require WiFi or any connection to the hospital network?

    No. HEX-P uses Hexmodal’s independent low frequency radio and cellular gateway. There is no WiFi, Ethernet, or IT integration, which eliminates IT approvals and avoids cybersecurity barriers.

    What does HEX-P measure?

    HEX P monitors room pressure differential, temperature, humidity, and door position. These data points help facilities teams detect pressure loss, HVAC issues, propped doors, and environmental excursions before they become survey findings or infection control risks.

    How often does the system check room pressure?

    Monitoring is real-time - readings can be set up from 1-minute to daily. HEX P records real time pressure data and logs excursions automatically, rather than relying on once a day manual checks or shift based tissue tests.

    Can HEX-P alert my team when a room goes out of range?

    Yes. Alerts are sent by text, email, or phone call to the right staff member. You can set custom thresholds for each space, including ORs, isolation rooms, sterile storage, and clean utility rooms.

    Do we need to run wiring or add power?

    No. HEX P is battery powered with a typical lifespan of three or more years. Hexmodal provides replacement batteries at no cost and reminds your team before replacements are due.

    Does it include door monitoring?

    Yes. A HEX D door sensor is included to identify when doors are open or propped, which is a common cause of pressure loss and a frequent survey finding.

    How does reporting work?

    The Hexmodal dashboard generates trend graphs, excursion reports, and time stamped logs automatically. Records are stored online and can be exported for surveys, root cause reviews, or infection prevention documentation.

    Can we monitor multiple buildings or offsite locations?

    Yes. One gateway covers up to 250,000 square feet and supports more than 1,000 devices. Large health systems use the same platform to monitor acute care campuses, ASCs, MOBs, and remote outpatient facilities.

    Is support included?

    Yes. 24/7 compliance support, spare parts, batteries, and recalibration are included in the subscription.
