Midmark Patient Monitor CO2 Sensor Bracket (Capnography / LoFlo Sidestream)
ETCO2 capnography sensor mount for Midmark multiparameter veterinary patient monitors (8019 series). Bolts to existing screw points on the monitor housing. Secures Philips Respironics LoFlo sidestream modules and compatible sensors. Keeps the module cradled and the cable routed during anesthesia.
Specifications
Compatibility
- Midmark 8019 Series Multiparameter Monitors (8" and 12")
- Philips Respironics LoFlo Sidestream CO2 Sensor
- Respironics CAPNOSTAT 5 Mainstream CO2 Sensor
- Most sidestream CO2 modules with standard LoFlo-compatible form factor
The Problem
Capnography, the continuous monitoring of end-tidal CO2 during anesthesia, is a standard monitor in veterinary surgery, and the 2020 AAHA Anesthesia and Monitoring Guidelines recommend continuous ventilation monitoring for anesthetized patients. The clinical background is covered in our capnography guide. This page is about the hardware.
The Philips Respironics LoFlo sidestream CO2 sensor is the standard capnography module used with Midmark multiparameter monitors. But the LoFlo was designed as a generic OEM component. It ships with no monitor-specific mounting hardware. The module simply hangs from its cable, sits loose on a shelf, or gets taped to the monitor housing.
This creates real problems. Philips and Health Canada issued a safety alert documenting that LoFlo sensor cables subjected to repeated twisting, coiling, or bending can lose functionality. An unsecured module swinging from its cable strains the 8-pin Lemo connector, tugs on the sampling line connection, and is vulnerable to drops that can damage the internal infrared optics.
Your anesthesia team shouldn’t be improvising with tape and zip ties to secure a monitor that’s watching your patient breathe.
The Solution
The CO2 Sensor Mount bolts directly to four existing screw points on the rear panel of your Midmark multiparameter monitor, the same mounting points designed to bear the load of Midmark’s own mounting accessories. No drilling, no adhesive, no modifications.
The mount provides a secure cradle that holds your LoFlo sidestream sensor in place with clean cable routing that takes the load off the connector. The sensor stays accessible for sampling line changes but protected from bumps, swings, and drops.
Designed for the Philips Respironics LoFlo sidestream CO2 sensor, the standard capnography module used across Midmark, Bionet, Edan, Infinium, and other veterinary monitoring platforms. The LoFlo and CAPNOSTAT share the same 8-pin connector and are interchangeable on the same host monitor.

Frequently Asked Questions
Which monitors does the CO2 sensor mount fit?
It bolts to four existing screw points on the rear panel of Midmark 8019 series multiparameter monitors, in both the 8-inch and 12-inch versions. No drilling, adhesive, or modifications are needed.
Which CO2 sensors does it hold?
It is built for the Philips Respironics LoFlo sidestream CO2 sensor, the standard capnography module on these monitors. It also cradles the Respironics CAPNOSTAT 5 mainstream sensor and most sidestream modules with the standard LoFlo-compatible form factor, since the LoFlo and CAPNOSTAT share the same 8-pin connector.
Why secure the CO2 sensor module instead of letting it hang?
The LoFlo ships with no monitor-specific mounting hardware, so the module's weight ends up hanging from its cable and connector. The mount holds the sensor in a fixed cradle with clean cable routing, which keeps the connector and sampling line stable during anesthesia.
What is included, and how do I clean it?
Each mount ships with four screws matched to the Midmark rear panel screw points. Wipe it with isopropyl alcohol. The PETG resists most clinical cleaning solutions, but it is not autoclave safe.
