SOLUTIONS FOR VENTILATORS Sensors and Switches Application Note A ventilator is designed to move a mixture of air and oxygen into and out of a patient’s lungs to either assist in breathing or, in some cases, do the mechanical breathing for a patient who is breathing insufficiently or is physically unable to breathe. BACKGROUND Ventilators are used in hospital intensive care or high dependency units, during patient transport or at homes, to provide assisted breathing or to provide breathing for patients who are no longer able to breathe for themselves. Honeywell sensor and switch solutions are designed to enhance the performance and reliability of ventilators, monitor patient breathing and ensure the safe and efficient operation of the equipment. (See Figure 1). Supporting a vital function, the breathing machines need to be stable, accurate and reliable. The assistance provided by ventilators is personalized for each patient and can be set and adapted at any time to the patient’s specific breathing conditions and needs. SOLUTIONS FOR VENTILATOR APPLICATIONS • Airflow Sensors • Temperature Sensors • Pressure Sensors and Transducers • Humidity/Temperature Sensors • Oxygen Sensors • Magnetic Sensors • Basic and AML Switches • Barcode Scan Engines & Software •

TruStability® HSC Series, SSC Series PRESSURE SENSORS AND TRANSDUCERS Board Mount: TruStability® HSC; Basic ABP & ABP2 Series Heavy Duty: MIP, MLH Series; FP5000 Series Functions/Actions • Monitor a patient’s breathing and detect if breathing deteriorates • Detect when air and oxygen inlet filters are clogged and need to be replaced • Heavy duty pressure sensors monitor and control the flow of air and oxygen delivered to ventilators • Used to test ventilator valves TABLE 3. PRESSURE SENSORS AND TRANSDUCERS FEATURES Honeywell board mount pressure sensors (see Table 3) are extensively used within...

TEMPERATURE SENSORS HUMIDITY/ TEMPERATURE SENSORS OXYGEN SENSORS Honeywell HumidIcon™ Products OOMLF Series • Monitor and control the temperature of the air delivered to the patient, improving patient comfort • Monitor and control the temperature and moisture content of the air delivered to the patient • Measure and control oxygen concentration level of the air mixture delivered to the patient Warm, moist air from ventilators helps to provide the patient with comfortable breathing, reducing sore throats caused by breathing cold, dry air. The 192 Series and 194 Series (see Table 4) are installed...

BASIC AND AML BARCODE SCAN ENGINE PUSHBUTTON SWITCHES & SOFTWARE DM, V15W, ZW Series; ZD Series; AML Series Function/Action • Used as on/off operator controls, as well as detection for covers, panels and doors MICRO SWITCH basic switches can be used as presence/detection for covers, panels and doors acting as a fail-safe to prevent switching the machine when doors/panels are ajar (see Table 7). Several series are sealed to protect against fluids. MICRO SWITCH AML Series are available as pushbuttons, key switches and rockers/paddles (see Table 7). They are often used in medical equipment as off/on...

IMPROPER INSTALLATION • Consult with local safety agencies and their requirements when designing a machine control link, interface and all control elements that affect safety. • Strictly adhere to all installation instructions. Failure to comply with these instructions could result in death or serious injury. FOR MORE INFORMATION Honeywell Sensing and Internet of Things services its customers through a distributors.
