Medical devices allowed in cabin carry-on: CPAP, POC, nebulizers, and legal protections
Complete guide to medical devices in carry-on: CPAP, oxygen concentrators, nebulizers, insulin pumps, 14 CFR 382 rights, and FAA RTCA DO-160 compliance.
Direct Answer: Regulatory Summary
No. The FAA does not issue individual "approval" certificates for medical equipment. Instead, equipment manufacturers self-certify that their device conforms to RTCA/DO-160 radio frequency and electromagnetic compatibility standards, printing a formal compliance statement on the exterior label.

14 CFR Part 382: Federal Protections for Medical Passengers
The US Department of Transportation explicitly protects passengers traveling with medical equipment under Title 14 CFR Part 382 (Nondiscrimination on the Basis of Disability in Air Travel). Under § 382.121, airlines must permit passengers to bring assistive devices into the passenger cabin free of charge, and such devices cannot be counted against personal item or carry-on allowances. Furthermore, airlines must provide priority cabin stowage for mobility aids and medical equipment over standard passenger luggage.
Understanding FAA Conformance: The RTCA/DO-160 Standard
A widespread misconception is that the FAA maintains a list of "approved" medical brands. In reality, under FAA Advisory Circular AC 120-110 and 14 CFR § 121.574, medical equipment manufacturers must independently test devices against RTCA/DO-160 Section 21 Category M standards. A device is legally cleared for in-flight operation if its manufacturer label explicitly states: "The manufacturer of this POC has determined this device conforms to all applicable FAA acceptance criteria for POC carriage and use on board aircraft."
Comprehensive Ledger of Permitted Cabin Medical Equipment
The following medical devices are cleared for passenger cabin transport across commercial air carriers:
- Respiratory Devices: CPAP (Continuous Positive Airway Pressure), BiPAP, portable oxygen concentrators (POCs), and battery-operated ultrasonic nebulizers.
- Diabetes Supplies: Continuous glucose monitors (CGMs), automated insulin delivery pumps, glucagon kits, spare insulin vials, and rapid-acting pens.
- Cardiovascular Hardware: External portable automated external defibrillators (AEDs), mechanical heart valve monitors, and portable ECG monitors.
- Infusion & Nutrition: Enteral feeding pumps, IV gravity bags, sterile saline flushes, and peritoneal dialysis fluid boxes.
Airport Security Screening Protocols for Medical Equipment
Screening medical equipment through TSA and CATSA checkpoints follows a structured protocol: 1) Declare your medical device to the screening officer before placing items on the belt; 2) Remove the base unit from its carrying case and place it in a dedicated bin (you may request a clean plastic bag to protect the machine from bin contact); 3) Tubing, nasal pillows, and masks remain inside the case; and 4) Officers may swab the device exterior for explosive trace detection (ETD) residue.
Medical Battery Transport & In-Flight Power Provisions
Lithium-ion batteries powering medical equipment must remain in cabin baggage. Under FAA 49 CFR § 175.10(a)(18), medical batteries rated up to 160 Wh are permitted in reasonable quantities for the traveler’s medical necessity with airline operator approval. Always verify battery charge levels before departure, insulate bare terminals, and carry sufficient battery packs to cover 150% of scheduled flight transit time.
Frequently Asked Questions
Does the FAA formally approve individual medical devices for flight?
No. The FAA does not issue individual "approval" certificates for medical equipment. Instead, equipment manufacturers self-certify that their device conforms to RTCA/DO-160 radio frequency and electromagnetic compatibility standards, printing a formal compliance statement on the exterior label.
Can an airline charge me a baggage fee for my CPAP machine?
No. Under federal civil rights law (14 CFR § 382.121), airlines operating flights to, from, or within the United States cannot charge any baggage fees for assistive devices, nor can they count a medical device bag against your standard carry-on baggage allowance.
Do CPAP machines have to go through the airport X-ray machine?
Yes. TSA officers require CPAP, BiPAP, and nebulizer units to undergo X-ray inspection. The medical machine must be removed from its carrying case and placed in a bin; face masks, hoses, and power cords may remain inside the bag.
Can I bring liquid medication exceeding 3.4 oz on a plane?
Yes. Medically necessary liquids, gels, and aerosols (including prescription cough syrup, sterile saline, liquid nutrition, and injectables) are legally exempt from 3-1-1 volume limits. You must verbally declare them to screening officers prior to X-ray entry.
