MSA is an acronym for “medical apparatus that allows a patient to breathe.”
It’s a breathing device designed to allow a patient with asthma to breathe in the same way as a regular lung.
It works by sucking air into the lungs through a special valve that opens when the patient’s heart rate reaches 120 beats per minute.
MSAs are currently used for patients with chronic obstructive pulmonary disease, COPD, or asthma, but it’s been popularized in the past few years as a way to make breathing easier for people with chronic lung disease.
In the U.S., MSAs can cost thousands of dollars, and the device manufacturer has been accused of misleading the public.
But the company is selling its products through its website.
You can order one through Amazon for $1,700.
Amazon offers several MSA products, including the MSA C2.
A similar breathing device, the MCA1, is also available through Amazon.
The MSA A2, which costs $1.7, is a different device.
It uses a sensor inside the device to detect when the wearer is breathing and adjust the air flow accordingly.
Unlike the Msa A2 which uses a device that can detect when a user is breathing, the A2 uses an electronic sensor inside a special vacuum tube that allows the user to breathe at a rate of 30 breaths per minute while maintaining a controlled amount of air.
These devices have been popular among people with COPD and people who use them for a variety of reasons, such as for sleep, exercise, and general relaxation.
And there are MSA-compatible inhalers, as well.
Air-inhaler manufacturers include Anheuser-Busch InBev, Breathe, Breathesmart, Cargill, and CVS.
