Siemens AG has a bit of hope. It's developed a portable sensor that can detect minute increases of nitric oxide in a patient's breath, particles that serve as a sign of an impending asthma attack. The user can then use that information to ingest the correct amount of anti-inflammatory meds. The device is said to be about the size of a cellphone, though unfortunately Siemens didn't specify a model. Like, are we talking a Veer here or a king-sized Nexus S? Inquiring minds want to know.
