Would it make sense to carry a pulse oximeter to test you oxygen saturation when having trouble breathing? I have same type symptoms as everyone else except for once I have managed to calm myself down/rest until the symptoms were less/under control. If oxygen saturation was high or even not declining over repeated tests would it be accurate to say ok not in crisis? Conversely if real crisis that wasnt going to be brought under control by own actions then wouldnt oxygen saturation be low/going down ?

For me the uncertainty of not knowing is this a crisis or is this something I can control makes it worse.
