    What to look at before buying respiratory trainers and stethoscopes

    Criteria from someone who uses it with patients, not from someone who only sells it.

    A respiratory muscle trainer is only useful for progression if the load is adjustable in cmH₂O, on a scale the patient can reproduce at home. The "level 1 to 5" kind with no number turns the prescription into a guess, and without a measured load you cannot tell whether the patient improved.

    With a stethoscope, what decides whether you hear fine crackles is the seal — of the bell, the diaphragm and the ear tips — more than the brand. If you auscultate all day, soft ear tips make a difference by the end of the shift.
