1 I-mmersion sensorâ¢ adjusts internal pressures automatically in response to patient weight, morphology and position maintaining the lowest possible interface pressures.  1 in 4 alternating low pressure cycle supports 75% of patient weight all of the time.
What receptors adapt most slowly? Nociceptors are the receptors that adapt most slowly. Other  receptors include smell, touch, and pressure receptors, which adapt  faster than nociceptors. Making the world better, one answer at a time.
Beta 2 receptors - smooth muscle relaxation - bronchodilator. Alpha 1 receptors - smooth muscle contraction. Alpha 2 receptors - smooth muscle contraction and neurotransmitter inhibition. Here is a link to a good table (I know it's just Wikipedia, but the table is easy to read) http://en.wikipedia.org/wiki/Adrenergic_receptor.
