Irregular breathing pattern: thin extremities and enlarged neck muscles, dependent edema secondary to right sided heart failure, clubbing of fingers and toes, pallor and cyanosis of nail beds and mucous membranes, decreased 02 sat, lab tests.

Clients who have chronically increased paco2 levels usually require 1-
