Which signs and symptoms distinguish hypoxemic from hypercapnic respiratory failure? (select all that apply) a. Cyanosis b. Tachypnea c. Morning headache d. Paradoxical breathing e. Use of pursed-lip breathing - ️️a. Cyanosis b. Tachypnea - Clinical manifestations that occur with hypoxemic respiratory failure include cyanosis, tachypnea, and paradoxical chest or abdominal wall movement with the respiratory cycle. Manifestations of hypercapnic respiratory failure include morning headache, pursed-lip breathing, and decreased respiratory rate with shallow breathing. An important consideration in selecting an O2 delivery device for the patient with acute hypoxemic respiratory failure is to a. always start with noninvasive positive pressure ventilation. b. apply a low-flow device, such as a nasal cannula or face mask. c. be able to correct the PaO2 to a normal level as quickly as possible. d. base the selection on the patient's condition and amount of FIO2 needed. - ️️d. base the selection on the patient's condition and amount of FIO2 needed. - The selected O2 delivery system must be able to deliver oxygen in enough concentration to maintain partial pressure of O2 in arterial blood (PaO2) at 55 to 60 mm Hg or higher and arterial O2 saturation (SaO2) at 90% or higher (at the lowest O2 concentration possible). This might range from a simple face mask to intubation and mechanical ventilation. Several methods are available to provide O2 to patients in ARF. The device selected depends upon the patient's overall physiological condition, degree of respiratory failure, ability to maintain a patent airway, the amount of FIO2 that the device can delivered, and most importantly, the patient's ability to sustain spontaneous ventilation.
