-Severe case lead to (distressed appearance, confusion, blurred vision, loss of
coordination, slow reaction time, somnolence, coma)

\-Tachycardia
-Tachypnea
-Confusion
Patient need of 02 via Non-rebreather based on SPECIAL CONSIDERATIONS. -
\-Pneumothorax

When do you need to increase the flow? -
\When the applied L/min is not causing the Sp02 to return to normal.
Sp02 for normal patient= 95% and above
COPD patient= low 90%s
