thus she is at increased risk for hypercapnic respiratory failure and she does not know it. Hypercapnic respiratory failure in a person who cannot adjust their breathing pattern normally will cause the stereotypic mood, motor activity and behavior seen in manic depressive illness.
Only counting baseline respiratory rate [and depth, if possible] at rest will suggest this diagnosis, making arterial blood gas tests necessary to know PCO2, pH and PO2 in the blood.
If the diagnosis is correct then the treatments will be clear because the deficit is clear. The ventilatory system has been damaged at some point and respiratory support is needed.
