BONUS: A pаtient with а histоry оf end-stаge emphysema presents tо the ED with the following symptoms: HR 145, RR 32 bpm, B/P 172/99, mild intercostal retractions, SpO2 85 on 2 L/NC and expiratory wheezes bilaterally with fine crackles bibasilar. ABGs on 2 L/NC are as follows: 7.48, 51 mmHg, 48 mmHg, 41 mEq/L. The patient is stabilized and admitted for further observation and evaluation in the AM by his PCP. During routine nightly VS check the patient exhibits the following: HR 122, RR 28 bpm, B/P 168/90, SpO2 87% on 2 L/NC while sleeping. The sats are reported to the nurse and the liter flow to the nasal cannula is increased to 5L/min which brings the patient’s SpO2 to 98% while sleeping. In the morning you enter the patient’s room to administer a nebulizer treatment with albuterol and you note the patient is not easily rousable. You draw ABGs and they are as follows: 7.32, 72 mmHg, 76 mmHg, 40 mEq/L. What would you account to the patient’s ABG changes and what would you recommend to correct the condition?
