Ms. B is a 47-year-old morbidly obese female who was admitted to the hospital via the ED on 6/22/19 with a chief complaint of shortness of breath (SOB) and congestive heart failure (CHF).
Diagnosis: Chronic diastolic heart failure and chronic respiratory failure
History of Present Illness:
Ms. B has had repeated admission for heart failure. She is now presenting with decompensated diastolic heart failure and acute hypoxic respiratory failure requiring BIPAP when her pulse ox desaturates to the 60-70s. Ms. B has had SOB for 2 weeks which has gotten worse over the last two days associated with dyspnea, paroxysmal nocturnal dyspnea, and BLE swelling. In the ED, she was found to be hypoxic and required 6L of O2 by NC and an ICU consult was obtained. They recommended no need to admit to ICU at that time. She’s currently on a 2g NA diet and was placed on a 1,000 mL fluid restriction.

- Chronic coronary artery disease
- Upper respiratory tract infection
- Acute kidney injury (AKI)
- Chronic kidney disease stage III

Ms. B reports she has never smoked previously or used chewing tobacco, she also reports no alcohol or drug use.
Ms. B has a family history of diabetes, heart disease, heart attack, and hypertension from her mother’s side. Her father is deceased. She used to work as a pharmacy tech and lives with her mother and sister. She is not married and has one son. She identifies herself as a Christian and her hobbies include drawing and listening to music.
Diastolic heart failure occurs when the left ventricle is not properly filled with blood during the filling phase. Consequently, the heart has less blood to pump out to the body. This is caused by thickening of the ventricular walls, which leads to slower relaxation of the ventricle. The heart then increases pressure inside the ventricle to make up for the thickened walls. This manifests as fatigue and exertional dyspnea. Increased pressure inside the ventricle can lead to buildup of blood in the atrium and even into the lungs which can lead to fluid congestion and shortness of breath, edema, fatigue, weakness, and rapid irregular heart beats. The ejection fraction represents the amount of blood that is ejected from the heart after each contraction. A normal ejection fraction is more than 50%. Diastolic heart failure is defined as having symptoms of clinical heart failure with a normal left ventricular ejection fraction. Ms. B’s ejection fraction was recorded as 60-65%.
Side note: Systolic heart failure is when the heart doesn’t contract properly (indicating a pumping problem). While diastolic heart failure is when the heart fails to relax or fill fully how it should (indicating a filling problem).
The function of the respiratory system is to facilitate the exchange of oxygen and carbon dioxide between the blood and the atmosphere. Gas exchange takes place in the alveoli of the lungs. Oxygen molecules in the alveoli cross the alveolar membrane and enter the bloodstream while carbon dioxide from the blood travels out into the alveoli. Respiratory failure occurs when there is no longer that exchange in the body between blood and air. This can be due to fluid filling the alveolar spaces, alveolar space collapse, pulmonary embolism, emphysema, and thickening of the alveolar membranes. Chronic respiratory failure can be divided into two types: hypercapnic respiratory failure and hypoxemic respiratory failure. Hypercapnic respiratory failure occurs when carbon dioxide is not exchanged out and accumulates in the blood (increased carbon dioxide in the blood). Hypoxemic respiratory failure occurs when there are low oxygen levels in the arterial blood.
