Postural nausea due to platypnea orthodeoxia

Area of Science:

• Cardiology
• Pulmonology
• Palliative Care

Background:

• Platypnea orthodeoxia is an uncommon cardiorespiratory condition characterized by worsening dyspnea and hypoxemia in the upright position.
• It is often associated with severe lung disease and advanced age, making it relevant to the palliative care setting.
• Classical presentation involves symptoms that change with posture, prompting consideration in breathless or desaturating patients.

Observation:

• This report details a rare case of platypnea orthodeoxia syndrome presenting primarily with nausea, deviating from the typical dyspnea.
• The patient's symptoms were directly linked to postural changes, a hallmark of the syndrome.
• This unusual manifestation underscores the diverse subjective experiences of physiological events.

Findings:

• Echocardiography is a minimally invasive diagnostic tool for identifying the underlying cardiac defects.
• The condition is potentially treatable with procedures that resolve the anatomical defect, thereby alleviating symptoms.
• This case represents the first reported instance of platypnea orthodeoxia syndrome manifesting with nausea.

Implications:

• Clinicians, particularly in palliative care, should consider platypnea orthodeoxia in patients with unexplained breathlessness, desaturation, or even nausea, especially with positional changes.
• Thorough patient history and physical examination are crucial for diagnosing this condition.
• Recognition and diagnosis can lead to effective procedural interventions and symptom relief.
