Abstract:
We report the case of a 68 years old patient with platypnea orthodeoxia syndrome who has been clinically suspected on cutaneous saturation position's variation. It has been confirmed by transthoracic and transesophageal echocardiography (TEE). TEE showed the size of patent foramen ovale (PFO), visualised the right to left shunt. A right heart angiography confirmed echocardiographic data and allowed successful closure by a Cardioseal percutaneous transcatheter button device implantation. Symptom's disappearance and a TEE control after 2 months confirmed the success of the procedure.

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Hyperpnea and Hyperventilation
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Alterations in Respiration II
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...
