Pulmonary Capillary Pressure
Also written as CHF.
Paroxysmal nocturnal dyspnoea (PND) — sudden breathlessness during sleep, waking the patient gasping; caused by frank pulmonary oedema; relieved by standing (gravitational pooling lowers left atrial/pulmonary capillary pressure); patient often seeks air at an open window
What our notes say
- Paroxysmal nocturnal dyspnoea (PND) — sudden breathlessness during sleep, waking the patient gasping; caused by frank pulmonary oedema; relieved by standing (gravitational pooling lowers left atrial/pulmonary capillary pressure); patient often seeks air at an open window (CVS History & Physical Exam: Symptoms, Chest Pain & Syncope — Notes)
- Pulmonary lymphatics & alveolar capillaries – Starling forces, interstitial fluid clearance: When LV pressure exceeds pulmonary capillary pressure, fluid transudates → crackles, Kerley B lines; the examiner may ask what radiographic sign reflects this. (Heart failure: which tests and why)
- Orthopnoea suggests redistribution of fluid from legs/abdomen to lungs in recumbency, increasing preload and pulmonary capillary pressure. (Pulmonary oedema and ARDS)
- \n\nraises pulmonary capillary pressure, causing pulmonary oedema. (Davidson's Essentials of Medicine - 2nd)
- sions may contribute to dyspnea, both by increasing the pulmonary capillary pressures. (Harrisons Pulmonary and Critical Care Medicine)
