LFT, Resp failure, Pul HTN Flashcards
Eosinophilic Pneumonia
Diffuse pulmonary infiltrates on chest x-ray Bronchoalveolar lavage eosinophilia >25% Absence of parasitic, fungal, or other infection Absence of drugs known to cause pulmonary eosinophilia Quick clinical response to corticosteroids Failure to relapse after discontinuation of corticosteroids
Variable Intrathoracic
Causes - tumour, bronchial stenosis
DLCO very low, normal/slightly decreased TLC
Indications for ECMO
Scoring
Resp - ARDS, Aspirtion, Pneumonia, Asthma, Post lung tx, Lung contusion
Cardia - Post AMI, Drug OD, PE, cardiogenic shock
RESP Score - prediction of survival on ECHMO. Factors - Age, Duration of lung injury
Mx of ARDS
NIV indications
Pul edema
COPD
Hypoxic resp failure
Resp Failures - Type 1–>4
Type 1 - hypoxia
Type 2 - hypoxia + hypercapnia
Type 3 - Perioperative Atelectasis
Type 4 - Shock
Elevated PAP - definition, factors
Pulmonary artery pressure >25 or >30 with exercise (but this is being debated to reduce it to 20)
Factors affecting - pulmonary artery pressure, pulmonary vascular resistance, left atrial pressure, cardiac output
Pul Htn Types 1–> 5
