Acute hypercapnic RF in COPD
Cardiogenic Pulmonary Edema
Indications for NIPPV
Immunosuppressed patients with pulmonary
infiltrates, fever and ARespFX
Ventilator management of Manipulation of FiO2 or PEEP
O2
Manipulation of tidal volume and rate
Ventilator Management of
CO2 To retain Co2--> Lower rate/less Vt
To blow off CO2--.> increase rate/Vt
Push: blood in lung space displaces lung to the other
side. Tracheal deviation. Hemothorax
PUSH/PULL SIGN
Pull sign: Air vacuum pulls to affected side.
Pneumothorax
Types of Acute Resp Hypoxemia vs Hypercabia
Failure
Most common cause
PNA, PE, ARDS, Alveolar Collapse, Pulm AV
communication
Increased A-a gradient
Hypoxemic RF V/Q
Mismatch pulmonary vasoconstriction (reduce perfusion) to the
area of the lung with reduced ventilation
hypoxic pulmonary vasoconstriction- unique to pulm
vasculature
responsive to O2 therapy
