Does non-invasive ventilation worsen or improve patients with concurrent heart failure?

I have heard that non-invasive ventilation can worsen heart failure. However I have also heard it can improve those with heart failure, I think because it redces the preload on the heart by reducing venous return as there is an increased intrathoracic pressure.

Anyone know for certain?

This is from BMJ Best Practice for Acute Exacerbation of Congestive Heart Failure:

Maintenance of oxygen saturation

Oxygen therapy should be given to all patients to maintain oxygen saturation between 95% to 98%, to maximise tissue oxyg

Non-invasive ventilation has been employed in the treatment of heart failure for some time. One reason as you have mentioned correctly is decrease in preload. The other being improved oxygen through recruitment of alveoli by administering positive pres

Hello,
Non-invasive ventilation (NIV) is of use, primarily in patients who are in respiratory failure Type II. NIV definitely improves oxygen saturation levels through several mechanisms, even if the patient also has co-existing left ventricular fa
