November 13, 201312 yr We are having discussions about the hemodynamic effects of HFOV. Do you believe there is a threshold where one has to expect cardiovascular compromise if you turn up MAP on HFOV? How best to counter this? Or would you consider this a contraindication for HFOV?
November 13, 201312 yr I have thought that impeded hemodynamics (during HFOV) is related to over-expansion of the lungs, i.e. only at distending pressures exceeding what is needed to get an optimal lung volume. But, I think you're after a threshold for intrathoracal pressure, which can be achieved with high settings, despite yet suboptimal lung volumes ? Look forward to hear from others on this topic!
November 20, 201312 yr more MAP more hypotension so dont forget the role of 9 if the patient is already hypotensive HFOV with high MAP will compromise him more
February 20, 201412 yr comment_7465 I think Dr.Kotb meant by the rule of 9 is not exceed 9 ribs on chest xray as indication of lung volume I gess. Send Sticky Note
