Difference between peak airway pressure and plateau pressure?
|
Peak airway pressure is pressure in the central airways while plateau pressure is pressure in the lung periphery and alveoli.
|
|
|
Why it the plateau pressure a good marker of?
|
Plateau pressure can help assess barotrauma and is also useful provides information about the chest wall and diaphragm
|

|
Types of mechanical ventilation through ETT
|
*CMV-controlled mandatory ventilation-unconscious patients
*SIMV (synchronized intermittent mandatory ventilation)-minimum respiratory rate and tidal volume *PCV-set inspiratory pressure and RR *PSV-Pressure support ventilation-set inspiratory pressure and CPAP. Decreases the work of breathing during inspiration. this is needed because if a person breaths spontaneously through an endotracheal tube the diameter narrows and there is an increased work of breathing. |

|
What does NIPPV stand for and give examples?
|
Non-invasive positive pressure ventilation (i.e. CPAP and BiPAP)
|
|
|
what are the principles guiding intervention in cardiogenic shock. (Meaning what are you trying to correct in cardiogenic)
|
Improving Flow
Inotropes - dobutamine, milrinone, low dose DA Afterload reduction Reduce pre-load – nitroglycerin, diuretics Treating Ischemia – if present Delivery Revascularization – PTCA, lytics, CABG Resuscitation - EGDT Correct anemia Prevent further clot – ASA, plavix, heparins, statins, G2III-B inh Oxygenation Consumption Slow HR – beta-blockers Manage SVR / blood pressure – meds (nitroglycerin, nitroprusside, IABP) Reduce non – cardiac activity – mechanical ventilation (as work of breathing can account for up to 50% of total oxygen consumption) Remodelling – may not be acute management ACE inhibitors / ARB Beta-blockers Statins |
