While looking at the screen of a BiPAP Vision noninvasive ventilator, you notice the IPAP is set at 15 cmH20 and the EPAP is set at 5 cmH20.  What is the total pressure?

Which of the following indicate normal oxygenation?      I.        A-a oxygen gradient of 100 mmHg      II.       p/f ratio of

Describe in detail the CPAP /Pressure Support Mode

Patients who have unilateral consolidation or atelectasis may benefit from positioning with the affected lung or segments in the nondependent (upright) position to promote better ventilation/perfusion relations.

A patient is on 02 –  30% ventimask.   Abg’s are: pH 7.34, paC02 65 torr pa02 55 torr, HC03 35meq/L.  What type of respiratory failure does this qualify as?

A patient receiving mechanical ventilation has a high minute ventilation (13.0 L/min).  Upon drawing an ABG and analyzing the results you notice the paC02 is 40 mmHg and the pH is normal.  What can you conclude?

Which of the following indicate an increased work of breathing? Active exhalation Paradoxical chest movement Accessory muscle use Spontaneous tidal volume of 6 ml/kg

Calculate the pa02/fi02 ratio if the pa02 from an arterial blood gas is 80 torr, the delivered fi02 is 45% and the PEEP is 5 cmH20.

Which of the following parameters do not increase mean airway pressure?
