A patient was is endotracheally suctioned while on mechanical ventilation. The patient’s blood pressure dramatically dropped to 90/60 mmHg from 120/80. What had occurred?

Which of the following clinical observations is most commonly associated with Cor pulmonale?

A Pulmonary function test was established on Mr. Gonzalez. The following results are as follows.                                                   PREDICTED         ACTUAL          PERCENTAGE %FEV1                                  3.8 ml                    2.5 ml                     67FEF  25-75              4.8 L/sec               3.1 L/sec                 64FEF 200-1200         8.3 L/sec              5.8 L/sec                 70TLC                           6.5 L                      4.8L                        75RV                             1.8 L                      1.3                          73What can you conclude from the following results?

A patient just recently inubated and placed on the ventilatory support has the following ventilator settings, patient parameters and arterial blood gas results.Mode = AC                   pH = 7.36 f = 14                            PaCO2 = 50 mmHg      VT = 600 ml                 PaO2 = 48 mmHg FIO2 = 0.70                   HCO3 = 30PEEP = 0 cm H2OPETCO2 = 30 mmHgWhat is the deadspace to tidal volume ratio?

After successful CPR the patient still has a low blood pressure 87/59 mmHg. What medication can be given to increase the BP?

A patient is recieving mechanical ventilation with increased mechanical deadspace. The minute ventilation has not changed. Which of the following will increase?

A patient in the emergency department  is tachypneic and has a pulse rate of 125 bpm. The pulse-ox reading is 86% and the patient is starting to use his accessory muscles. He is currently on oxygen via nasal cannula running at 3 lpm. What should you do at this time?
