A solar battery manufacturer wants to predict the arrival time of the batteries to residential homes. To fit a quadratic regression predicting arrival time from distance to the local warehouse, which R code is appropriate? The data set is Delivery.  Distance = the distance from the residential home to the nearest warehouse ArrivalTime = the time that it takes for the product to arrive

Initial FIO2 on CMV that should be set for carbon monoxide poisoning patients is:

A sedated 6 feet patient is on ventilatory support. The patient’s vent settings and arterial blood gas results are below: Mode = AC/VC Rate = 15 breaths/min Tidal volume = 450 ml Oxygen = 40% pH = 7.28 PaCO2 = 60 torr PaO2 = 70 torr  HCO3 = 29 mEq/L Based on this information, what would you recommend?

A  5 feet 6 inch patient needs ventilatory support after intubation? What set tidal volume should  be initiated on AC volume control ventilation at 8 ml/Kg?

Restrictive diseases such as Pneumonia, ALI and ARDS causes:

A patient is currently on CMV with the following ventilator settings   Mode – AC/VC Total rate – 20 breaths/min Set Rate – 12 breaths/min VE – 7 lpm Set VT – 400 ml PIP – 25 cm H2O PEEP – +5 cm H2O FIO2 – 45%   What kind of breaths are observed here?

A patient with ARDS is on the current ventilatory support. Current ventilator settings and ABG are provided.   Mode – AC/PCV PIP – 40 cm H2O Rate – 12 breaths/min Total rate – 12 breaths/min Pressure – 30 cm H2O VE – 6 L/min PEEP – 10 cm H2O FIO2 – 1.0   pH – 7.32 PaCO2 – 50 torr PaO2 – 45 torr HCO3 – 26 mEq/L   What should the therapist due at this time?

A patient was placed on ventilatory support secondary to pneumonia. Which manifestations support this diagnosis?   I. Positive Sputum C&S II. Temp 39c III. WBC 8,000 IV. Diaphoresis

Prior to suctioning the patient endotracheally, What must be done?
