Title: What flow pattern is delivered when the air mix control is pushed in and the Bird Mark 7A is ... Post by: lover on Feb 25, 2018 What flow pattern is delivered when the air mix control is pushed in and the Bird Mark 7A is operating on source gas (venturi not being used)?
A) rectangular B) sinusoidal C) oscillating D) ascending ramp Q. 2 A respiratory therapist is examining the sole creases on the feet of a full-term neonate. What characteristic should she find? A) Continuous deep creases that are readily apparent on the entire sole B) Creases that appear as faint red lines C) Creases covering two-thirds of the sole D) Creases covering only the anterior portion of the foot Q. 3 FIO2 delivery increases during inspiration while the Bird Mark 7A is operating using air mix. Which of the following contribute to this fact? I. Increasing pressure in the pressure chamber decreases air entrainment. II. At 12 cmH2O, the venturi gate closes. III. After about 12 cmH2O, gas flow through the circuit is source gas. IV. Excess flow (source gas) is directed through the timing cartridge. A) I B) I and II C) I, II, and III D) I, II, III, and IV Q. 4 The nitrogen washout technique utilizes what percentage of oxygen? A) 100 B) 80 C) 50 D) 10 Q. 5 The apnea (expiratory timing) control should not be used during intermittent positive-pressure breathing (IPPB) therapy, due to: A) asynchrony B) pressure delivery C) high oxygen concentration delivery D) excessive expiratory time Title: What flow pattern is delivered when the air mix control is pushed in and the Bird Mark 7A is ...
