Pressure Controlled Ventilation - (PCV) A method of ventilation that is time cycled, pressure limited, pressure controlled and patient, (AC-PCV), or machine, (TC-PCV), triggered. Volume to the lung will be variable and related to pulmonary compliance, time constant, inspiratory time, pressure gradient and flow rate.
Full Answer
The client must always be assessed before attention is turned to equipment. The client with respiratory failure has been intubated and placed on a ventilator and is requiring 100% oxygen delivery to maintain adequate oxygenation.
A) Assure the patient that everything will be all right and that remaining calm is the best strategy. B) Ask a family member to interpret what the patient is trying to communicate. C) Ask the physician to wean the patient off the mechanical ventilator to allow the patient to speak freely.
b. d. To deliberately hyperventilate a patient, each breath needs to be a machine breath (either volume or pressure). The only mode from the choices given that does that is the pressure-controlled continuous mandatory ventilation (PC-CMV) mode.
Pressure support ventilation (PSV) and pressure- controlled continuous mandatory ventilation (PC-CMV) would require the patient to be intubated. Nice work! You just studied 130 terms! Now up your study game with Learn mode.

bradypnea (brad′-ip-ne- ah) Bradypnea is slow breathing. brady- is a prefix meaning slow. -pnea is a suffix meaning breathing.
What is the meaning of the combining form phak/o? lens of the eye.
Which of the following represents the correct division of the medical term subgastric into its component parts? The component parts of the term subgastric are the prefix sub- (below); the combining form gastr/o (stomach); and the suffix —ic (pertaining to).
, myring- [L. myringa, mininga, meninga, membrane fr. Gr. mening-, membrane] Prefixes meaning tympanic membrane or eardrum.

The meaning of palpebr/o is: Eyelid.
Kyph/o. The combining form that means Hump.
Subgastric. Definition. Pertaining to under the stomach. Term.
Ex: subgastric – gastr is the root meaning stomach.
Basic Term Structure Nearly all medical terms contain at least one root. When a prefix is absent, the term begins with a root. Suffix: The suffix appears at the end of a term and may indicate a specialty, test, procedure, function, disorder, or status.
Prefix: tachy- (rapid) Suffix: -pnea (breathing) Medical word : tachypnea. definition: rapid breathing.
Bradypnea is a respiratory rate that is lower than normal for age. Tachypnea is a respiratory rate that is greater than the normal for age. Hyperpnea in increased volume with or without an increased rate of breathing.
For example, the prefix dys (difficult) can be combined with the root pnea (breathing). This forms the term “dyspnea,” meaning difficulty in breathing.
Bradypnea (Greek from bradys, slow + pnoia, breath), British English spelling bradypnoea refers to an abnormally slow breathing rate. The rate at which bradypnea is diagnosed depends upon the age of the patient.
As a trained medical professional, you may be called on to help with CPR, which stands for: manual (by hand) compressions of the chest to restore heartbeat and breathing.

Cardiac catheterization. Cardiac catheterization is a diagnostic procedure in which a catheter is introduced through an incision into a large vein, usually of an arm or a leg, and threaded through the circulatory system to the heart.
Hypertension. The medical term for high (hyper-) blood pressure is hypertension. Hypertension is a risk factor for cardiovascular disease. Consistent readings over the normal values of 120/80mm Hg in adults are considered hypertensive.
Thrombolytic therapy involves the use of intravenous drugs to dissolve thrombi before they can cause a heart attack. Thromb/o means thrombus (clot); -lysis means dissolution, breakdown.
ERCP stands for endoscopic retrograde cholangiopancreatography, in which a contrast medium is injected via a catheter tube through the mouth, esophagus, stomach, duodenum, and then into the bile ducts.
An imaging procedure in which contrast medium is injected via a catheter tube through the mouth, esophagus, stomach, duodenum, and then into the bile ducts. ERCP stands for endoscopic retrograde cholangiopancreatography, in which a contrast medium is injected via a catheter tube through the mouth, esophagus, stomach, duodenum, ...
The suffix -ectomy means surgical removal, so that eliminates two wrong answer choices. My/o means muscle, but myom/o means muscle tumor. Fibroids are myomas.
Breaths that are triggered by the mechanical ventilator are considered mandatory breaths because the ventilator is controlling the timing of the breath and delivering either a set volume or set pressure.
High or low flow rate settings can cause the patient to be out of synchrony with the ventilator. The higher the flow rate the shorter the inspiratory time. Incorrect sensitivity settings can lead to auto-triggering or "locking out" the patient.
This patient has ventilator-induced hyperventilation as evidenced by the partial pressure of carbon dioxide (PaCO2) of 30 mm Hg with a trigger rate of 25 breaths/min. Switching to the volume-controlled intermittent mandatory ventilation (VC-IMV) mode will decrease the number of ventilator breaths the patient triggers by allowing the patient to breathe spontaneously between the mandatory ventilator breaths. This will reduce the patient's minute ventilation and normalize the PaCO2 and pH. Another potential advantage is to put less of a strain on an already hemodynamically unstable patient. There is nothing in this patient's scenario that suggests extubation and use of noninvasive positive pressure ventilation (NIV). Switching to the pressure-controlled continuous mandatory ventilation (PC-CMV) mode will most likely not correct the patient's problem because the patient will still be able to trigger ventilator set breaths and could continue to hyperventilate. Although sedating and medically paralyzing the patient could normalize the patient's acid-base balance, it is not the treatment of choice because of the hemodynamic instability of the patient.
To deliberately hyperventilate a patient, each breath needs to be a machine breath (either volume or pressure). The only mode from the choices given that does that is the pressure-controlled continuous mandatory ventilation (PC-CMV) mode. Volume support ventilation (VSV) is a patient triggered, volume targeted, flow cycled mode of ventilation that has no backup rate and therefore is a purely spontaneous mode. Airway pressure release ventilation (APRV) is designed to provide two levels of continuous positive airway pressure (CPAP) and to allow spontaneous breathing at both levels when spontaneous effort is present. If the patient is not breathing spontaneously, APRV resembles pressure-controlled inverse ratio ventilation (PCIRV) and could potentially elevate the patient's already elevated intracranial pressure (ICP). Volume-controlled intermittent mandatory ventilation (VC-IMV) actually could be made to hyperventilate the patient if the rate is set high enough. The IMV mode is actually used to reduce the effect of patient hyperventilation on acid-base balance. This happens because only the set rate is a ventilator breath; the rest are patient triggered with the patient's own tidal volume.
Full ventilatory support is provided when the ventilator-initiated rates are set at 8 breaths/min or more in the continuous mandatory ventilation (CMV) or intermittent mandatory ventilation (IMV) modes with either pressure control or volume control.
Continuous positive airway pressure (CPAP) is an accepted method used to treat obstructive sleep apnea. Noninvasive positive pressure ventilation (NIV) would be appropriate if the patient had central sleep apnea, since there would be no respiratory efforts during the apnea periods. Pressure support ventilation (PSV) and pressure- controlled continuous mandatory ventilation (PC-CMV) would require the patient to be intubated.
A 68-year-old female admitted for congestive heart failure is in respiratory distress and is being seen by the hospital's medical emergency team in her regular room. The patient is in obvious respiratory distress and is immediately placed on a nonrebreather mask. Physical assessment reveals: pulse 138 and thready; respiratory rate 30, shallow and labored; temperature 37° C; blood pressure 110/68. Breath sounds are bilaterally decreased with coarse crackles on inspiration. EKG shows normal sinus rhythm with widened cardiac output (QT) interval and an occasional irregular beat. No coughing is noted. The arterial blood gas on the nonrebreather mask is: pH 7.34; PCO2 46 mm Hg; partial pressure of oxygen in the arteries (PaO2) is 52 mm Hg; oxygen saturation is 86%; bicarbonate (HCO3−) is 24 mEq/L. The patient is diaphoretic. The most appropriate ventilator mode to manage this patient initially is which of the following?
In preparing to assist in the collaborative process of weaning the patient from a ventilator, the nurse is aware that the weaning of the patient will progress in what order? A) Removal from the ventilator, tube, and then oxygen.
If satisfactory oxygen levels still cannot be maintained, then a neuromuscular blocking agent (WITH PAIN MEDICATION AND SEDATION!) can be used. The nurse and the UAP are helping to take care of the patient who is on a mechanical ventilator.
D) CPAP allows for the elimination of bacterial growth in oxygen delivery systems.
5.)The student nurse uses a no. 12 French catheter.
1345. The standard size catheter for an adult is a no. 12 or 14 French. Infection is possible because each catheter pass can introduce bacteria into the trachea. In the hospital, use sterile technique for suctioning and for all suctioning equipment (e.g., suction catheters, gloves, saline or water).
