Memory Game independent and dependent variablesOnline version Game about independent and dependent variables: It consists of describing each programmed and resulting variable, indicating what it is and its normal value. The objective is to find the correct pair between the variables. by Karen Angel Mechanical ventilation Gas exchange at the alveolar level. This allows for the maintenance of adequate PaO2. The entry and exit of an airflow to the lungs, a flow driven by a pressure gradient created by the machine, thus determining lung expansion. oxygenation It allows the ventilator to open its inspiratory valve when demanded by the patient, either by flow or by pressure. It is the amount of air that the ventilator sends to the patient with each breath. It is the number of breaths per minute (rpm) that should be programmed. FiO2 trigger Respiratory Rate This is the time it takes for the gas to enter the lungs through the airways and be distributed within them. It is the percentage of oxygen contained in the air supplied by the ventilator; it can vary from 0.21 to 1. It is the fraction of time spent on inspiration and expiration in each respiratory cycle. Inspiratory flow PEEP Inspiratory Time R I:E Ramp time is the time it takes to reach maximum pressure from the start of inspiration. It is equivalent to flow rate and is programmed in seconds. continuous positive airway pressure that prevents collapse during end-expiration. ramp or inspiratory delay Tidal volume It is the speed at which air enters the airway. It has four types: decelerating, accelerating, constant, and sinusoidal. FiO2 According to age: Neonates 0.25–0.5 Infants 0.5–0.8 Children 0.8–1.5. It is programmed directly or indirectly in volume and pressure modalities. A Vt of 7 to 10 mL/kg weight is programmed, or according to lung protection parameters, 6 to 8 mL/kg weight. Respiratory Rate inspiratory flow Initially, the FiO2 should be set to 1 and then gradually decreased, ensuring adequate oxygenation. Given the toxicity of oxygen, an ideal FiO2 should be below 0.6. Tidal volume Maintaining an inspiration:expiration ratio should generally be 1:2 to 1:3. Ramp slope (s) 0.02-0.4 Inspiratory delay 5-10% It is related to age, and around 25-30 rpm is recommended in infants, 20-25 rpm in children and 12-20 rpm in older children and adolescents. Trigger PEEP Inspiratory Time If there is no lung disease, it is programmed between 3 and 5 cmH₂O, increasing by 2 cmH₂O as needed to maintain adequate oxygenation. It should be adjusted so that the patient can open the valve with the least possible effort. Flow between 1 and 3 L/min and pressure between -1 and -2 cmH2O R I:E ramp or inspiratory delay Inspiratory flow (L/min), according to age Neonates 5–8 Infants 10–12 Toddlers 12–20 Older children 20–40 The main determinants of PMva correspond to (Vc), (PIM), (Ti) and (PEEP). medium pressure It is used to monitor hyperinflation; it consists of suspending the flow at the end of inspiration for more than 3 seconds. Maintain a plateau pressure less than 30 cmH₂O presion inspiratoria maxima Maximum pressure generated during the inspiratory phase of mechanical ventilation that overcomes airway resistance to airflow. MIP between 20 and 25 (never greater than 30) plateau pressure The change in volume relative to the change in airway pressure varies with age and exhibits different behaviors depending on how it manifests. airway resistance force that opposes the entry of flow determined by flow velocity, length and radius of the airway, and the properties of the inhaled gas. static compliance Compliance dynamic compliance It reflects the contribution of airway resistance to airflow. It is calculated by dividing the tidal volume by the difference between the maximum inspiratory pressure (MIP) and PEEP. It provides an estimate of the total compliance of the pulmonary system; it is calculated by dividing the tidal volume by the difference between plateau pressure and PEEP. It is the volume of gas that the ventilator delivers to the patient in each minute of ventilation. It is the product of Vt and RR. minute volume guaranteed volume Pressure-cycled volume mode operates during spontaneous breaths. The ventilator applies variable pressure support with decelerated flow to achieve the programmed tidal volume. Respiratory rate alarm PIM alarm Its objective is to avoid hypo- and hyperventilation, adjusting between 20% and 50% above or below the patient's minute exhaled volume. Vmin expired alarms Its objective is to alert against excessive spontaneous ventilations that may cause hyperventilation or fatigue, by programming a 20% above the normal respiratory rate for the age. In all modalities outside the neonatal period, they should be programmed at 35–40 cmH2O or usually programmed about 10 cmH2O above the value that the patient reaches. apnea alarm It activates when the patient and/or the ventilator do not perform any ventilation for a preset time. Depending on the patient's age, the apnea time is programmed between 10 and 20 seconds. Difference between PIM and PEEP. Increases CO2 sweep (normally 15 to 20). oscillations (HZ) Frequency at which the amplitude oscillates. Per kilogram: 0.2 to 12 kg: 10 Hz 13 to 20 kg: 8 Hz 21 to 30 kg: 6-7 Hz > 30 kg: <5 Hz Amplitude
