A função primária das células vermelhas do sangue é:

Em um experimento laboratorial, procura-se investigar os sinais eletromiográficos do músculo Bíceps Braquial. Para tal, os eletrodos de superfície do sistema de eletromiografia devem ser posicionados, idealmente, sobre:

Em relação a sarcopenia em decorrência da idade, qual subtipo de fibra muscular parece, proporcionalmente, se atrofiar mais ao longo dos anos?

Para evitar perda de informações de uma medida ao longo do tempo, o teorema de Nyquist requer que:

Um dado sinal discreto no domínio do tempo pode ser decomposto em seus diferentes componentes (i.e., harmônicas) periódicos no domínio da frequência. Uma vez no domínio da frequência, é possível reconstruir o sinal no domínio do tempo apenas com os componentes de interesse (i.e., eliminação de ruído) através da:

Uma das práticas mais comuns para a normalização dos sinais provindos de um sistema de eletromiografia de superfície é:

A função primordial da circulação sanguínea é:

Em referência ao ciclo cardíaco, está correto afirmar que:

Match the meaning of the following words:

1- live part;

2- puncture;

3- overload;

4- insulation;

5- troubleshooting.

( ) a material having a high resistance to the flow of electric current;

( ) the term used when a disruptive discharge occurs through a solid dielectric. A disruptive discharge in a solid dielectric produces a permanent loss of dielectric strength; in a liquid of gaseous dielectric, the loss may be only temporary;

( ) electric conductors, buses, terminals, or components that are uninsulated or exposed and an electric shock hazard exists;

( ) a procedure for the purpose of locating and identifying electrical problems within an electrical system;

( ) operation of equipment in excess of normal, full-load rating, or of a conductor in excess of rated ampacity that, when it persists for a sufficient length of time, would cause damage or dangerous overheating.

Texto para a Questão

The block A consists of circuitry for the audible alarm, the wye hot wire flow sensor, the gas ID, the inspiratory and expiratory pressure transducers, the source gas pressure transducers, the exhaled flow sensor, the FiO2 cell, and communications with the UIM.

A micro-controller is used to generate alarm waveforms for an compliant alarm. A super capacitor is used to provide a minimum of 120 seconds of power without wall AC or a battery.

Analog circuitry is provided to signal condition the wye Hot Wire Flow Sensor signal and a 12 bit ADC is used to digitize the signal. A Flow Sensor Fail signal is provided to allow the Control Processor to determine when the flow sensor wire is broken. The Flow Sensor EEPROM is SPI bus compatible and is read at power up and when a Flow Sensor is connected.

The air inlet fitting contains a resistor for determining which gas source is connected to the Air inlet, Air ( 5K ohm) or Heliox (10K ohm). The type of gas connected is determined with a resistor divider, one half of the divider is contained in a connector and the other half is located on the block A. The resistor contained in the connector is different for each gas source and therefore produces a different voltage output from the divider. The output of the divider is read via an ADC.
