Answer 1

Stethoscope- it is a medical device used by doctor nurse or students to listen sounds in the human body especially heart sounds, bowel sounds etcetera.

Esophageal stethoscope- mainly used in surgical settings for anaesthetized patients to check cardiac and respiratory sounds. Some stethoscope has temperature monitoring probe also.

Electrocardiograph - machine used to record the tiny electrical signal produced in heart to pump blood all over the body.

Pulse oximeter- it is a device that monitors saturated oxygen in blood and pulse rate by passing light of two wave length.

Apnea monitor- it is a device used to detect breath cessation of infants or adults who are at risk of respiratory failure monitor heart rate as well. When chest stops moving it will produce sound to become alert.

Doppler ultrasound-

Used to measure the amount of blood flow through arteries and veins of upper and lower extremities by passing high frequency sound waves.

Oscillometric method- it is a noninvasive method to measure blood pressure, measured by sensing the magnitude of oscillation as blood pumps.

Capnometer- used to measure carbondioxide concentration in exhaled air.

Central venous pressure- blood pressure in the venecava near to right atrium. it also measure the venous return and amount of pumping out of oxygenated blood from heart.
