1- Introduction
1-1 Device description and intended use
The Respina P1 ventilator system is intended to be used with adult and pediatric patients
weighing more than 5 Kg in the ICU. This system is designed in such a way that can provide
invasive and non-invasive mechanical ventilation for patients. The ventilator is a high risk
medical device (class III according to Health Ministry of Iran and class II b according to
European Union) intended for use by qualified, trained personnel at the discretion of a
physician.
Some features of the Respina P1 ventilator are:
Mandatory and supportive ventilation modes
Volume- controlled, pressure- controlled and volume targeted pressure-controlled
breath types
Detecting respiratory effort of sensitive patient to flow or pressure
Detecting Apnea
Backup ventilation in case of Apnea occurrence (Apnea Backup)
User-selected oxygen concentration
Numeric parameters display
Respiratory curves display
72 hours Trending time
Nebulizer functions
Smart alarm system
Ideal Body Weight (IBW) calculator
1-2 Contraindications
There are no absolute contraindications for ventilator. However, in some specific diseases,
special measures must be taken to prevent possible injury to the patient. Additionally, Non-
invasive ventilation (NIV) should not be used in the following cases:
Inability to trigger breath
Intolerance of interface
Facial or brain injury
Partial or complete airway obstruction
Haemodynamic instability
It is strongly NOT recommended to use the ventilator in the following situations:
Starting and operating the ventilator in the absence of competent medical
professionals supervising the procedure.

10
If there is no alternative ventilation method and equipment that can be used as a
backup.
Connected the device to an inadequate electric mains power (e.g. without earth
connection).
With gas supply which do not meet medical grade specifications.
It is NOT possible to use the ventilator when any of the following events occurs:
Never use it in the presence of flammable anesthetic gases.
Do not use nitric oxide, helium or mixtures containing helium as input gas supply.
The ventilator is located in the vicinity of MRI equipment or significant sources of
electromagnetic radiation.
During the inter hospital transfer of patients (mobilization outside the assigned
institution).
Failure to strictly comply with the instructions for use, user and intended use
environment for this ventilator.
If the ventilator is located in a hyperbaric chamber.
It is the responsibility of the user to select the appropriate ventilation mode for the underlying
disease of the patient. For all ventilator settings, the user needs to consider the respiratory
status and the general state of health of the patient in order to optimally adapt the ventilation
settings to the patient's condition.
1-3 Side effects
The instructions for use do not discuss about risks that are obvious to users, consequences of
obvious improper use of the ventilator and potentially negative effects on patients with one or
more illnesses.
Generally, mechanical ventilation may lead to negative effects, such as barotrauma or strain
on the circulatory system. Proper selection of ventilation mode and suitable adjustment of
setting parameters could decrease potential occurrence of such effects.
Side effects of NIV ventilation includes: ear discomfort, conjunctivitis, skin abrasions due to
mask/patient interface, and gastric distention (aerophagia).
1-4 Warnings and safety information
Warning
Read User manual carefully before operating the ventilator system.
The system function can be affected by using unapproved accessories.
The ventilator should only be operated and maintained by trained personnel. In
addition all patients requiring ventilation must be monitored appropriately by
qualified medical personnel.
The guidelines for the use of approved accessories, checking the device function and
the use of the device in appropriate environmental conditions should be followed by
healthcare center.

11
When the device is turned on, audible and visual alarms will be enabled for a few
seconds to check the alarm system. Do not use the device if integrity of the alarm
system is in doubt and contact the Customer Service department.
Use only sterilized tracheal tube.
Prolonged use of tracheal tube may harm to patient.
Due to leaks around the mask, the patient expiratory volume may be different from
the measured expiratory volume in NIV mode.
Before using the device, prepare necessary equipment to monitor expiratory CO2 in
NIV mode.
There could be hazard of electrical shock by opening the ventilator casing. All
servicing and future upgrading to this equipment must be carried out by personnel
trained and authorized by manufacturer.
Only medically pure oxygen which is oil-free should be used for ventilation. Do not
use anesthetics and explosive gases.
To prevent fire hazard, keep all ignition sources away from the system.
Ensure that an alternate source of ventilation is always available.
In case of uncertainty of device performance, replace the respina ventilator with
another ventilator or ventilation device.
If the ventilator is damaged and ventilation fails, stop using the ventilator because it
may lead to the patient death.
To avoid risk of electric shock, the device must be connected to a mains supply with
proper grounding.
When the ventilator is connected to an external device, the power cable should be
used to ensure proper grounding.
To prevent EMC effect on the ventilator, the device should not be used adjacent to or
in conjunction with other equipment and if adjacent use is necessary, the device
should be observed to verify normal operation in the configuration in which it will be
used.
Do not use cellular phone in the vicinity of this equipment. High level of
electromagnetic radiation emitted from such devices may result in strong interference
with the ventilator performance.
Do not replace any accessories or other parts of the device during the patient
ventilation.
Adding attachments to breathing system may decrease pressure and affect the
ventilator function.
Before using the ventilator ensurethat a battery with minimum charge is installed.
If you’re going to store the device for an extended time, charge the battery and
remove it from the device.
Do not use the device in case of the battery failure.
If the oxygen sensor is faulty or uncalibrated, measurement values will not be
reliable.

12
The maximum time taken to increase the oxygen concentration in the delivered gas to
the patient from 21% to 90% is 12 seconds (in the volumes 30, 150 and 300 ml).
The device maintenance should always be accomplished in conformity with safety
regulations.
The ventilator must be repaired, assembled, and used by trained personnel. The
ventilator must be inspected by trained personnel annually.
To prevent cross contamination, a bacteria filter can be placed between the ventilator
to patient outlet and the patient breathing circuit.
Do not reuse disposable filters and check them regularly for blockages, because
occlusion of these filters can cause high resistance of breathing circuit.
There will be some risks of the environment pollution associated with the disposal of
the device accessories and parts (e.g. battery, defective accessories). The device and
accessories shall be disposed of in compliance with relevant regulations. Contact your
municipality to check where you can safely dispose of old batteries.
Do not sterilize the ventilator.
If the ventilator is damaged, its life-supporting function will no longer be guaranteed.
In this condition do not use the ventilator and use other source of ventilation.
Do not use the ventilator placed next to a curtain, this could block cooling air thereby
causing the equipment to overheat.
To prevent electric shock while servicing the ventilator, ensure that it is disconnected
from all power sources.
Do not use the ventilator in magnetic resonance imaging (MRI) environment.
Do not use the ventilator in high- pressure enclosure.
Do not use the ventilator with nitric oxide.
Do not use the ventilator with helium or gas mixture containing helium.
Maintenance, sterilization and cleaning of the device should be conducted according
to the manufacturer recommendations in the user manual.
Use humidifier or HME to prevent delivery of dry and low temperature air to the
patient. Do not use the HME and the humidifier at the same time, because it increases
resistance of the airway.
Humidifier failure can cause delivery of low moisture and temperature air to the
patient.
Nebulizer or humidifier could increase resistance of breathing circuit filters. User
must check airway filters regularly.
To prevent possible damages, always turn off the humidifier when the ventilator is off
or in standby mode.
Nebulizer can add gas to the breathing circuit and affect the device measurement
accuracy.
In case of unavailability of the oxygen source, Nebulizer will not function.
To ensure that last settings and data are saved, shutdown the device by shutdown key
in standby menu.
Useful life of the device is 10 years.It is recommended to calibrate the device once a
year.

13
Note:
1- The ventilator is equipped with a safety valve that functions mechanically to keep the
pressure below 110 cmH2O.
2- The required time for oxygen concentration to reach from 21 to 90%, in volumes of 30,
150 and 300 ml, in the worst case, is less than 2 minutes.
