I thinlung hian engtiang chiahin nge hna a thawh? Cardiac Output chungchang hi han sawi ila!

Vawiin hian kan taksa peng pawimawh tak thinlung chungchang kan sawi dawn a ni. A bik takin, thinlung hian kan taksa pum puiah thisen a pump chhuah dan tur kan sawi dawn a, chu chu cardiac output an ti a ni. Heng thute hi i tan chuan thil thar deuh angin lang mah se, a takah chuan a awlsam khawp mai. Hei hian eng nge a awmzia tak tak i en ang u, kan ti ang em?

Cardiac output chu eng nge ni? A awlsam zawngin...

A awlsam zawngin, cardiac output chu minute khat chhunga i thinlungin i taksa pum puia thisen a pump chhuah zawng zawng a ni. Hei hi litre-a teh a ni tlangpui. Doctor-te chuan hei hi equation awlsam tak hmangin an chhut thin. Thil pahnih a mamawh a ni:

1. Stroke Volume: Hei hi i thinlungin i taksaa thisen a pump chhuah zat a ni a, chu chu a beng apianga, chu chu heartbeat vawi khat chauh a ni. Hetiang zat hi a inang lo thei. Hetiang thisen hi i thinlung hriselna leh chawlh hahdam emaw, thil engemaw i tih emaw a zirin a pung thei a, a tlahniam thei bawk.

2. Heart Rate: Hemi hi i hre tawh ngei ang. Hei hi minute khata i thinlung a nat zat a ni. A tlangpuiin mi hrisel chuan a chawlh laiin minute khatah 60 leh 100 inkar vel a ni tur a ni. Hei hi exercise i tih hian a pung a, i chawlh laiin a tlahniam bawk.

Chuvangin, heng pahnih hi kan hriat chuan, equation Cardiac Output = Stroke Volume x Heart Rate hmangin total value kan hmu thei ang.

Hetiang hian han ngaihtuah teh. Stairs flight khat chu i chho chak zawk a ni. I taksa ruhte hian oxygen an mamawh tam zawk a ni lawm ni? Chuvangin i heart rate a sang a, i thinlung hian a vawi khata thisen a pump zat (stroke volume) tihpun a tum thin. Chutah chuan i cardiac output a pung a, a chhan chu i taksa hian thisen leh oxygen a mamawh tam zawk a ni.

Engtikah nge doctor te hian he cardiac output hi an zawn thin?

Okay, tunah chuan zawhna i nei a, engtik laiin nge doctor te hian he cardiac output hi an zawn thin, a dik em? A chhan hrang hrang a awm thei.

• I tih thin angin exercise lak harsa i tih chuan , emaw, thawhrimna tlemte pawh nise thawk harsa i tih chuan.
• I doctor chuan heart failure ang chi natna i nei nia a rinhlelh chuan , chu chu thinlungin thisen a pump tha thei lo tihna a ni.
• Natna dik taka hriat a ngai a nih chuan.
• Hei hi damdawi, hmanrua, emaw enkawlna i pek tawh zawng zawngte chu a thawk tha em tih hriat chian nan teh a ni bawk .

Cardiac output a tlahniam chuan eng symptom nge a awm theih?

Thinlung in taksaa thisen a pump chhuah zat, a nih loh leh cardiac output a tlahniam chuan kan taksa peng hrang hrangin oxygen leh nutrients an dawng tlem hle. Hei hian symptoms a thlen thei a, chungte chu:

• Exercise hi a har hle mai:Rei vak lo ka kal hnu pawhin ka luak chhuak a, ka chau hle.
• Chau lutuk tih hriat: Ding reng chung pawha chau tih hriat.
• I kut leh keah a hring: Ke, a bik takin ke ruhte chu a hring thei.
• Thâwk a tawi: A châng chuan mut lai pawhin thawk a harsa thei.
• Nausea leh luak chhuak.
• Pum natna.

Heng symptoms te hi i neih hian cardiac output i nei tlem tihna a ni lo. Mahse, heng symptoms te hi a la awm reng a nih chuan doctor thurawn lak a tha ber.

Doctor-te hian engtin nge cardiac output hi an teh? Thiltih dan hrang hrang a awm!

Doctor-te hian cardiac output tehna atan hian hmanraw hrang hrang a awm a. Ṭhenkhat chu a awlsam hle a, ṭhenkhat erawh chuan hmanraw bik an mamawh thung. Eng nge an nih hi han thlir ila:

• Oxygen consumption measurement: Hei hian i taksa chhunga organ emaw tissue emaw pakhatin oxygen a hman zat a teh a ni. I thisen kalna kawnga oxygen awm zat leh i thisen kalna kawnga oxygen awm zat inthlauhna en a, chu chu thisen kal chak dan nena chhut a ni.
• Thisen lum tehkhin dan: Thinlung hmun hrang hrangah, entirnan, vena cava emaw, atrium dinglam emaw-ah catheter bik dah a ni a, chuta thisen lumna chu lung lama thisen phurtu pulmonary arteries-a thisen lum leh lum nen tehkhin a ni. Hei hi thermodilution method an ti bawk .
• Pressure leh resistance tehna: Hei hi i arteries-a pressure average (Mean Arterial Pressure) lak a, thisen kalna kawng kal tlanga thisen kal theihna resistance (Systemic Vascular Resistance) hmanga then atanga hmuh theih a ni.
• Portable devices: Portable devices a awm bawk a, gas chi hrang hrang, i ka atanga i thawk chhuah theih tur a awm bawk.
• Electrode hman dan: Test pakhat a awm a, chutah chuan electrode paruk vel chu rilruah dah a ni. Hei hian heart rate leh stroke volume a teh a, cardiac output a chhut bawk.
• Transthoracic Echocardiography: Hei hi thinlung scan a ni. Stroke volume chungchangah ngaihdan tha tak a pe thei.
• Heart MRI: Hemi chungchang hi thinlung MRI scan atang pawhin hriat theih a ni.
• Dye injection: Hei hi thisen a luh rualin thinlung dinglamah dye bik inject a, thinlung veilam atanga dye chhuak zat tehna hmanga tih a ni.

He test i tih hian eng nge i beisei tur?

Cardiac output dik ber tur chuan i doctor chuan oxygen i thawh zat a teh a ngai ang a, i artery atanga thisen sample lak a ngai ang a, i lung artery-ah catheter bik dah a ngai bawk ang (Catheter in Pulmonary Artery). Hei hi Right Heart Catheterization tih test neih laiin tih thin a ni tlangpui. He test ni hian i cardiac output leh i thinlung chhunga pressure hrang hrangte i hre thei ang.

Eng nge a rah chhuah? Engtin nge min hrilh?

Awle, tunah chuan heng result-te hian eng nge a sawi tih i en ang u.

Mi hrisel tak chawlh laiin cardiac output hi minute khatah litre 5 leh 6 inkar a ni tlangpui .

Mahse, infiammi thiam tak tan chuan he value hi exercise neih laiin minute khatah litre 35 aia tam a ni thei! Chumi awmzia chu an thinlungin a thawk tha hle tihna a ni.

Athlete ni loin exercise a tih hian cardiac output a pung a, mahse athlete angin a pung lo. Tin, naupai lai hian hmeichhiate cardiac output chu a normal level aia sangin a pung a , a chhan chu chutih lai chuan nu taksa leh naute lo thang lian zel hian thisen supply an mamawh vek a ni.

Eng thilin nge kan cardiac output a nghawng?

Kan cardiac output hi a inang vek lo. A nghawngtu thil engemaw zat a awm. A nghawngtu lian ber berte han thlir ila:

• Thisen sang (High Blood Pressure): Thisen sang i neih chuan i thinlung hian i thisen kalna kawng (arteries) kal tlanga thisen a nawr chhuah theih nan nasa zawka hna a thawh a ngai a ni. Thlipui na tak kara kal ang maiin ngaihtuah la, a chhan chu i thisen kalna kawng chhunga pressure a sang zawk a ni. Tin, i thisen sang chu i lungah a sang zawk a nih chuan (i lunga hliam vang emaw, emphysema ang chi natna avang emaw pawh a ni thei), chutah chuan thisen pump turin i thinlung hian nasa zawkin hna a thawk a ngai a ni. Hei hian i cardiac output a ti tlem thei a ni.
• Kum upa lam: Kan upat deuh deuh chuan kan thinlung bangte chu a thim zual a, a nghet zual zel bawk. Thinlung hi thisenin a khat rang lo va, a hma angin a khat lo bawk. Hei hian taksaa thisen a pump chhuah zat a ti tlem thei a ni.
• Lungphun a chhiat tawh a nih chuan: Hetiang thil a lo thlen chuan thinlung hian heart attack hma ang khan thisen a pump tam thei lo mai thei. Tin, heart muscle myocarditis an tih infection chuan heart pumping ability a ti tlem thei bawk.
• Heart rhythm pangngai lo, atrial fibrillation ang chi: Hetiang dinhmunah hian heart chambers chunglam (atria) te hian thisen chu a pump tha thei lo va, lower chambers (mitra) kaltlangin taksaah a thawn lut thei lo. Cardiac output pawh a tlahniam bawk.
• Aortic Stenosis hi aorta panna valve tihtlem a ni a:Aorta hi thisen kalna kawng bulpui ber a ni a, taksaah thisen a phur lut a ni. Chuvangin a panna valve chu a zim a nih chuan taksaah thisen a thawn tling thei lo.
• Constrictive Pericarditis: Thinlung chhehvela venhimna bawm, pericardium , a tight chuan thinlung chu a hahdam tha thei lo va, thisen a khat thei lo va, pump tha thei lo bawk. Hei hian cardiac output a tichhe bawk.

Engtin nge kan cardiac output hi level tha takah kan dah theih ang?

Okay, tunah chuan Cardiac Output a pawimawh chhan leh eng thil nge a nghawng tih kan hre ta. Chuti a nih chuan, level tha takah a awm theih nan eng nge kan tih theih ang? Kan thinlung chakna leh kan thisen kalna kawng hrisel taka vawn reng hi a pawimawh ber a ni. Chutianga ṭanpui thei thil ṭhenkhat chu hetiang hi a ni:

• Exercise neih fo: Ni khatah minute 30 tal kea kal, tlan, cycle khalh ang chi thil ti rawh.
• I cholesterol level control: A bik takin i cholesterol "tha lo" (LDL) chu tihtlem la, i cholesterol "tha" (HDL) level chu hrisel level-ah dah rawh.
• If you have diabetes , i doctor thupek zawm a, nun hrisel tak neih a pawimawh.
• Chaw thau leh fried te hi a theih ang anga tih tlem: Hengte hian thisen kalna kawngah thau a tipung thei a ni.
• Rihna hrisel tak vawn reng: Thau lutuk hian thinlung a tibuaitu a ni.
• Zuk leh hmuam hman loh tur: Meizial zuk hian thinlung leh thisen kalna kawng a tichhe nasa hle.
• A tul chuan doctor-in a tih angin damdawi ei la, i thisen sang control rawh.

A tawp berah chuan thil hriat reng tur (Take-Home Message) .
